Add ground beef to a large bowl along with salt, pepper and Worcestershire sauce

Use your hands to smush and mix it all together

Form the mixture into 12 small patties, then make a well in the center with your thumb. This will keep the patties from plumping too much when they are cooked.

Heat the butter in a large skillet over medium-high heat, then cook the patties on both sides until they are almost done in the middle

Remove the patties from the skillet and keep them on a plate, then throw the diced onion into the skillet and stir them around to cook, 2 to 3 minutes

Next, pour I. the whiskey! (If you are cooking over an open flame, cutoff the burner long enough to pour in the whiskey, then turn it back on.)

Stir the whiskey and let it bubble up and reduce by half, 1 to 2 minutes.

Reduce the heat to low, then pour in the barbecue sauce

Next, add the jalapenos to the skillet and stir them around. Splash in a little juice from the jalapeno jar for more heat and flavor

Add the patties back into the skillet and use a large spoon to coat the top of the patties in the sauce. Let it simmer for 5 minutes, or until the sauce is bubbling and the patties are totally done in the middle

Remove the patties and serve them on the rolls, spooning extra sauce over the top of the patties
