Tart blueberries and plump zesty lemons are cooked down into a Blueberry Lemon Refrigerator Jam that will make your summer delicious!
Oh, how I love me some refrigerator jam! There is absolutely no fear with pressure cookers and canners. You make your jam, you ladle it in a jar, and when it cools you put it in the fridge. It is that simple.
This Blueberry Lemon Refrigerator Jam is one of my absolute favorites. Blueberries are everywhere these days. There is no excuse. You can make this!
Why you’ll love this recipe:
- Uses garden fresh blueberries.
- No canning needed! The refrigerator will preserve this jam for up to a month.
- Sweet juicy tartness of blueberries and the zesty brightness of lemon pair together in a delicious way.
- Perfect as a topping biscuits, pancakes, sourdough toast or lemon blueberry muffins.
Is refrigerator jam the same as freezer jam?
Freezer jam (such as our peach freezer jam) is made with fresh fruits that are barely cooked in order to preserve color and flavor. This refrigerator jam is more of a traditional jam that starts with fresh fruits, but is cooked down lemons and sugar to thicken. It stores well in the refrigerator, but you could also freeze it to keep it longer.
How to Make Blueberry Lemon Refrigerator Jam
Refrigerator jam isn’t hard to make at all, but it does take some time since you need to watch the fruit closely as it cooks. You don’t want it to scorch.
- In a large saucepan combine blueberries, sugar, lemon zest and juice, vanilla bean paste, and water. Cook over medium/high heat bringing the mixture to a boil for about 5-7 minutes or so. At this point there should be a decent amount of liquid coming from the blueberries. Reduce the heat to low and continue cooking over low heat stirring every few minutes or so to ensure the mixture does not stick to the pot.
- Cook until the liquid has reduced, thickened, and blueberries are very soft. This will take anywhere from 45-50 minutes. Remove from heat and allow to cool for about 10 or 15 minutes or so. The jam will thicken as it cools.
- At this point you can either blend it until smooth or leave as is. I like my jam with pieces of fruit, so I leave as is.
- Ladle the warm jam into mason jars. Place lids and rings on top and tighten to seal the jars. Allow the jam to come to room temperature before placing them in the refrigerator.
