Ingredients For Potato Waffles Recipe
Mashed potatoes: These form the base of the waffles, providing a creamy texture and rich flavor.
All-purpose flour: This helps to bind the ingredients together and gives structure to the waffles.
Eggs: They add richness and help to hold the batter together.
Milk: This adds moisture to the batter, making the waffles tender.
Baking powder: This leavening agent helps the waffles rise and become fluffy.
Salt: Enhances the flavor of the waffles.
Green onions: Adds a fresh, slightly pungent flavor that complements the potatoes.
Technique Tip for Potato Waffles
To achieve the perfect texture for your potato waffles, make sure your mashed potatoes are smooth and free of lumps. If your mashed potatoes are too thick, you can thin them out with a bit of milk before mixing them with the other ingredients. This will ensure an even batter and a consistent cook throughout the waffle. Additionally, don't overmix the batter once you add the flour and baking powder; overmixing can result in tough waffles. Finally, for an extra crispy exterior, allow the waffles to cook a little longer than usual, keeping a close eye to prevent burning.
