Whisk with a fork until combined.
Divide the mixture between two 8oz mason jars or glasses.
Cover and refrigerate at least 4 hours or preferably overnight to set.
To Make The Blueberry Compote:Heat the berries in a small saucepan with the lemon juice over medium heat and bring to a simmer.
Cook and stir the fruit for 1 minute, lightly mashing the berries until slightly thickened. It should coat the back of a spoon.
