Sure, presents are great, but what really makes the holidays a shared experience is food. But don’t just settle for the typical green-bean casserole and eggnog. On Sunday, Diesel Bookstore (5433 College Ave., Oakland) will host a Winter Cookbook Extravaganza to help you add some gastronomic creativity into your holiday festivities. Cookbook authors Lauri Pastrone, Allison Arevalo, Erin Wade, and Emma Christensen will be dropping by to share some of their recipes, including those for home-brewed kombucha, Kosovan sticky donuts, mac ’n’ cheese, and more. Join these Bay Area chefs to see how you can spice up your holiday this year.
