Lamb and Beef Sliders with Beer Onions, Smoked Cheddar, and Horseradish Cream Sauce

Every man, woman, and child should be able to improvise a good burger recipe. Or you could make your friends think you're improvising by memorizing this powerhouse slider recipe. I literally surprised myself (and my roommate) with how good these were. Here's how to make it rain....

Ingredients:
1 lb each ground lamb and ground chuck
1 large sweet onion
3 tbls vegetable or grapeseed oil
2 tbls butter
2 tbls horseradish
1 cup sour cream
1/2 cup Red Ale
8 thick slices of smoked cheddar cheese
kosher salt and black pepper
8 Slider Buns

For the onions:
1. Heat the vegetable oil in a skillet on medium high.
2. Slice the onion and add to the skillet after it heats up. Cook for 5 minutes, stirring frequently so the onions don't burn.
3. Add the butter, some salt and pepper, and keep stirring. After another 5 minutes, add the beer and lower the heat to medium. Keep the onions cooking for another 10-15 minutes until they are brown and soft.

For the horseradish sauce:
1. Mix together the horseradish, sour cream, and some salt and pepper. Boom. Done.

For the burgers:
1. Preheat your grill to medium-high heat
2. In a mixing bowl, combine the ground lamb and chuck with a tablespoon of salt and some black pepper.
2. Form patties that are about a half-inch bigger than your slider buns - probably a quarter pound of meat for each burger.
3. Throw them on the grill, cooking each side for 3-5 minutes. In the last two minutes, put the smoked cheddar slices on each burger and close the lid of the grill.

Now you can form each burger. I leave it up to you how you want to stack the layers of flavor. We put burger, onions, then sauce, and stacked 'em nice and high. Let us know if you like this and any other variations you might ponder.
