I've been making jerky from ground beef for a few years with great success. Get a good dehydrator (Nesco GardenMaster) and a jerky gun. Got mine at London Drugs, both on sale. The Jerky gun comes with a seasoning kit, but I did not find it very good. Here is the recipe I first found online then adjusted it to my liking:
Per Pound of extra lean ground beef:
1/2 cup China Lilly Soy sauce (I find this brand tastes the best, but to each their own)
1/2 tsp onion powder
1/2 tsp garlic powder
1 tsp salt
1 tsp coarse ground pepper
1 tsp brown sugar
1 tsp liquid smoke
1 tsp Worcestershire
… for abit of kick if you like (only makes it mildly hot)
1 tsp of Cayenne
1 tsp of Franks red hot
1 tsp Tobasco
I do 5 lbs (2500 grams) at a time. The dehydrator comes with 4 trays, but I bought an extra 2. With 6 trays, I can fit 5lbs perfectly. I think the amounts above are abit too much, so for 5 lbs I multiply the recipe amounts by 4, not 5. Mix up really well, cover with saran wrap and let sit in fridge for at least 12 hours. Takes about 4.5 hours dehydrating time.
