Half-and-Half Measuring FAQs

Can half-and-half be whipped into peaks like heavy cream? ▾

No, half-and-half only contains 10.5% to 18% fat, which is insufficient to form and sustain a whipped air foam.

Will half-and-half curdle when added to acidic soups? ▾

Due to its lower fat-to-protein ratio compared to heavy cream, it curdles more readily; add it over low heat at the end of cooking.
