Over a medium heat saute shallots, leeks and andouille sausage in oil. When leeks and shallots turn translucent add the hot sauce, Worcestershire sauce and lemon juice. Reduce by half. Add the 1/2 cup white wine and tomato puree and reduce. Add the shrimp and saute until cooked. Remove from heat and stir in 2 tablespoons of butter. Season with salt and pepper, to taste.
