These sweet, tangy, nutritious fruits grow wild in abundance throughout the northern regions of the U.S. They're great by themselves, mixed in with breakfast cereal or embedded in pancake batter, and now with this recipe you can spread them on your morning toast!
2 quarts blueberries, rinsed and drained
3 tbsp lemon juice (optional)
