The main ingredient in apple pie? Apples, of course.

Do you make a great apple pie? Would you put yours up against any other pie in the known universe? Or at least your neighborhood? Perhaps you should enter Sunday’s Apple Pie Contest at the Sebastopol Farmers Market. It’s simple to do: Just make your pie and bring it to the market before 11 a.m. Sunday morning and you’re in. The maker of the winning pie will walk away in a crown designed by Nikki of Earthworkers Farm, who is also knitting ribbons for runners-up. There will be other prizes, too, including market bucks.

The contest is part of the market’s celebration of the Gravenstein apple, which is being honored throughout the Bay Area this month.

On Sunday, the market will have an apple press with a free-tasting of just-pressed juice, apple-related activities for kids, information about Sebastopol’s beloved apple and much more. Dominique Cortara of Dominique’s Sweets will be selling her apple pies, too.
