As San Francisco heads into harvest season, local farmers markets are starting to fill with gorgeous fall produce. While you're perusing the squash options, don't forget to grab the last of some produce you won't see again until next summer.

Warren Pears from Frog Hollow

There are only two farms in California that grow Warren Pears, and Frog Hollow is one of them. The pears are a heritage hybrid that produce a sweeter and more intense taste with a greater depth of flavor compared to your typical green pear. Buttery, soft, and juicy in texture, the skin is smooth and has no grit. Find these beauties in salads at restaurants such as Chez Panisse, Nopa, and Tony's Pizza. // Saturdays at the Ferry Building Farmers Market,froghollow.com

Watermelon Radishes from Heirloom Organic Gardens

Watermelon radishes are traditionally planted after the summer solstice and are now being harvested. Crunchy in texture, and sweet and zesty in taste, watermelon radishes are great for shaving over salads or pickling for later. // Saturdays at the Ferry Building Farmers Market, heirloom-organic.com

Winter Squash from Capay Organic

Is there anything that screams autumn more than a table of pale yellow, dark green, and orange squash? We think not. This month, pick from an array of winter squash grown by Capay Organic, a family-run farm in Yolo County. The squash are grown on vines and are sun-cured after harvesting so that the skin hardens, allowing them to stay ripe for months. // Saturdays at the Ferry Building Farmers Market,capayorganic.com

Reed Avocado from Brokaw Nursery

If you don't already know about Brokaw avocados, now is the time to educate yourself: they're probably the best avocados you'll ever put in your mouth. Creamy, buttery, and extra fatty, even The French Laundry prefers them. Brokaws are never refrigerated and are sold at the farmers market no more than one day after bring plucked from the tree. October is the last month you'll be able to get these delicious beauties until late February—so stock up! // Saturdays at the Ferry Building Farmers Market,brokawnursery.com
