Egg Custard Chawanmushi

We made this and it was good. https://www.justonecookbook.com/instant-pot-chawanmushi/

Used black tree oyster mushrooms and shiitakes diced.

Topped with sliced scallions and a tbsp of soy sauce.

We rested it for 25 minutes without opening and it was perfectly set in a 4" tall bowl 6" diameter.

Last time we waited like 15-20 minutes, and we opened it half way, and it was not set…
