Homemade bacon is pork belly transformed by salt, nitrite, time, smoke, and later cooking. The technique is approachable, but the cure is not a casual seasoning mix. Precision matters because too little nitrite weakens the protective process and too much is dangerous.

Prague Powder #1 must be measured by weight in grams on a scale that reads to at least 0.1 gram. Never measure it with a teaspoon, never estimate it by eye, and never substitute Himalayan pink salt. Prague Powder #1 contains sodium nitrite and is toxic in excess. Store it labeled, sealed, and completely separate from ordinary salt.

This guide uses the site's conservative cure calculation of 2.5 grams of Prague Powder #1 per kilogram of meat, which produces about 156 parts per million nitrite when the product is the standard 6.25 percent sodium nitrite blend. Enter the trimmed pork-belly weight in the brine & cure calculator rather than doing the decimal math from memory. Check the package composition and follow a tested recipe. Proprietary curing blends are not interchangeable gram for gram.

USDA FSIS explains that nitrite helps inhibit Clostridium botulinum, contributes the cured color and flavor, and slows rancidity. Its bacon safety guidance also makes clear that bacon is still a perishable pork product. Curing is not permission to work warm, skip sanitation, or store a home batch indefinitely.

What you need

The ingredient list is short. The essential equipment is about control, not gadget collecting.

• Fresh, skinless pork belly with an even thickness
• Prague Powder #1 that states 6.25 percent sodium nitrite
• Kosher salt or another plain salt weighed in grams
• Sugar, pepper, and optional spices
• A 0.1-gram digital scale
• A second kitchen scale for the pork belly and bulk ingredients
• A food-safe zipper bag or vacuum sealer
• A rimmed tray to contain leaks
• Refrigerator space that stays at 40°F or below
• A smoker that can run a clean, controlled fire
• A sharp bacon slicing knife or slicer

Use separate scales because a large kitchen scale may not resolve tenths of a gram accurately. Verify the small scale with its calibration weight. If the display jumps by whole grams, it is not suitable for Cure #1.

Choose and trim the pork belly

Buy fresh pork belly, not sliced bacon and not a previously cured slab. Look for a piece with visible lean layers running through the fat. A very thin end cures and smokes faster than a thick center, so an evenly shaped slab is easier to manage.

Skinless belly is simpler for a first batch. Skin slows cure contact on one side and becomes tough during a short hot smoke. If the belly arrives skin-on, ask the butcher to remove it or use a long flexible knife while keeping the blade angled toward the skin. Work slowly. A deep gouge changes thickness and makes slicing less even.

Square ragged edges only enough to make the slab manageable. Save clean trimmings for another cooked dish. Then weigh the finished slab in grams. That post-trim weight is the number used for every percentage and for Prague Powder #1.

Record the weight on the bag before handling cure. A written number prevents a dangerous memory error after the counter is covered with containers and gloves.

Build the cure by weight

An equilibrium-style dry cure scales every ingredient to the meat. The method is more repeatable than rubbing on an unknown amount and discarding whatever does not stick.

For each kilogram of trimmed pork belly, a practical starting formula is:

Ingredient	Weight per kilogram of meat	Purpose
Prague Powder #1	2.5 g	Nitrite cure at about 156 ppm
Plain salt	20 g	Seasoning and preservation support
Sugar	10 g	Balances salt and aids flavor
Black pepper	2 to 4 g	Optional flavor
Garlic or other dry spices	To taste	Optional flavor

The 2 percent plain salt and 1 percent sugar are flavor choices. The Prague Powder #1 amount is a safety measurement. Keep those concepts separate. If you want less salty bacon, reduce the plain salt modestly, not the curing salt. If the Cure #1 package has a different formulation, stop and use instructions written for that exact product.

Run the meat weight through the brine & cure calculator. Write the output beside your recorded belly weight. Weigh Cure #1 into a small cup by itself, verify the display, then combine it thoroughly with the salt, sugar, and spices. Even distribution matters because the total dose is small.

Do not use Prague Powder #2. It includes nitrate for long dry-cured products and is not the cure for bacon that will be cooked. Do not swap in Tender Quick or another proprietary blend. Those products have their own formulas and manufacturer instructions.

Apply the cure and bag the belly

Pat the meat dry. Spread the complete cure mixture over every face and edge, using all of it. Work over a clean rimmed tray so material that falls away can go into the bag. Put the belly and every remaining grain of cure into the bag, press out excess air, and seal.

