Fish with Lime & Miso Butter

Fish with Lime & Miso Butter

Ever since I realised that you don’t need to make them in advance, I’ve been getting more and more into flavoured butters.


I mean it’s butter with extra flavours. And it only takes a few minutes to make the most amazing sauce.


What’s not to love about that?


The only trick here is you need to have your butter at room temperature before starting. However, you can always give it a zap in the microwave if you forget. Apart from the middle of Summer I keep some butter in the pantry so it’s always ready to go.


I’ve used shiro or white miso here. It has the mildest flavour of the miso pastes. If using a darker miso, start with less and add to taste.


And if you don’t have any miso you should get some (see here for other miso ideas) or see the variations below for a miso-free option.

Cook Time 15 minutes
Servings 2 people

Ingredients

  • 80 g (3oz) unsalted butter
  • 2 tablespoons miso paste
  • 2 teaspoons lime juice + lime halves to serve
  • 2 tuna steaks or other fish
  • 1 bag baby spinach or salad leaves

Instructions

  1. Place butter in a small bowl with the miso and lime juice. Smash with a fork to mix thoroughly. Taste and season with more miso if needed (but you probably won’t!).
  2. Heat a frying pan or BBQ on a medium high heat. Rub fish with oil and sprinkle with a little salt, remembering the miso butter is pretty salty. Sear fish for 3-5 minutes on each side or until cooked to your liking.
  3. Divide spinach / salad between two plates. Top with fish and smear the butter over your fish so that it melts to form an incredible sauce.
