- In a saucepan, place peeled potatoes and enough water to cover the potatoes and boil until they become soft.
- Drain the potatoes and spread dashi well over them. Then, mash the potatoes roughly with a fork. Put them back to cook on the stove for about 2 mins and add rice or sushi vinegar. Remove potatoes from the heat and put in the fridge to cool off.
- Mix in the rest of your ingredients. Then combine salt, Japanese mayonnaise and spicy shichimi togarashi (optional). Garnish with sesame seeds and serve.