Label the bag with the meat weight, Cure #1 weight, start date, and planned check date. Place it flat on a tray in the coldest reliable part of the refrigerator, never on the door. The tray protects other food if the seal leaks.

Keep the refrigerator at 40°F or below. That number is cold-storage guidance, not a cure target. Salt and nitrite do not make unsafe refrigerator temperatures acceptable. Keep raw pork below ready-to-eat food and sanitize the scale platform, counter, handles, and tools after bagging.

How long to cure

A typical home slab cures in roughly five to seven days, but thickness matters more than total weight. A wide, thin piece and a compact, thick piece can weigh the same while the cure has a different distance to travel. Follow the timing in a tested recipe for your slab dimensions.

Turn and massage the sealed bag once a day. Liquid will collect as salt draws moisture from the pork. Do not pour it out. In an equilibrium cure, that liquid contains part of the measured cure and remains part of the system.

The belly should become firmer through the week. A soft center at the end of the planned cure can indicate an unusually thick or uneven slab. Do not solve uncertainty by adding more Cure #1. Extra time within the tested method is different from adding an uncalculated dose.

The video below shows the full workflow from a raw belly through curing, drying, smoking, chilling, and slicing. Use it to understand the physical steps, but keep your cure math tied to the exact meat weight and product in front of you.

Rinse, taste-test, and form the pellicle

When curing is complete, remove the belly, discard the bag liquid, and rinse the surface under cold running water. Pat it completely dry. A rinse removes concentrated surface cure and spices; it does not pull the cure out of the center.

Before smoking the whole slab, cut a thin piece from an edge and cook it in a pan. This tests salt level and flavor. The edge is usually more seasoned than the center, so interpret it as a strong sample. If it tastes uncomfortably salty, soak the slab briefly in cold water in the refrigerator, dry it, and test another slice. Do not leave it at room temperature.

For better smoke adhesion, place the rinsed belly uncovered on a rack in the refrigerator overnight. Moving cold air dries the surface until it feels slightly tacky. That layer is the pellicle. Smoke adheres more evenly to it than to a wet slab.

Use a stainless cooling rack over a tray so air reaches the bottom. Keep the refrigerator sanitary and make sure the raw cured belly cannot drip onto other food.

Hot smoke or cold smoke

For a first batch, hot smoking is the more manageable path. The smoker supplies both flavor and controlled heat. Cold smoking keeps the chamber much cooler and is a specialized process with less margin for error. It requires strong temperature control, an appropriate cured product, suitable weather, and a validated method.

This guide does not recommend improvised cold smoking. A cardboard cabinet, smoldering dust, and a warm day can hold meat in unsafe conditions even when the smoke looks convincing. Smoke itself is not a reliable kill step.

Set up the cooker for indirect heat and clean combustion. Mild woods such as apple, cherry, or maple fit bacon well. Hickory produces the familiar assertive profile, but use it sparingly on a thin slab. Avoid resinous softwoods and any lumber that is painted, treated, glued, or of unknown species.

The smoker phase develops flavor and color. It does not turn home-cured bacon into a room-temperature product. Follow the finish and handling steps in your tested recipe, then chill promptly. When you later cook the slices, use clean utensils and prevent raw contact with ready-to-eat food.

Manage the smoke, not just the thermostat

Wait for the initial dirty ignition smoke to clear before loading the belly. Good smoke is light and smells pleasant. Heavy gray or yellow smoke deposits soot and bitter compounds. If the exhaust stings your eyes, improve airflow and combustion before blaming the wood species.

Place the belly where heat is indirect and airflow is even. A thick end should face the warmer zone if your cooker has one. Use a clean rack rather than hanging the slab near a flare-up path. Bacon fat can drip, and grease plus flame is a dangerous combination.

Do not keep adding wood because the surface stopped looking smoky. A cured belly can take on plenty of flavor over a controlled session. Start with a modest fire, taste the finished batch, and adjust the next one. Smoke intensity is much easier to increase later than to remove from bitter bacon.

If cook time is part of your planning, remember the rule: cook to internal temperature, not to the clock. The smoking calculator can organize a general pork cook, but a tested bacon process, slab thickness, cooker behavior, and direct temperature measurement govern this project.

Cooling, slicing, and cooking

Move the smoked belly to a clean rack and chill it promptly according to the tested recipe. Cold bacon firms up and slices far more cleanly than a warm, soft slab. An overnight chill is ideal before slicing.

