According to the guys I play poker with, these are the best burgers ever. I used a recipe posted here on the forum. This is the original recipe: http://www.smokingmeatforums.com/t/72690/smoked-burgers
I did at one ingredient:
2 lbs. ground beef
1/4 cup minced onion
1 whole large egg
2 tsp. chopped garlic
2 tbsp. Worcestershire sauce
1/2 tsp. ground black pepper
1 tsp. salt
1/4 tsp. nutmeg
** I add** heavy whipping cream to the meat mixture. Trust me. I don’t have a measurement for the amount, but maybe around ½ cup plus. You don’t want it too wet, but add as much as you think will work.
I stuff them with one slice of American cheese. It does not leak out as easily as other cheeses.
Mix all the ingredients together and form into patties smoke at 170 for one hour and finish up with a cabinet temp of 225 until the patties are around 170 degrees takes about 2 hours roughly I used hickory chips.
Also I made my own burger press. Went to Home Depot and purchased a couple of 4" PVC couplers and used them to make the press.
