Banh tom (Sweet Potato Shrimp Cake) is another Vietnamese dish originating from Hanoi and is made of deep-fried and battered sweet potato and shrimp. The orange color is from the natural flesh of sweet potato and a little bit of turmeric powder in the batter. Often served as an appetizer, banh tom is commonly wrapped with lettuce, herbs and pickled vegetables, and then dipped in a special sauce. The sweetness from the potato is balanced by the oil. It goes great with beer, and the fritters stay nice and crispy for hours
