The rich, marbled texture of wagyu beef cries out for lighter, fresher flavours to accompany it. Where a recipe for creamy or buttery Western sauce might weigh down or overwhelm a good piece of wagyu, the tang of wasabi and the light umami of this Japanese tosa joyu (soy dipping sauce) are a perfect match. This recipe is meant to serve four people as part of a shared meal.

Cook's notes

Oven temperatures are for conventional; if using fan-forced (convection), reduce the temperature by 20˚C. | We use Australian tablespoons and cups: 1 teaspoon equals 5 ml; 1 tablespoon equals 20 ml; 1 cup equals 250 ml. | All herbs are fresh (unless specified) and cups are lightly packed. | All vegetables are medium size and peeled, unless specified. | All eggs are 55-60 g, unless specified.

Instructions

Standing time 2 days

You will need to begin this recipe 2 days ahead.

To make the tosa joyu, heat the sake and mirin in a saucepan and boil for 1 minute. Remove from the heat and immediately add the soy sauce, kombu and bonito flakes. Stand overnight, then strain through fine cheesecloth. Transfer the sauce to a sterilised glass bottle and stand for another night. (The sauce will mellow, mature and improve in flavour for months after bottling.)

Finely grate the daikon and transfer to a bowl. Stand for 10 minutes.

Meanwhile, season the steak well with salt. Heat a heavy-based frying pan until smoking hot. Rub the pan with a little wagyu fat. Cook the steak on both sides until medium-rare. Rest for 5 minutes in a warm, draft-free place. Slice the steak and transfer to a warmed plate.

Slice the lemon. Grate the wasabi and place a pile on top of the lemon slice. Lightly squeeze excess moisture from the daikon and place the grated daikon on the lemon next to the wasabi. Serve with the tosa joyu for dipping.
