Gomadashi / fish sesame paste

I first encountered the expression gomadashi on a website introducing regional udon specialties. It is a paste made of grilled fish, sesame seeds, soy sauce and sweetener. The paste's name does not intuitively convey how tasty it is. It is typically served with udon wheat noodles. It is also good with rice and as an addition to a number of dips and dressings. When making the paste, grilling the fish takes the longest, and once it is done, the paste should keep in the fridge for a relatively long time -- 4 weeks when made with regular soy sauce is what people say, so probably 2+ weeks with the reduced sodium version below.

Somen no tonyu tsuketsuyu / soy milk dipping sauce for thin wheat noodles

This mild and rich soy milk-based dipping sauce is quite filling. Pair it with somen or hiyamugi noodles or thin udon noodles accompanied by goodies for a more substantial meal. Among condiments, ginger goes especially well with this dipping sauce, so grate more than usual.
