For the Filler: Cut steak into 1/4 inch cubes. Saute in non-stick pan with garlic, salt, and pepper. You can add oil or cooking spray. This saute only takes a few minutes as the steak chunks should be small. When that is complete, mix with cream cheese in a quart size bowl.
Batter: These are rough guidelines for a beer batter. Any recipe you may have that you like can be used. Mix dry ingredients according to taste in a medium sized metal mixing bowl. Add beer while mixing with a wisk until you reach the consistency of a thick pan cake batter.
Process: Heat deap fryer to 350 degrees with any kind of oil you desire. I recommend Crisco, vegetable, or Peanut oil. Stuff jalapeno's with filling and dip into batter with a spoon. Gently place into deep fryer. Only cook 5-6 at a time as you don't want the tempurature to drop drastically. Fry until golden brown, typically 5-6 minutes. Use slotted metal spoon to retreive. Let drain on paper towels.
