1 C Granulated Sugar
1/2 C Water
1/2 C Berries (fresh is best, frozen tends to be a bit tart)
Place the sugar and water in a medium saucepan over medium heat. Cook for 1 minute, stirring, until the sugar dissolves
Add the berries and cook until the berries break down, about 5 to 6 minutes, turning the heat to low when it starts to boil. Break down the berries with a spatula as needed. Once the berries are fully broken down, strain the syrup into a jar using a fine mesh sieve or strainer: use a spatula to force it through until all the seeds and skins (if any) are strained out
Allow to cool. It will thicken as it cools, then place in the fridge.
