Quick Answer
To test jerky doneness, use a food thermometer to check the internal temperature, or check for flexibility and dryness by cutting into a piece of jerky.
Visual Inspection and Cutting Test
Visual inspection and the cutting test are effective methods for checking jerky doneness. Hold a piece of jerky up to the light to check for transparency, and look for a deep red or brown color. If the jerky is still too moist, it will not be transparent. Use a sharp knife to cut into a piece of jerky; if it cuts easily and springs back slightly, it’s done. If the jerky is still too chewy or soft, continue drying it.
Temperature Test
The most reliable method for testing jerky doneness is using a food thermometer. Insert the thermometer into the thickest part of the jerky, avoiding any fat or connective tissue. The internal temperature should reach 160°F (71°C) for beef, 160°F (71°C) for venison, and 145°F (63°C) for chicken or turkey. If the temperature is lower than this, the jerky is not yet done.
Timing and Patience
Timing and patience are crucial when making jerky. It’s better to err on the side of caution and dry the jerky a bit longer than to risk under-drying it. Over-drying can be corrected by rehydrating the jerky, but under-drying cannot be fixed. Aim to dry the jerky for at least 3 to 4 hours at 160°F (71°C), and check it every 30 minutes for doneness.
