Use fresh or frozen berries. If using frozen, do not thaw. Just increase cooking time.
2 tablespoons unsalted butter
¼ to ½ cup sugar
¼ teaspoon nutmeg
2 cups blueberries
Juice and zest of one lemon
2 teaspoons cornstarch
Splash of Grand Marnier or other orange liqueur (opt)
In saucepan, cook butter, sugar, nutmeg and blueberries over low heat until mixture starts to boil and blueberries start to pop. Meanwhile, combine lemon juice and cornstarch. Whisk into blueberry mixture. Cook on low until thickened. Add liqueur and blend well.
