Ebi mayo (エビマヨ) is a Japanese-Chinese (chuka) restaurant classic and a favourite in Japanese convenience-store bento and on izakaya menus. Prawns are coated in a light, crisp batter and tossed in a sauce of Kewpie mayonnaise, condensed milk, ketchup and a little lemon.
It's a cousin of the honey walnut prawns you see at Chinese restaurants, but tangier and less sweet. Kewpie mayo is what makes it, so it's worth having a bottle in the fridge.
Toss the prawns in the sauce right at the end so they stay crunchy.
