Teppan-yaki restaurants are the ones like Benihana’s, Domo77, Japan 77, Ron of Japan, etc. The golden shrimp sauce is put atop the grilling shrimp, then the lid is put on and the sauce puffs up and cooks during the steaming process. (I suspect it is an egg-based type of mayonnaise product) I’d like to know if it can be purchased commercially, or if it’s merely concocted–and what a good recipe for it is. Thanks, and have a great day!
