Salsa : help with title

help with title

ive been looking for this movie forever and i need someone to help me find it. The premise starts off alot like this movie except these two guys works as cooks and make a love potion out of a ketchup looking red sauce. The sauce makes people go crazy at parties/fall in love/become horny and the guys make big vats of it in their kitchen. it was made in the late 80's/early 90's. the love intrest was named ursula (same name as the witch from the little mermaid) and one of the guys gives her a thumb ring. please help. also, i think all the actors are latino in the movie but im not sure.
