Sweet Mulberry syrup is excellent over pancakes, ice cream, and other foods. Here’s how to make it:
Mash one pint of berries in a cooking pot, add 2 cups of white sugar, and bring the mix to a boil for 10 minutes. No water is needed as the berries are juicy enough. Stir constantly to prevent burning. While the mix is still hot, pour through a strainer into a clean jar.
