Quick answer
Yes — curing salt belongs in jerky. Cure #1 (6.25% nitrite) at the standard 156 ppm target works out to 1.13 g per pound of sliced meat (2.5 g per kg), mixed into the marinade before drying. Tender Quick follows its own 1-tsp-per-lb logic at roughly 63 ppm nitrite. Curing is not a substitute for the heat step: USDA jerky guidance still requires the strips to reach 160 °F (71 °C) — 165 °F for poultry — either during or after drying. Cure handles the formulation; the validated heat process handles lethality.

Assumptions, units and limits
- Basis is the raw, sliced meat weight — before marinade absorption. The cure dose is computed against the meat, not the marinade volume.
- 156 ppm is the U.S. ingoing reference for comminuted products and the common jerky target; 200 ppm is the general cap for many other products (9 CFR 424.21).
- Curing ≠ lethality. USDA jerky guidance requires the meat to reach 160 °F (71 °C) — 165 °F (74 °C) for poultry jerky. Follow the validated heat step in your recipe.
- This tool calculates formulation math only and cannot verify your product's actual composition — verify the label every time.

Why jerky needs curing salt at all
Jerky’s drying process removes water activity, and its heat step addresses vegetative pathogens — but Clostridium botulinum and several other risks are managed by the ingoing nitrite in the cure, especially during any low-temperature or come-up-time phases when the meat is still moist. Curing salt also delivers the familiar cured flavor and color that distinguishes jerky from dried cooked beef. That dual role — a measured formulation input plus a process-support ingredient — is why jerky recipes specify Cure #1 by weight and why “just dehydrate it” is not the same recipe.
Jerky cure amounts by batch size (156 ppm, 6.25% label)
| Raw sliced meat | Cure #1 (grams) | ≈ tsp | Nitrite delivered |
|---|---|---|---|
| 1 lb (454 g) | 1.13 g | 0.20 tsp | 71 mg |
| 2 lb (907 g) | 2.27 g | 0.40 tsp | 142 mg |
| 3 lb (1.36 kg) | 3.40 g | 0.60 tsp | 213 mg |
| 5 lb (2.27 kg) | 5.66 g | 0.99 tsp | 354 mg |
| 10 lb (4.54 kg) | 11.33 g | 1.99 tsp | 708 mg |
| 1 kg | 2.50 g | 0.44 tsp | 156 mg |
| 2 kg | 4.99 g | 0.88 tsp | 312 mg |
Jerky batches are small, and the doses are tiny — a 2 lb batch needs 2.27 g, well under half a teaspoon. This is the use case where a 0.01 g pocket scale (or the premix technique from that guide) stops being optional and becomes the difference between a formulated batch and a guess.
How to add the cure: marinade workflow
- Weigh the raw sliced meat and record it — this is the calculation basis.
- Dissolve the weighed cure (and the recipe’s salt/sugar/spices) into the marinade liquid. Cure distributes evenly through the liquid, which is more forgiving than a dry rub at these small doses.
- Marinate under refrigeration for the recipe’s time (commonly 6–24 hours), turning or vacuum-tumbling to keep every strip wetted.
- Dry per the recipe/dehydrator manual, then confirm the heat step: strips must reach 160 °F (71 °C) internal — 165 °F (74 °C) for poultry — with USDA guidance supporting either pre-heating or post-drying heating in the oven.
- Cool, condition, and store per the recipe: conditioned jerky bends and cracks without snapping; storage in airtight containers away from light, with whole-batch moisture checks (look for condensation in the bag on day two — a sign to refrigerate and use promptly).
Tender Quick for jerky?
Recipes written for Tender Quick exist — its 1 tsp per lb direction delivers roughly 63 ppm nitrite plus 63 ppm nitrate. If your recipe is written that way, follow it and check the numbers in the Tender Quick calculator. Do not convert a Cure #1 recipe to Tender Quick by scaling spoons — the salt and sugar the blend carries change the whole marinade balance. And the heat step still applies: no curing blend replaces the validated 160 °F process.
Common jerky curing mistakes
- Dosing cure by “a pinch per pound” — at jerky batch sizes the doses are sub-gram; guesswork at this scale is mathematically uncontrolled.
- Forgetting the basis is raw weight — weighing strips after partial drying undercounts the meat mass and over-doses the cure.
- Treating the cure as the food-safety step — the heat treatment is mandatory regardless of formulation.
- Marinating on the counter — cure or no cure, marinades belong in the refrigerator.
- Skipping the label check — a 5% blend needs 25% more product than a 6.25% blend for the same target.
Frequently asked questions about curing salt for jerky
Do I need curing salt for jerky?
Most tested jerky recipes include Cure #1, and it does two jobs nitrite-specific: formulation protection during the moist phases and the cured flavor/color profile. Whether your particular recipe needs it is the recipe’s call — but if the recipe lists it, the amount is not optional and not a garnish. Fresh-style dried-meat recipes that omit cure exist and are a deliberate product choice, not a shortcut.
How much Cure #1 per pound of jerky meat?
1.13 g per pound (2.5 g per kg) at the 156 ppm target with a 6.25% label — the same math as any other whole-muscle cure, computed on the raw sliced weight before marinating. The calculator above converts it for your exact batch and label.
Can I use Cure #2 for jerky?
No. Jerky is cured and consumed on a short timeline — there is no weeks-long aging for a nitrate reservoir to serve — and the blend would add nitrate the recipe has no use for. Jerky calls for Cure #1-style nitrite blends. The Cure #1 vs #2 guide explains the timeline rule.
Does curing salt make jerky shelf-stable?
Curing is one factor among several: drying to the right water activity, the validated heat step, and proper storage do the preservation work together. Cured jerky still molds if conditioned poorly or stored humid, and under-dried jerky is a risk regardless of formulation. Treat the cure as the recipe’s formulation input, not a license to relax the process.
Why does my jerky recipe’s cure amount look “too small”?
Because 156 ppm is a small number: 71 mg of nitrite per pound, delivered in 1.13 g of blend. Doses this small look wrong to eyes calibrated for tablespoons of soy sauce — which is exactly why they are weighed to 0.01 g rather than guessed, and why the calculator shows the milligram nitrite math behind every gram figure.
