Instructions
Cut and Soak the venison Liver
Cut the liver into four equal-sized pieces. They should resemble a petit steak.
Soak liver pieces in the buttermilk for 2 to 4 hours. This removes excess blood and helps mellow the flavor. Make the onion aioli while the liver is soaking.
Make the Onion Aioli
Heat a heavy-bottomed skillet over medium heat. Add oil and onions. Cook, stirring frequently, until browned and tender. Add a little more oil if the onions appear too dry.
Reduce the heat to medium-low and stir in garlic, rosemary, and thyme. Cook 2 minutes.
Season with salt and pepper. Add vinegar, honey, and butter. Stir and cook until the liquid has evaporated. Remove from heat and let cool.
Transfer the onion mixture to a blender or food processor. Add mayonnaise, Dijon mustard, and a dash of hot sauce. Blend until smooth. Adjust seasoning to taste. Set aside.
Cook the Liver
Discard the buttermilk and rinse lightly with cool water. Pat completely dry with paper towels.
Season with salt and black pepper. Dust lightly with flour on all sides.
Working in batches. Heat ¼ inch of oil in a heavy-bottomed skillet over medium-high heat. Add the liver to the plan. Cook for about 3 minutes per side, or until the liver reaches a medium doneness.
Set to the side and let the liver rest while you fry the onions.
Make the Onion Rings
Heat oil in a small deep pot or cast-iron skillet to 325°F.
In a bowl, whisk together the tempura mix and chilled sparkling water. Drop in one ice cube to keep the batter cold.
Dip onion slices into the batter and fry in batches for 4-5 minutes, or until golden brown.
Remove and drain on paper towels. Season with salt and pepper.
Serve
Slice the liver into 1/4 in strips.
Place the onion rings around the liver. Drizzle the caramelized onion aioli over the liver and onion rings. Season with fresh herbs.
For the perfect bite, place all of the dish components on your fork and enjoy.
NOTES
Soak the liver first. Cut it into thick steaks and soak it in buttermilk for 2 to 4 hours to pull out blood and mellow the flavor before cooking.
Pat it very dry. After soaking, rinse lightly, dry it well with paper towels, season with salt and black pepper, and dust it lightly with flour so it sears instead of steams.
Do not overcook it. Sear the liver over medium-high heat for about 3 minutes per side, just until medium doneness. Venison liver goes grainy and bitter fast if you push it too far.
Cook in batches. Do not crowd the pan or you will lose the crust. Use a heavy skillet with about 1/4 inch of oil and fry only as much as fits comfortably at one time.
Keep the onion batter cold. Mix the onion ring batter with chilled sparkling water or beer and keep it cold with an ice cube, then fry the onion rings at 325 F until golden brown.
Make the aioli ahead. Cook the onions until browned and tender, finish with the vinegar, honey, butter, herbs, and garlic, then blend with mayo, Dijon, and hot sauce. It can sit while you cook the liver and onion rings.
Serve it right away. Let the liver rest briefly, then slice it into strips and serve it hot with the onion rings and onion aioli. This recipe tastes best fresh and does not reheat well.
