You don't need an oven to make this.It's a super easy cold Japanese dessert.Use your choice of anko bean paste, tsubu-an or koshi-an.These go great with tea during the hot summer months.
I just love mizu-yokan.
-With koshi-an (smooth sweet bean paste), these turn out nice and silky. The texture is delightful.-They turn out more delicious with a sweet an paste.
Enjoy Japanese food around the world.
