Pan-Fried Tilapia

Pat the tilapia dry with kitchen paper. Season the fish with a pinch of salt and pepper. Heat a splash of oil in a frying pan on medium-high heat. Once the pan is hot, add the fish. Fry for 4-5 mins. Then, carefully turn and cook for 2-3 mins more. IMPORTANT: The fish is cooked when the centre is opaque. Remove from the pan, set aside and cover with foil to keep warm. Keep the pan - we'll use it again!

While the fish cooks, pop the green beans in your second pan of boiling water. Cook for 4 mins, then drain in a colander and put to one side. Boil your kettle, then pour the boiling water (see ingredients for amount) into a measuring jug with the stock. Stir to dissolve, ready for the tarragon sauce.

Once the tilapia is out of your frying pan, add the stock to your pan on medium-high heat. Boil until it has reduced by one-third, 4-5 mins. Remove from the heat, then add the crème fraîche. Give it a good stir, then add the tarragon (don't use it all if you only want a subtle flavour). Season to taste with salt and pepperif needed.

When the potatoes are cooked, drain in the colander and allow to steam-dry for 1 minute (you want as much water to drain out as possible). Return them to the pan and lightly crush with the back of a fork. For a decadent finish, toss them in a knob of butter (if you have some) and a pinch of salt and pepper
