How to prepare other ingredients
Bamboo shoots - cutting off the tip
Diagonally cut off the tip.
Bamboo shoots - making a vertical slit
Make a vertical slit into the skin to allow for faster cooking. After boiling, start peeling the skin from this slit.
Bamboo shoots - parboiling
Using rice grains is an easier alternative to rice bran (nuka) for parboiling. Also add in a red chili pepper to reduce the amount of scum that will form on the surface of the boiled water.
