Combine 1 cup vegetable juice like V8, ½ cup vodka, 1 tsp. each salt, black pepper, hot sauce, onion powder, and celery seed, 1 Tbsp. each lemon juice, horseradish, and Worcestershire sauce, 2 cloves crushed garlic, and ¼ cup olive oil. Marinate 1 pound flank steak in half the mixture for 8 to 24 hours. Simmer the remaining marinade in a saucepan until reduced by half and reserve, reheating right before serving. When you're ready to cook the steak, heat a grill pan or skillet to high. Wipe marinade off steak and sear both sides, then lower heat and cook until steak is medium rare, 8 to 10 minutes. Let rest for 5 minutes, then slice against the grain. Serve with the reduced sauce, a drizzle of olive oil, and chopped celery and tomato.
