Smoking and curing meat at home is among the most rewarding food preservation hobbies and one of the easiest to do wrong in a way that hurts you. The traditional methods evolved over centuries to manage the same pathogens that modern home cooks must still respect: Clostridium botulinum spores in low-oxygen environments, Listeria monocytogenes that grows even in cold conditions, E. coli in undercooked ground meat, and the general bacterial growth that happens at room temperature. The cure salt math, the smoke temperature distinction, and the internal cooking targets are not arbitrary rules; they are direct controls on specific microbial risks. This guide breaks down the safe practices for hot smoking, cold smoking, wet curing, and dry curing, with the specific numbers that separate a good batch from a dangerous one.
The cure salt math
Pink curing salt comes in two formulations. Both are dyed pink so they cannot be confused with table salt and accidentally used as seasoning.
Prague Powder #1 (also called Insta Cure #1 or Modern Cure): 6.25 percent sodium nitrite plus 93.75 percent salt. Used for products that will be cooked or smoked within days of curing: bacon, hot dogs, pastrami, smoked ham, jerky, brined poultry. The nitrite kills botulism spores and inhibits other pathogens during the curing period.
Prague Powder #2 (also called Insta Cure #2): 6.25 percent sodium nitrite plus 4 percent sodium nitrate plus 89.75 percent salt. Used for products that age slowly: dry-cured salami, prosciutto, country ham. The nitrate slowly breaks down into nitrite over weeks, providing extended protection during the long aging.
The standard ratio: 1 teaspoon of Prague Powder per 5 pounds of meat (4.5 grams of Prague Powder per 2.27 kg of meat), which delivers about 156 ppm of nitrite, the FDA maximum for cured meats. Never increase past this ratio. Nitrite is toxic in higher concentrations; the dilution into salt is exactly what makes home curing safe at this level.
The salt percentage in the overall cure is separately calculated, usually 2.5 to 3 percent by weight of the meat. So a 1 kg pork belly for bacon uses 25 to 30 grams of salt plus 2.5 grams of Prague Powder #1, plus sugar and seasonings as desired.
Hot smoking, the safer starting point
Hot smoking means cooking the meat at 225 to 275 F (the typical low and slow smoking range) until it reaches a safe internal temperature. The smoke flavors the meat; the heat cooks it. From a food safety standpoint this is the same as oven cooking with extra flavor.
Safe internal temperatures:
- Beef, lamb, pork (whole muscle), fish: 145 F with 3 minute rest
- Ground meats (burgers, sausages from raw): 160 F
- Poultry (any cut): 165 F
- Reheated cooked meat: 165 F
Use an instant-read thermometer. Smoker thermometers measure ambient air, not internal meat. The two numbers differ by 20 to 50 F in normal smoking. Buy a $25 digital instant-read (ThermoPro TP19 or ThermoWorks Thermapop) and check internal temperature in the thickest part of the meat, away from bone.
Hot smoke until internal temperature target is reached. Rest 10 minutes for small cuts, 30 to 60 minutes for large cuts (brisket, pork shoulder). Slice and serve, or cool and refrigerate within 2 hours.
Cold smoking, the advanced practice
Cold smoking means flavoring meat with smoke at temperatures below 90 F (some sources say below 80 F). At these temperatures the meat is not cooked. It is being seasoned with smoke compounds while remaining in the bacterial danger zone (40 to 140 F).
Cold smoking is only safe when the meat has been preserved by another method first:
- Heavy salt cure (bacon: salt-cured 5 to 7 days before cold smoking)
- Nitrite cure (Prague Powder #1 for products smoked then cooked, Prague Powder #2 for products smoked then aged)
- Lowering water activity below 0.85 (dry-cured meats)
- Lowering pH below 4.6 (fermented sausages)
Common cold smoked products and the preservation step:
- Cold smoked bacon: salt and nitrite cured 5 to 7 days, then cold smoked 8 to 24 hours, then refrigerated for use or hot cooked before eating
- Cold smoked salmon (lox): salt and sometimes sugar cured 24 to 72 hours, then cold smoked 6 to 12 hours, eaten as is (the salt cure plus refrigeration plus low pH from the cure is the preservation)
- Cold smoked cheese: cheese is already a preserved low-water-activity food, so cold smoking just flavors it
- Cold smoked sausage (for later cooking): nitrite cured, cold smoked, then either refrigerated for cooking or aged into dry sausage
Never cold smoke fresh raw meat without an explicit safety protocol. The risk of botulism or other illness is real.
Wet curing (brining)
Wet cure: meat is submerged in a salt-water-sugar-nitrite brine for days. The salt and nitrite penetrate the meat by diffusion. Sweet brines pull water in as well, plumping the meat.
Standard wet cure for bacon, ham, smoked turkey, pastrami: 1 gallon of water plus 1 cup of kosher salt plus 1 cup of sugar plus 1 ounce (28 grams, about 6 teaspoons) of Prague Powder #1. Cure time: 1 day per half inch of thickness, plus 2 extra days. So a 2 inch thick pork belly cures 6 days; a 4 inch ham cures 10 days.
