At Mission Pie in San Francisco, the teen serving up your pie slice and cappucino may have picked the pie’s berries and perhaps fed the chicken that laid the eggs for another pie’s custard. Only a few months old, the pie cafe is part of the mission of the owners of Pie Ranch, a pie-slice shaped farm in Pescadero. Inner-city students regularly visit Pie Ranch to help with chores, see where food comes (or should come) from, and, of course, learn to make pie. At Mission Pie they learn to serve customers, make cappucino, and, when a new kitchen opens, they’ll make more pie. The teens are also learning about nutrition and the benefits of using local food suppliers.
