1. Combine the dry ingredients in a bowl. Pour the butter and water over the mixture, stirring constantly to ensure everything is evenly coated. It is okay if the mixture is a little lumpy.
2. Spread the granola in a roasting pan lined with baking parchment. Dry the granola in the middle of the oven for approx. 1 hour and 15 min. at 300°F, stirring occasionally.
3. Take care that the edges don’t turn too brown. Let the granola cool before adding the raisins.
4. Serve the granola with yogurt or your favorite breakfast dairy product.
The granola can be stored in a glass jar with a lid in the refrigerator for approx. 1 week.
