Use fresh, ripe strawberries for best flavor. Frozen strawberries can be used if thawed and drained well. Don’t overmix the batter to keep waffles light and fluffy. Preheat waffle iron fully for even cooking and golden color. Adding a tablespoon of cornstarch to dry ingredients helps with crispiness. Keep cooked waffles warm on a wire rack in a warm oven. Leftovers store well in the fridge for 3 days or freezer for 2 months.
