Strawberry & Blueberry Jam

Overview

The sweet and sour taste embellishes the happiness in life.

Wash the strawberries, remove the stems, drain, then cut in half and set aside.
Add the cut strawberries, blueberries, rock sugar, and lemon juice, mix well, and place in the refrigerator for more than 4 hours, or overnight.
Pour the ingredients into the pot, cook over medium heat, bring to a boil, turn to medium to low heat, and stir occasionally. At the beginning, there will be a lot of white foam, which must be removed. It will take about 30-40 minutes for the sauce to thicken.
Can immediately while hot and invert to cool. Can be kept refrigerated for 6 months.
