In a medium sauce pot, mix together Fresh Strawberry (8 ounce), Fresh Blueberries (1 pint), and Blackberries (1 pint). Add Granulated Sugar (4 ounce), zest of the Lemon (1), and the Lemon Juice (1 splash). Stir together to evenly coat the berries in sugar.
Bring berries up to medium heat and cook until juices leech out of berries. Cook berries until the juices have fully leached out, and the berries are super soft. If you want it thicker, whisk 1Tbsp of water with 1Tbsp of cornstarch and mix.
Store in an airtight container for up to 7 days. Enjoy!
