Pique sauce

Pique is a Puerto Rican hot sauce commonly found at restaurants and roadside stands. Homemade versions of this type of sauce are made by steeping hot peppers in vinegar, with seasonings and fresh herbs. One popular variant is habanero peppers with pineapple and fresh recao leaves. The longer it sits, the hotter it gets.
Different types of Island ajíes picantes (hot peppers) will have varying amounts of heat, the hottest of all is the ají caballero.
