For this dish, I like to use Kewpie mayo, a Japanese mayo, instead of traditional American mayo. It’s made with egg yolks only, not whole eggs, and has a sweeter flavor and a lighter texture than its American counterpart. Never leave a child unattended in the kitchen. This recipe is appropriate for children of various ages. When a recipe calls for cooking on the stove or using a knife, an adult should do those activities and let the child assist, if age appropriate.
