Do you know what else you can do with the donabe rice cooker? This is what I like doing often when I make rice with my double-lid donabe rice cooker, "Kamado-san".
I put the raw eggs on the inner lid of the donabe before covering with the top lid. Make sure the wholes are not blocked.
Then, I make the rice just like usual. (15 minutes over medium-high heat.) After turning off the heat, the rice will be rested for 20 minutes with the lids on. Meanwhile, about 10 minutes into the resting time, I just quickly open the top lid and remove the eggs.
The perfectly cooked boiled eggs are made without boiling! Somehow, they taste better than the regular boiled eggs.
Happy donabe life.
