In a bowl, whisk together the flour, cornstarch, cayenne, egg and beer until just combined. Don't worry if there are clumps in the batter.

Preheat the oven to 200 degree F. Fill a large heavy bottomed pot with oil and heat to 350 degrees F. Set a large wire rack on a rimmed baking sheet and place near the stove.

Working in batches dip the onion rings through the beer batter and then carefully add to the hot oil. Deep fry the onions until golden brown and crisp, about 3-4 minutes. Using a wire skimmer, remove the onions from the oil and place on the prepared wire rack. Transfer the onion rings to the oven while you fry them remaining rings.

Sprinkle with salt before serving and serve warm atop the sliders!

Divide the meat into 6 balls and pat into smaller slider size patties. Add the buttermilk to a shallow bowl. To another shallow bowl, add the cornflakes, Panko, flour and cajun seasoning.

Working in an assembly line, dip the patties, one at a time through the buttermilk and then dredge through the cornflakes, coating the patties completely. Place breaded patties on a plate and repeat with the remaining patties.

Heat a large skillet over medium high heat and add a drizzle of olive oil. Once the oil is sizzling, add the burgers and cook until golden brown and cooked through, about 3-4 minutes per side. During the last few minutes of cooking, add the cheddar cheese to each burger.

To serve, place a burger on a warmed bun and drizzle with the black pepper rub sauce (recipe below). Top with onion rings and serve with ranch.

In a medium bowl combine the melted butter, hot sauce, cajun seasoning and black pepper. Whisk to combine.
