Local chef, food writer, and culinary instructor Samin Nosrat is doing another of her popular series of new-school “Home Ec” classes just in time for the holidays. In three sessions she’ll cover the fundamental elements of good cooking: acid, salt, fat, and heat. The first class, on the proper use of salt, begins October 28 at 18 Reasons, and the whole series costs $325 — each class includes a dinner you’ll cook together, and wine. Reserve your spot here.
