This year, the big hit at home was Hiyashi Chuka with Soupy Sesame Sauce.
To make the sauce for 2 servings, I simply whisk together 1T sesame paste, 3T soy sauce, 1.5T raw brown sugar, 2tsps black vinegar, 1T sake (once boiled), 1C Chinese-style chicken stock, 1T lime juice, 1tsp la-yu (hot chili oil), and 1tsp sesame oil.
Then, enjoy the noodles and sauce with whatever the toppings I feel like for the day...such as shio-koji marinated steamed chicken tender, boiled egg, daikon, radish, seaweed, scallion, cilantro, etc.
I especially like it with extra homemade chuncky la-yu on top.
