Buttermilk Ice Cream Base

Lush, velvety, and unapologetically rich. This buttermilk ice cream base brings the tang. With a custard backbone (hello, egg yolks) and a subtle twang from the buttermilk, it’s the perfect canvas for fruit swirls, cookie crumbles, or anything that begs for drama. Smooth, scoopable, and totally addictive.
