We had this Japanese staple at Tanuki in Auckland the other day. I can’t think of a better preparation of eggplant on its own.
2 medium aubergine
120 ml dashi
2 tbsp dark soy sauce
2 tbsp mirin
2 tsp caster sugar
1 spring onion finely chopped
2 tsp grated ginger
If using medium aubergine slice them across into 25mm slices and score one flesh side in a pie pattern to half the depth of the slice. If using Japanese (small) augergine cut into two pieces and, slice in half lengthwise and score the skin in a 10mm grid. These cuts help the augergine to cook fully. Salt and leave for 30 minutes, wipe dry.
Add the dashi, soy, mirin and sugar to a small saucepan and bring it to a boil. Turn off the heat and put aside.
Heat oil in a frying pan or a shallow saucepan to 180C. The depth of oil should be at least half the thickness of augergine. The deeper the oil, the faster it will cook. Fry augergine pieces 2 minutes scored side down, then turn over and cook for 1 minute until the augergine is browned and very soft inside. Drain on paper towels. Pour sauce over, sprinkle with spring onion and ginger and serve.
If you feel that the augergine skin is a bit tough (this can happen when fried too long or the augergine is very large), soak the augergine in the dashi sauce, scored side down, before serving, for 30 minutes or more. Serves 4.
