Blueberry jam

Cookinero 11 January 2023

Blueberry jam is a delight for every sweet tooth! Nice texture with whole berries, rich color, exquisite aroma with a light citrus note... Well, as for the taste, there is nothing to say, it's better to just make blueberry jam and try it. Remember that in this case the rule that applies to any jam works: try to use the freshest berries possible. For example, if you brought blueberries from the forest, do not put off processing them until tomorrow: after a few hours, the berries will give juice, which will not have the best effect on the quality of any of their dishes.

Blueberry jam - FAQ About Ingredients, Baking Time and Storage

The lemon adds brightness and helps with setting, but you can omit it if needed. A dash of citric acid or vinegar can mimic its acidity if desired.
