Preheat your oven to 200°C. Put a large saucepan of water with a pinch of salt on to boil for the potato. Chop the potato (no need to peel!) into 2cm chunks and add to the saucepan. Simmer, 15-20 mins. TIP: The potato is done when you can easily slip a knife through. Pick the tarragon leaves and roughly chop (discard the stalks). Peel and grate the garlic (or use a garlic press). Remove the roots from the spring onion and thinly slice.

Lay a chicken breast on a chopping board, place your hand flat on top and slice into it from the side (be careful not to cut all the way through). Open it up like a book. You've now butterflied your chicken! Repeat for all chicken breasts. IMPORTANT: Remember to wash your hands and equipment after handling raw meat.

Heat a splash of oil in a frying pan over high heat. Season the chicken with salt and pepper. Once the oil is hot, lay it in your pan and brown for 2 mins on each side. Transfer to a lined baking tray, sprinkle over half the tarragon (add less tarragon if you're not keen). Don't wash your pan yet. Roast the chicken on the top shelf of your oven, 12-14 mins. IMPORTANT: The chicken is cooked when it is no longer pink in the middle.

When the potato is cooked, drain in a colander and leave the steam to evaporate for a couple of minutes, then tip back into the pan. Mix in the spring onion and the butter. Crush the potato gently with a potato masher or fork (don't mash completely), then season to taste with salt and pepper. Keep warm with the lid on.

Once the chicken is done, transfer to a clean chopping board covered in foil. Heat the frying pan you used earlier over high heat and add a splash of oil if it is dry. Add the sugar snap peas and stir-fry for 2 mins before adding the garlic. Add a splash of water, cover with a lid and steam-fry for 2 mins. Season with salt and pepper, then pop onto your plates.

Lower the heat to medium and add the redcurrant jelly and water (see ingredients for amount) to the now empty frying pan. Stir to melt the jelly. Let it simmer gently and reduce, it should look nice and glossy. Stir through the remaining tarragon. Serve the potato alongside the sugar snaps and place a chicken breast on top. Finish by drizzling over the redcurrant sauce. Enjoy!
