A refreshing and vibrant dish that features tender potatoes, dressed with a flavourful combination of soy sauce, sesame oil, and various seasonings, resulting in a crunchy and savoury side dish with a hint of sweetness and tanginess.
Boil the potatoes until cooked but still firm. Grate the potatoes.
Mix the ingredients for the sauce (mayonnaise, sugar, soy sauce, sesame oil, hot mustard powder, salt)
together, using more or less sesame oil and hot mustard according to taste.
Put all solid ingredients together in a large bowl, then add the sauce and mix well. Chill.
