Homemade butter is one of the most delectable ways to savor the grassy, sweet flavors of fresh cream. And you don't need to crank a wooden churn to do it. A simple new tool, Chef'n Buttercup Butter Maker ($15; chefn.com), shaves the time to a few minutes. Just add room temperature heavy cream to the butter maker and shake vigorously for about 3 minutes, until pale yellow curds separate from the liquid. Use the built-in sieve to strain off the buttermilk, and rinse the curds with cold water before they settle into the attached ramekin. Now fold in flaky sea salt, herbs, or whatever else you're into.
