In a mixing bowl, whisk together the soy sauce, brown sugar, black pepper, garlic powder, onion powder, red pepper flakes, Worcestershire sauce, and liquid smoke if using.

Taste the marinade and adjust sweetness or spice according to preference.

Slice your chosen meat into thin strips, about 1/4 inch thick.

Place the meat strips in a resealable plastic bag or glass container and pour the marinade over the meat.

Seal the bag or container tightly and refrigerate for at least 4 hours, preferably overnight.

After marinating, remove the meat from the marinade and let any excess drip off.

Dry the meat using a dehydrator, oven, or smoker at a low temperature.

Once dried, let the jerky cool before storing it in an airtight container.
