What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a ricer or food mill for the smoothest, lump-free texture if you prefer; otherwise a hand masher works well.
- 2Warm the milk gently on the stovetop or in the microwave before adding to keep the mash hot and creamy.
- 3Avoid over-mashing or using a food processor, which can release excess starch and make potatoes gluey.
- 4Steam-dry the drained potatoes in the hot pot for a minute — this removes residual moisture for fluffier mash.
- 5Add wasabi paste gradually and taste as you go; the heat blooms slightly after sitting for a minute.
- 6Make ahead: prepare the mash without wasabi, then reheat gently and stir in the wasabi just before serving.
