Our favorite pantry secret stays in your freezer. Compound butters are flavored with fresh herbs and spices, rolled into logs, and kept cold to retain all their flavor. We'll make a Garlic Thyme Butter, a Basil Chive Butter for steak, bruschetta or corn, and a Bagna Cauda Butter for fresh clams and pasta. And we'll visit some of the architectural gems of the Napa Valley.
