Blueberry jam

Overview

For the sake of your children’s health, why not do it yourself? It’s actually very simple

One pound of blueberries, washed with water
grams of rock sugar, you can add more if you like it sweet, or you can use granulated sugar instead
Add a little water to the washed blueberries (you can add water or not)
Use manual gear one to slightly smash the blueberries
Place the beaten blueberries in a casserole, add rock sugar and cook over low heat. Stir constantly during this period to prevent the pot from sticking
After simmering for about an hour, the jam will become thick. Turn off the heat, cool and store in a sealed jar
