What I did when I have some sweet potatoes at home? Dump it into curry, turn it into fries and make a Chinese sweet dessert soup with it.
Since I don't really do deep-frying these days, I chose to bake it. Baking it also easier as I don't have to fry them in batches, less time consuming, less messy (no oil spattering every way) and also easy clean up. It might not be as crispy as the deep-fried one, but suit our family just fine.
1 large sweet potato, cut into French Fries shape
Season it with,
Sea salt to taste
After that coat it with rice flour.
Preheat oven to 400'F. Line a large baking sheet with foil and arrange the sweet potato fries in one single layer. Bake for 15 minutes. Turn it over and continue to bake for additional 20 minutes. Serve warm.
