Sure, there's only really one hot week out of the year, but of course the Bay Area would be home to some serious ice cream; Marianne's - chocolate malt with a buttermilk base, Mitchell's - halo halo flavor, the It's It oatmeal cookie and mint chip sandwich. For artisan flavors inside the foggy city proper, look to the salted burnt caramel at Bi-Rite or the infamous pepper(as in black peppercorn)-mint ice cream at Humphrey Slocombe, both crafted from a base of Straus milk ice cream that comes from Tomales Bay happy-California cows.
