Apple. Pumpkin. Mincemeat. Pies in all their forms are a part of many peoples’ celebrations and holiday traditions, and the flakier the crust the better. Those who are fans of the pastries can take their palates out to play at the free Holiday Pie Tasting at the Petaluma Pie Company in Petaluma. Tastings will be held on December 7 and 14, noon–3 p.m. See facebook.com/petalumapiecompany for more information.
