To Prep
Soak dried shiitake mushrooms and scallops (optional) in 2 cups of water overnight to rehydrate and draw flavours into the water. The juices will be used as part of the soup stock.
To Cook
In a small pot, bring roughly 4 cups of water to boil and drop in konnyaku, return to boil, then drain and set aside the konnyaku.
Prepare the dashi by heating 4 cups of water in a saucepan over medium heat. Just before the water boils, remove the kelp from the saucepan.
Increase the heat to high and bring to a boil. Keep cooking for another 5 mins.
Lower the heat and add bonito flakes into the saucepan. When the water boils, turn heat off. Set aside to cool for at least 5 mins and let the bonito flakes sink to the bottom.
Strain the liquid through a strainer lined with a paper towel or several layers of cheesecloth. Set aside.
In the meantime, remove shiitake mushrooms and scallop (optional) from the water. Lightly squeeze to drain water and slice the shiitake mushrooms.
In a pot, add dashi, shiitake mushroom water and scallop (optional), seasoning and heat over medium-high heat.
Add in all the ingredients and bring to boil. Then, lower the heat to a simmer and keep cooking for another 20 mins, or until the taro softens.
Turn off heat and scoop into individual serving bowls. Best enjoyed hot.
