Frog Hollow Farm is one of the best vendors at San Francisco's Ferry Building. Their organic, fresh fruit and all of the yummies they produce from it are amazing. They make dried fruit, preserves, tarts, pies, scones, muffins and ... scuffins, which is a cross between a scone and a muffin with "a surprise dollop of apricot conserve baked in the center." You can order their apricots, apricot conserve (preserve) and these scuffins on their website (see links 3 and 4 below). Scuffins also come in nectarine and peach flavors.
