during my stay in Beijing, I get to know Cream Fried Cake (nǎi yóu zhá gāo). Now I'm looking for the recipe.
But I only found this info:
"Cream Fried Cakes are made of flour, egg, cream, white sugar and vanilla powder. The dough is made with boiling water, so cakes usually bulge into a ball shape after frying in the oil. They are scooped up when they turn golden in color and finally covered with white sugar. It is a nutritious snack."
