Place the soy sauce, lemon juice and vinegar into a jug and whisk to combine

Add the coriander and set aside

Place 300mls of the olive oil into a large frying pan and heat over a low temperature to 60°Celsius

While waiting for the oil to come up to temperature, heat the rest of the olive oil in a separate frying pan over a medium temperature

Add the mushrooms, season and cook until soft

Place the mushrooms into the dressing

Add the trout to the warmed up oil and poach for 6 minutes

Remove from the oil and place on top of a salad greens, potato salad, or chopped tomatoes (as I have done here)

Add 100mls of the poaching oil to the mushroom dressing

Top the fish with the mushrooms and serve straight away
