Wasabi gives a hot horseradish edge to mayonnaise which pairs well with a seared tuna steak. 

Horseradish is pungent, sulphurous and therefore goes well with flavours that can stand up to it – enter oily fish.  Have you you ever tried oven baking a salmon filler in a parcel with a dollop of horseradish sauce? It’s delicious. Tuna and horseradish make an excellent combination too, and since wasabi is a Japanese horseradish the same rules of compatibility apply.

This is a light dish, perfect for a light lunch or summer evening. It does require you to have some home-made mayonnaise on hand, but if you don’t then a batch can be knocked up with relative ease.  A slow drizzle of oil into a food processor and patience is the key to making super mayonnaise. You will have lots of mayo spare to drizzle on future salads. In this batch I avoided mustard in the base as wasabi will bring that edge.

Recipe type: Dinner
Serves: 2
Ingredients
Dressing
  • 3 tablespoons of mayonnaise
  • 1 tsp Wasabi powder mixed with ½ tsp of water into a paste
  • ¼ juice lime
  • tablespoon chopped coriander
  • ½ tsp tamari
  • tsp chopped chives
Salad
  • Handful rocket leaves, half a large cucumber, julienned, a few coriander leaves
  • A dressing made from olive oil / garlic infused olive oil, splash tamari, Himalayan salt, squeeze lemon juice.
  • tsp sesame seeds
Tuna
  • 2 tuna steaks
Instructions
  1. First make up the dressing, by combining all the above ingredients in a small bowl. Chill till ready to use.
  2. Next make up the salad component by mixing the leaves with the cucumber and tossing with the dressing. Finish with a sprinkle of sesame seeds.
  3. Finally cook the tuna in a little coconut oil/ghee on a hot griddle pan for approx 2 mins on each side (less if you prefer it rarer I did manage to over cook mine). Leave the tuna to rest for a minute or so, then slice in half on the diagonal.
  4. Pile the salad on a plate, with the tuna on top, and finish with a blob of the hot mayonnaise and a pretty leaf of coriander.
