How to prepare other ingredients
Yam cake - cutting into bite-size pieces
Using a spoon to cut will result in a surface that is coarser than one cut using a knife, so flavor will be absorbed easier. You can also use your fingers to tear into bite-size chunks.
Yam cake - rubbing with salt
Rub yam cake with salt to remove its distinct odor. Use about 1 Tbsp of salt for 1 large yam cake. Rinse quickly and wipe dry before using.
Yam cake - parboiling
If you quickly place the yam cake into boiling water (parboil) the distinct odor of the yam cake will be removed, flavor and seasonings will be soaked up easier, and the rubbery texture will be refreshed. The appropriate boiling time is for 2 to 3 minutes in water that is at a rolling boil. Avoid over-boiling as this will result in hard yam cake.
