2In a medium saucepan, combine the Black Mulberries, Granulated Sugar, and Water. Bring the mixture to a gentle simmer over medium heat, stirring occasionally, until the Black Mulberries soften and release their vibrant juices, which typically takes about 10 to 15 minutes.
3Carefully pass the cooked mulberry mixture through a fine-mesh sieve set over a bowl. Press firmly on the solids with a spoon or spatula to extract all the juice and pulp. Discard the remaining seeds and skins from the sieve. You should now have a smooth, intensely colored mulberry juice.
