The easiest frozen blueberry jam
Ingredients:
- 1 kg frozen blueberries;
- 800 grams of granulated sugar;
- citric acid on the tip of a knife.
Preparation:
Pour the thawed and washed berries into a saucepan (if the blueberries are from bags, there is no need to wash them, because they have already been sorted and washed). Sprinkle the blueberries with sugar, stir well so that the berries release their juice, put on low heat, cook until boiling, stirring occasionally. Skim the foam from the boiled brew, turn off the stove, and leave the blueberry jam to cool. When cool, bring to a boil again, simmer over medium heat for 7-10 minutes, stirring frequently. Add citric acid at the tip of a knife. Pour hot blueberry jam into sterilized jars and seal. Can be covered with nylon lids.
Frozen blueberry jam without cooking
I won’t tell you about blueberries mashed with sugar. I prepare frozen blueberry jam without cooking using a completely different recipe.
Ingredients:
- 1 kg blueberries;
- 700 grams of sugar.
Preparation:
Wash the blueberries and sort them, then add sugar, mix thoroughly, and leave for half an hour. In the meantime, wash the jars, fill them first with hot water, then with boiling water. Heat the berries with sugar to a temperature of 70-80 degrees, immediately remove from heat. After 5 minutes, drain the boiling water from the jars and place the blueberries and sugar in a glass container. Place the jars in the oven, turn the oven on to 100 degrees and simmer the jars with berries for 20 minutes. Don't be afraid, with gradual heating the glass is not in danger. Remove the jars from the oven, using oven mitts to avoid burning your hands. Cover with nylon lids and store in the refrigerator. This jam retains more vitamins than traditional jam.
Five-minute frozen blueberry jam
Ingredients:
- 1 kg frozen blueberries;
- 800 grams of granulated sugar.
Preparation:
Thaw the berries and sprinkle them with sugar properly. You can even press down lightly with a spoon while stirring so that the blueberries release their juice faster. As soon as there is enough juice, start cooking. Bring the berry mass to a boil and cook for exactly 5 minutes. Cool, and while the jam is infused, process the jars (sterilization process). Stir for five minutes again, bring to a boil and after 5 minutes pour into jars. Screw or close with nylon lids.
