赤えんどう豆 aka endo mame. Red peas, from Hokkaido.
I’ve found these in a depachika. It’s the under-ground flour of a department store where there are many specialty shops of food, ready to eat, fresh and ingredients. I had never used these peas.
After soaking a few hours.
And boiling 45 minutes. I could then use them for 3 dishes.
Japanese style : reheated on low heat, 15 minutes, with enough broth to cover, a piece of kombu seaweed, soy sauce and kurozato black sugar. Let cool. They can be kept about a week in the fridge and served as side dish for Japanese meals.
