Paul Foster uses beef striploin to create this striking dish of tender pink meat, cooked medium-rare, and a vibrant green purée of alexanders and parsley. It's worth the time spent foraging for the alexanders as they add a fragrant, aromatic quality to the recipe, but if you cannot find them, you can use all parsley for the purée instead, and substitute the caramelised shoots for your choice of green vegetable. Remember to remove the beef from the fridge an hour before serving to allow it to come up to room temperature.

Method
1
Start with the braised kombu. Place the dried seaweed in a small pan and leave to soak for 1 hour, or until soft and pliable
- 100g of kombu seaweed , dried
- 400ml of water
2
Once the kombu has finished soaking, place the pan on a very low heat and cover with cling film. Cook gently for 2–3 hours with the seaweed completely covered – topping up the water if necessary – ensuring the liquid doesn't come up to the boil. Reserve in the pan of liquid until ready to serve
3
Meanwhile, prepare the pickled onions by placing the vinegar, wine and sugar in a pan and bringing the mixture to the boil. Add the red onion quarters and immediately remove the pan from the heat. Cover with cling film and leave to cool until ready to serve
- 100ml of white wine vinegar
- 75ml of white wine
- 50g of sugar
- 1 red onion, peeled and quartered
4
For the alexander purée, bring a pan of water to the boil over a medium heat and add the potato slices. Cook for 5–10 minutes until just cooked through
- 100g of potatoes , peeled and sliced
5
While the potatoes are cooking, add a drizzle of sunflower oil to a pan and place over a medium heat. Add the sliced shallots and a pinch of salt and sweat down for a few minutes until softened
- sunflower oil, for frying
- 2 banana shallots , sliced
- 1 pinch of salt
6
Add the stock to the pan and bring to the boil. Stir in the alexander leaves and parsley and cook for 30 seconds, then remove from the heat and transfer to a blender along with the potato slices. Blitz together to form a smooth, loose purée, adjusting the seasoning if required
- 400ml of chicken stock
- 200g of alexanders, leaves only
- 100g of flat-leaf parsley
7
Pass the purée through a fine sieve to ensure it is completely smooth, transferring to a clean pan. Place over a very low heat and keep warm until ready to serve
8
Preheat the oven to 140°C/gas mark 1
9
Place the trimmed fat from the beef in a ovenproof frying pan over a low heat. Heat until the fat begins to render down and coat the pan, removing any remaining solid pieces. Increase the heat of the pan and sear the beef on all sides until dark and golden-brown then transfer to the oven. Cook for 10–15 minutes until medium-rare, with a core temperature of 50°C

10
Remove the sheets of braised kombu from their cooking water and cut into small squares. Return to the pan and warm through gently over a low heat. Meanwhile, drain the red onion from their pickling liquor and cut into thin slices
11
Once the beef has cooked, remove from the pan and set aside to rest for 5 minutes. Place the roasting pan back on the heat and add the alexander shoots to fry in the residual fat for a few minutes until caramelised and golden
- 8 alexanders, shoots only, cut in half lengthways
12
To serve, carve the rested beef into 1cm slices and arrange on warmed serving plates with a spoonful of purée, the caramelised shoots and slices of red onion. Drain the squares of kombu and scatter over the plate before garnishing with the carrot and parsnip slices
