Perfecting the Base
Start with perfectly cooked sweet potatoes for a smooth, lump free texture. Roast or boil the tubers until fork tender, then mash with butter, salt, and a touch of water or dairy free milk to reach your desired consistency.
For added depth, mix in freshly squeezed citrus, warm spices like cinnamon and nutmeg, and a stabilizer such as eggs or cornstarch. This creates a sturdy yet tender base that holds its shape when sliced and supports your chosen gluten free topping.
