Okay, I neglected to read the entire recipe before I began and here I am now trying to have fish tacos CRIVINS! homemade crema. The recipe called for 1 cup half and half, 1 cup heavy cream and 1 tablespoon sour cream. I didn't read the part where it said the mixture needed to sit 24 hours at room temperature to culture. I don't have 24 hours, so I am wondering is there a way to thicken this stuff up quicly?
Your help is much appreciated.