Submerge meat fully in the brine in a food-grade non-reactive container (glass, food-grade plastic, stainless steel). Refrigerate the whole assembly at 36 to 40 F for the entire cure period. Use a weight to keep the meat under the brine. Stir or rotate the meat once a day.
After curing, rinse the meat well, pat dry, optionally rest in the fridge overnight to form a pellicle (sticky surface), then smoke or cook.
Dry curing
Dry cure: salt and seasonings are rubbed directly on the meat surface, no water added. The salt draws water out of the meat over days, the water carries dissolved salt back in, and the meat becomes preserved as water activity drops.
Standard dry cure for bacon (without water): 2.5 percent salt by meat weight, 0.25 percent Prague Powder #1, plus sugar and seasonings to taste. Rub thoroughly, place in a sealed plastic bag, refrigerate 7 days, turn the bag daily.
After dry curing, rinse the meat (or do not, depending on the recipe), dry the surface, smoke or cook as desired.
Dry aging (the salami category)
Dry aging is the long timeline category that takes products from raw meat to shelf-stable dry sausages over months. The protocol involves Prague Powder #2 (nitrate to nitrite over time), fermentation cultures to drop pH below 5.0, and a controlled aging environment of 50 to 60 F with 70 to 80 percent relative humidity.
This is the most advanced home charcuterie work. Equipment includes a dedicated curing chamber (often a converted refrigerator with controllers for humidity and temperature), specialty starter cultures, casings, and a meat grinder plus stuffer.
A beginner should not start with salami. Start with bacon, then move to pastrami, then to wet-cured ham, then to fresh sausage, then to fermented sausage, then to dry-cured sausage. The progression takes years and the failure modes get more dangerous at each step.
Storage of finished products
Hot smoked meat, no cure: refrigerate within 2 hours of cooking. Use within 4 days. Freeze for 6 to 12 months.
Cured and hot smoked (bacon, ham, pastrami): refrigerate. Bacon keeps 1 to 2 weeks unsliced, 5 to 7 days sliced. Smoked ham keeps 2 to 3 weeks. Vacuum-sealed and frozen: 6 months.
Cold smoked, cured (lox, traditional bacon): refrigerate. Lox keeps 5 to 10 days. Cold-smoked bacon keeps 2 to 3 weeks unsliced. Always cook cold-smoked bacon before eating.
Dry-cured products: store in the curing chamber or wrapped in butcher paper in the refrigerator. Whole salami keeps for months. Sliced products keep 1 to 2 weeks.

Frequently asked questions
Do I really need pink curing salt to make bacon or jerky?+
For wet-cured bacon, yes. The nitrite (Prague Powder #1 or Insta Cure #1) prevents botulism during the multi-day curing process and gives bacon its signature pink color and flavor. For jerky made under 24 hours that you eat within a week, no; the salt and the heat are sufficient. For long-cure products like dry-cured pancetta, salami, or country ham, you need Prague Powder #2 (which contains nitrate that slowly converts to nitrite over weeks).
What is the difference between Prague Powder #1 and #2?+
Prague Powder #1 is 6.25 percent sodium nitrite plus 93.75 percent regular salt, tinted pink to distinguish it from table salt. Used for products cooked or smoked within a few days (bacon, hot dogs, ham, jerky, pastrami). Prague Powder #2 is 6.25 percent sodium nitrite plus 4 percent sodium nitrate plus 89.75 percent salt. The nitrate slowly converts to nitrite over weeks to months, used for dry-cured products that age 4 to 12 months (salami, prosciutto, dry-cured sausages).
Is cold smoking dangerous?+
Cold smoking (below 90 F) holds food in the bacterial danger zone for hours or days. It is only safe when the meat is already preserved by salt curing, nitrite, low water activity, or pH below 4.6. Hot smoking (above 165 F) cooks the food during smoking and the safety risks are similar to oven cooking. Beginners should start with hot smoking. Cold smoking salmon, bacon, and cheese should be attempted only after research into the specific protocol for each product.
What internal temperature does smoked meat need to reach?+
The USDA-safe internal temperatures: 145 F for whole-muscle pork (with 3 minute rest), beef, lamb, fish, and ham. 160 F for ground beef and ground pork. 165 F for poultry. These apply equally to smoked or oven-cooked meat. Cure-based safety (Prague Powder, salt) allows for some flexibility on the temperature for cured products like bacon and ham, where the cure does the pathogen control, but the safe internal temperatures still apply to fresh non-cured meats that you smoke.
How long does smoked or cured meat last in the refrigerator?+
Hot smoked meat without curing: 4 to 5 days refrigerated, the same as cooked meat. Vacuum-sealed and frozen: 6 to 12 months. Cured and smoked products (bacon, ham, pastrami): 1 to 2 weeks refrigerated unsliced, 5 to 7 days sliced. Dry-cured products (salami, prosciutto): months in the original sealed cellar conditions, weeks in a refrigerator after slicing into. Always check for off odor and slime before eating older cured meat.
