I had a family friend of my Nana from Hungary make a dessert from blueberries before my eyes when I was 14.
Rinse and place blueberries in a saucepan. If they’re a bit tart, add 1 or 2 Tablespoons of sugar. Warm of medium heat until some of the berries pop, creating juice. Optionally, add 1 Tablespoon of lemon juice. Remove from heat and let cool. Serve warm or chilled with a large dollop of sour cream.
