I love the spinach Goma-ae at my local Japanese restaurant and have just started trying to replicate their sesame dressing at home. This recipe isn’t exactly the same, but it’s still good. When I make Gomae-ae at home, I prefer to use steamed broccoli.
My tweaks: I use sesame paste or plain tahini instead of grinding the sesame seeds myself. I add some roasted sesame seeds (whole) for texture.
