Tissue-thin phyllo pastry encloses a mixture of ricotta, golden raisins, and portobello mushrooms.
Wrap ricotta tightly in fine cheesecloth; place in a colander over a bowl. Place a heavy bowl or cans on top; let drain, refrigerated, for 3 hours or overnight.
Heat oven to 350 degrees. Place almonds on a baking pan; toast until fragrant, about 6 minutes. Transfer from oven to cool, then break almonds into small pieces; set aside. Place raisins in a bowl, cover with 1/4 cup warm water, and set aside.
Heat a large saute pan coated with olive-oil cooking spray over medium heat. Add garlic and onion; saute until translucent, about 5 minutes. Add mushrooms; cook until tender and juices are released, about 3 minutes more. Add raisins, soaking liquid, salt, cinnamon, cayenne, and cumin; cook until the liquid has been absorbed. Stir in balsamic vinegar, and transfer to a medium bowl to cool. When fully cool, about 25 minutes, stir in chopped parsley.
Place phyllo on a dry work surface; cover with a slightly damp towel. Coat one phyllo sheet with cooking spray. Cover with a second sheet; coat with cooking spray. Place a third sheet on top; cut stack into four 4-by-12-inch strips. Place 1 tablespoon ricotta on bottom of each stack; spread into the left corner to form a small triangle. Top with 2 tablespoons mushroom mixture. Fold phyllo by bringing bottom left corner over to meet right edge of pastry. Fold triangle along strip to fully enclose filling. Place on a parchment-lined baking pan. Repeat with remaining phyllo and filling. Coat triangles with cooking spray; sprinkle with reserved nuts. Bake until golden, about 40 minutes, rotating halfway through cooking. Serve.
These pastries are ideal as a part of a buffet.
