Satan's Blood does this for me. Not really a sauce, more an additive. I'll usually do one drop to a large bowl of Chili for myself. It gives the throat hit. Be real careful handling it though. I wear gloves and still wash my hands and the bottle after. For a lightweight a toothpick tip dipped in it and mixed in their food is enough. Even a toothpick tip across a hotheads tongue will light you up pretty good. https://www.amazon.com/Satans-Blood-Chile-Extract-Sauce/dp/B007P643GE
