Bay seniors know these August weeks are the time of year when we most heartily congratulate ourselves for living here. The late summer crop of swooningly sweet fruits is irresistible whether you’re picking them in your back yard, at farmer’s markets or, admit it, supermarkets. The gold standard for 20 years has been Frog Hollow Farms, especially their dozen varieties of direct-from-heaven organic peaches. Did you know you can order them online or that they have their own café in the Ferry Plaza? Although you can’t head out to their Brentwood acreage and pick them yourself, there are plenty of farms across this juicy state that welcome you. All these fruits are a simple hand-to-mouth pleasure, but they’re even more amazing when grilled.
