Tungku Batu Sungai

Methods to prepare:

1. Heat the river stone for about 5-20 minutes. Use a gas stove to cook over low heat. Do not use a high heat because the stone will crack and split.
2. Not too long if you don’t want the fabric to burn. Cover the cloth with betel leaves, noni or galangal leaves before placing the stone.
3.  Do it in each section for 5-10 minutes and repeat in the other section.
4.  Normally, the heat of the stone can last about 1 hour.
