Combine 2 Tablespoons water and cornstarch in a small dish and set aside.

In a medium saucepan, bring water, sugar or honey, and blueberries to a boil. Stir occasionally. Reduce heat and simmer for about 10 minutes. Add water+starch mixture and blend well. The sauce will thicken, the blueberries will have busted open and it begins to smell like pie.

Store in refrigerator up to two weeks. Take out a few minutes before serving at room temperature or warm.
