Marinate the meat (optional). Use a solution of olive oil and vinegar sea salt, or a recipe of your preference. If you choose to marinate the meat, place in the refrigerator for 10 - 24 hours so that the beef can absorb the flavor. This step is optional; the additional moisture can make dehydration take longer and the resulting jerky may be stickier. Brown sugar is a great addition.
Add some unusual flavors to your jerky by adding some pineapple juice (Hawaiian jerky); some ginger (Asian jerky); or some curry powder (Indian jerky). Don't be afraid to experiment!
