Preheat oven to 375 degrees. Combine oats and almonds in a medium bowl. In a small saucepan, combine honey, molasses, water, vegetable oil and cinnamon. Heat through, stirring for about 1 minute. Pour over oat mixture and stir to blend. Spread on a baking sheet and toast, stirring every 10 minutes until golden-crisp, about 30 minutes. Remove from oven and add raisins. Cool completely before serving. Store in an airtight container for up to three weeks in the refrigerator or at room temperature.
