Wash and cut the apple into small pieces. I don’t peel the apple as the skin has some good fiber (I buy organic for this matter). But you can peel it if you want.
Rinse the fresh blueberries thoroughly under cold water and remove any stems.
In a saucepan, combine the fresh blueberries and diced apples along with a tablespoon of water. I like to start with just one tablespoon of water, as the blueberries will release their own juices as they cook.
Add a squeeze of lemon juice; this is optional, but I think it adds to the flavor of this recipe.
Cook over low heat and bring the mixture to a simmer. You will see the blueberries start to break down and release their juices.
Stir to prevent the mixture from sticking. This will also help break down the blueberries.
Simmer for about 10 minutes, or until the blueberries are soft and apples are cooked but still firm.
Taste and adjust the sweetness, if necessary. I generally find I like it as it is but it usually depends on the sweetness of the fruit. If I feel like adding some, I add two or three drops of all-natural stevia.
Remove the compote from the heat and let it cool.
Once cool, transfer to a clean jar and store it in the refrigerator for up to a week.
Serve it warm, at room temperature, or cold from the fridge.
