Makes 6 (3 x 4-inch) squares.
4 cups fresh BLUEBERRIES
1 cup fresh STRAWBERRIES, hulled
1/4 cup HONEY
1 Tbsp. ALMOND EXTRACT
Place blueberries and strawberries in blender and blend until smooth. Pour mixture through a strainer to remove skin and seeds. Stir in honey and almond extract. Place mixture in a large skillet. While stirring frequently, cook over very low heat for 1 hour until thickened. Line a cookie sheet with parchment paper or aluminum foil. Preheat oven to 150. Pour thickened mixture onto parchment paper and spread to form an 8 x 12 rectangle. Bake for 5 1/2 to 6 hours until the fruit sheet is dry enough not to stick to your fingers but moist enough to roll. Remove from oven and cool. Once cool, leather should be stored in an airtight container or rolled in plastic wrap to keep.
Note: (Placing a potholder in the oven door to keep it ajar will help dry the leather by allowing moisture to escape.)
