Story Behind this Recipe
My husband criticized my hamburgers as too hard. I was a bit frustrated by this, so I decided to aim for the ultimate softness . It would be great if your husband gets excited like mine does now when he sees the hamburgers in his bento .
Shown in the photo is double portions for my bento stock . The sauce tastes really delicious on top of omurice.
It cooks through when stewing, so brown the patties on both sides in the oven to cook the burgers, and it'll result in soft burgers . They are really fluffy.
