For the spring salad
12 Jersey Royal potatoes
10 green asparagus spears, sliced on an angle
150g/5½oz young broad beans, podded
150g/5½oz peas, podded
150g/5½oz fresh or frozen soy beans
3 spring onions, sliced on an angle
drizzle of olive oil
4 purple asparagus spears, sliced using a peeler
1 lemon, juice only
2 shallots, cut into rings
15 mint leaves, 10 torn, 5 shredded
small bunch of chervil
punnet of pea shoots
sea salt and freshly ground black pepper
For the dressing
1 tbsp Dijon mustard
5 tbsp red wine vinegar
1 tsp walnut oil
300ml/10½oz extra virgin olive oil
Bring a large pot of water to the boil and blanch the potatoes, drain and carefully slice in half.
Bring a large pot of salted water to the boil. Drop in the green asparagus, broad beans, peas, soy beans and spring onions and cook for a couple of minutes. Drain and run under cold water to stop them cooking but not to cool them.
Spread on a tray with the potatoes. Sprinkle with a little olive oil and season with salt and pepper.
Put the purple asparagus in a bowl and sprinkle with lemon juice and salt to cure and soften.
For the dressing, whisk together the mustard and vinegar in a bowl, slowly adding the oils. It should have a thick consistency, like a sauce. Season with a good amount of salt and black pepper.
Mix all of the vegetables with the shallots, mint, chervil, watercress and pea shoots and pour over the dressing.
Divide between four plates and dig in.
