The hundred-year-old orchard at Orcas Montessori School provides a key ingredient for the school’s fall fundraiser.

This fall, the school is selling organic apple crisps under the direction of professional baker and chef Matt Carpenter.

Like the hot lunches served at the school, the apple crisps contain all organic ingredients, from the butter and oats to the sugar and cinnamon.

The crisps are sold frozen, ready-to-bake for $16 each. They can be purchased directly from the school by calling 376-5350.

They also will be available during the school’s holiday wreath sale.
