Yuzu-kosho may still belong to your list of unfamiliar Japanese ingredients. Yuzu-kosho is a spicy and salty condiment with the fragrance of yuzu citron. To make yuzu-kosho, the rind of yuzu is pickled with green or red chile pepper along with salt for nearly one year. Both green and red product have similar flavor characteristics. (Excerpt from The Sushi Experience http://hirokoskitchen.com/shop/the-sushi-experience/).
Yuzu-kosho is powerful. Even a tiny amount in the food preparation or as a garnish gives you a lasting kick of spiciness in our mouth.
I began to make Succotash-like summer salad/salsa many years ago when the summer vegetables become bounty. I got the idea from a grilled fish dish served at one restaurant. Fish was served with refreshing corn and summer vegetable salsa. Inspired by Succotash recipes found on line I decided to make my own version. By the way, according to Wikipedia, during the Great Depression Succotash was a popular dish, because ingredients used in the preparations are inexpensive. Wonderful to learn the history of the dish. https://www.google.com/search?sourceid=navclient&aq=&oq=Scuttash+&ie=UTF-8&rlz=1T4SKPB_enUS342US343&q=scuttash+corn+and+bean&gs_l=hp..0.41.0.0.0.11255………..0.RbstWw0NeKY
