I like special homemade extra hot hot sauce, made from the Red Savina Pepper (which has an average Scoville rating of about 300,000) or as of recently with the Derset Naga Pepper (which has a Scoville rating of about 1,000,000). Just to but that in terms standard Tabasco red pepper sauce rates at only 2,500–5,000.
I put it in or on just about anything tho, pizza, chilli, taco's, etc. I love my hot sauce :3
