Frog Hollow Farm mainly is in the business of selling fruit. Beautiful pears, peaches, apples, nectarines, plums, and grapes come from their 120-acre organic farm on the Sacramento River Delta. You can buy the fruit at the Frog Hollow Market in the Ferry Building, and its freshness puts waxy supermarket fare to shame. The market also sells pastries made from the fruit: turnovers, galettes, tarts and tartlets; and while we never have had one that didn't cause us to moan with ecstasy, the cherry tartlet is nothing short of orgasmic. A delicate sheath of buttery pastry hugs fruit that is extremely sweet and extremely tart, the antipodes generating unspeakable excitement among taste buds coaxed to do their damnedest.
