In a small mixing bowl, whisk the tomato paste with 1⁄2 cup (120 ml) water and set aside.

Distribute the remaining reheated rice over the top, and use a damp spatula to press the rice down so it makes a layer that seals the fillings in. Toast the cake in the pan for about 10 minutes.

A large plate of the Cantonese-style sweet pan fried cakes dipped in egg is $8.95, while a stir-fried platter of the savory cake slices starts at $11.95, depending on the meat or seafood.