Slice across the long muscle grain. Thin slices crisp faster and render more completely. Thick slices keep a meaty center and need gentler cooking so the exterior does not burn before the fat renders. A long slicing knife works for occasional batches. A meat slicer improves consistency but adds cleanup and another sharp machine to store.

Home-smoked bacon should be treated as cook-before-eating unless your validated process explicitly establishes otherwise. USDA FSIS lists 145°F with a three-minute rest as the safe minimum for whole-muscle pork on its safe temperature chart, matching MeatLogic's meat temperature chart. Thin bacon is difficult to probe accurately, so cook it thoroughly and evenly rather than relying on color alone.

Storage

USDA FSIS advises keeping raw bacon refrigerated at 40°F or below and using it within seven days or freezing it. Apply that conservative rule to a home batch unless a validated recipe gives stricter guidance. Homemade processing does not create the standardized packaging or shelf-life controls of a commercial plant.

Portion before freezing so you can thaw only what you need. Separate stacks with parchment, vacuum-seal them, label the package with the smoking date, and freeze flat. Thaw in the refrigerator, not on the counter.

Discard bacon that develops a sour odor, sticky slime, unusual gas, or mold. Do not taste questionable cured meat to decide whether it is safe. When a bag has lost its seal or sat above safe refrigeration temperature, uncertainty is enough reason to discard it.

Flavor variations that do not change the cure

Once the safety formula is fixed, the flavor layer can move.

Maple and black pepper: Replace some or all of the sugar with maple sugar and use coarse pepper. Liquid maple syrup changes the wet mass in the bag, so follow a tested formulation rather than pouring freely.

Garlic and bay: Add finely ground dried garlic and crushed bay to the cure. Remove loose leaf pieces before smoking so they do not scorch.

Chile bacon: Add ancho, chipotle, or red-pepper flakes. The smoke can amplify bitterness, so keep very hot or heavily smoked chiles restrained on the first batch.

Pepper-crusted finish: Apply fresh cracked pepper after rinsing and before the pellicle stage. The tacky surface holds it well.

Do not let flavor experiments change the Prague Powder #1 dose. Sugar, syrup, spices, and smoke do not replace nitrite. A recipe that omits curing salt is making a different refrigerated pork product with different handling demands.

Common mistakes

Measuring cure by volume: This is the dangerous one. Crystal size and packing make teaspoons unreliable. Use grams on a 0.1-gram scale.

Confusing pink salts: Prague Powder #1 is not Himalayan salt, and Prague Powder #2 is not the correct substitute. Read the label every time.

Curing warm: The entire cure happens under refrigeration at 40°F or below. Salt is not a replacement for cold control.

Discarding bag liquid mid-cure: That removes part of a measured equilibrium system. Keep it sealed and turn the bag daily.

Smoking a wet surface: Water delays color and makes smoke adhere unevenly. Dry the belly and form a pellicle.

Using dirty smoke: More visible smoke is not automatically more flavor. Maintain clean airflow and a small fire.

Assuming smoked means ready to eat: Treat the finished slab as cook-before-eating unless a validated process says otherwise.

Leaving the batch whole in the refrigerator: Portion, label, refrigerate what you will use soon, and freeze the rest.

A practical timeline

Day 1: Trim, weigh, calculate, mix, apply, bag, label, and refrigerate.

Days 2 through 6: Turn the bag once daily and confirm the refrigerator remains cold.

Day 7: Follow the tested recipe's completion check. Rinse, cook a taste slice, adjust surface salt only if needed, then dry uncovered in the refrigerator.

Day 8: Smoke with a clean indirect fire, cool promptly, and refrigerate.

Day 9: Slice cold, portion, label, refrigerate a seven-day supply, and freeze the remainder.

Exact cure time depends on thickness and the researched recipe. The timeline is an organizational model, not permission to ignore those details.

The bottom line

Good homemade bacon comes from boring precision followed by creative smoke. Weigh the trimmed belly. Calculate Prague Powder #1 in grams. Keep the meat at 40°F or below. Use the complete measured cure, allow enough refrigerated time, form a dry pellicle, and smoke with a clean fire. Then chill, slice, cook, and store it as a perishable pork product.

The non-negotiable warning is worth repeating: Prague Powder #1 contains sodium nitrite and is toxic in excess. Measure it by weight in grams only, never by teaspoon or by eye. Start every batch with the brine & cure calculator, verify the product label, and keep USDA FSIS handling guidance beside the recipe rather than treating safety as a final footnote.
