We call any vegetable dish dressed with sesame Goma-ae (goma is sesame in japanese, ae is dressed with in Japanese). It could be with white or black sesame, but please use roasted sesame (Iri-goma). If you don’t have any, roast seeds in a pan for a few minutes with a touch of water until it starts to have nice roasted smell. (You don’t need any oil for roasting!). Then grind it. This increases the flavour and the lovely roasted aroma. Grunding semame is also easier to digeste, and you can get more nutrition out of the sesame.
This sesame sauce works for spinach, carrots and more many vegetables. Black or white sesame? It’s up to you! Also you can use brown sugar instead of white.
This dish is good for Bento too. It’s normally served at room temperature.
