Your Oyster Recipe of the Day: Oyster Rice Bowl (Oyster Donburi 牡蛎丼). For this Japanese rice bowl, oysters, onions and ginger juice simmer in a sauce of dashi stock, soy sauce and mirin and then get topped with lightly beaten eggs. When the eggs are steamed, serve atop steamed rice. I’m loving the simple recipes like this one on Noob Cook.
