Pea and Mint Soup With Roast Jersey Royals and Radish Slices

Serves: 4
Takes: 30 mins

Two of my favourite seasonal stars in one dish, peas and jersey royals, could this be love. I’ve elevated the traditional pea and mint soup combo by adding a good smattering of flavour with some tender roasties and fresh radish thins. This is not the thin bland pea soup you’re used to. I recommend using fresh garden peas in this recipes, but frozen peas will do just fine.

When To Eat

I recommend eating this dish from June to September. If you’re eating this dish in June/July try getting your hands on some delicious jersey royals, otherwise traditional new potatoes will do just fine.

  • Halve the new potatoes and place on a roasting tray. Cover with 2 tablespoons of the olive oil and a decent helping of salt. Then place in a 200˚c oven for 20 - 25 minutes until golden and crispy.
  • Whilst the potatoes are cooking, peel and dice the garlic and shallots. Heat the remaining olive oil in a deep pan over a medium heat. Fry the garlic and shallots for around 3 - 4 minutes until soft. Roughly chop the lettuce and add to the pan, fry for about a minute, before adding the peas, mint and stock. Cover the pan and simmer for about 10 minutes. Then blend the soup using a hand blender or food processor until smooth. Season to taste.
  • Thinly slice the radish. Serve the soup in individual bowls with a good handful of the potatoes and a sprinkling of the sliced radish.
