Much as we love a salad the humble lettuce leaf occasionally deserves a change and this easy soup, as delicious hot as it is cold is a great way to use salad leaves and cucumber. A refreshingly iced soup can be very welcome on a hot day and has the advantage of being easily freezable if you don’t want to use it straight away, something that cannot be said of the average salad so a very useful recipe to have if faced with rows of bolting lettuce leaves and in our case, enthusiastic cucumbers.
If you happen to have some nasturtiums growing or see some at a farmers market, pop some of the leaves into the soup and use a flower as a pretty garnish. They are lovely, fantastically easy to grow; the leaves offering a wonderful peppery flavour, while the flowers add a certain style to your salad bowl or as here make a pretty garnish.
I love this with some of that wonderfully mild French goats cheese whipped up with lemon and chives. You can use it as a garnish for the soup or serve separately on toasted sourdough. Either way, it works so well with the delicate soup and makes it a bit more substantial.
This recipe serve four but add and subtract according to what you have available – fennel leaves, courgette, spinach, peas etc will all work well. Mint is surely the ubiquitous summer herb and I use it in everything I possible can during the warmer months. There are so many interesting varieties available to us now – ginger mint is a current favourite that makes a gorgeous restorative tea and I have just planted basil mint which I think is going to be a very promising addition to the kitchen garden.
Spinach is not essential but certainly helps with the colour.
2 medium shallots, finely chopped
1 stick celery (not essential!), finely chopped
1 clove garlic, finely chopped or grated
1 generous tablespoon olive or rapeseed oil
750ml vegetable stock (I use the non vegan marigold, green pot)
2 or 3 new potatoes, peeled and chopped
1 whole cucumber, chopped with skin
Big double handful of mixed green lettuce/spinach leaves
Handful of nasturtium leaves (optional)
Big handful of chopped garden mint
Four heaped tablespoons natural yoghurt (always green Yeo valley for me!)
Sea salt and black pepper
Lemon, rind and juice
1 tub French goats cheese
Handful of chopped chives
Four nasturtium flowers
Extra virgin olive oil
Heat the oil in a saucepan and add the shallot, garlic and celery if using. Sauté gently until softened but not brown. Add the potato and straight away 600ml of the stock. Bring up to a simmer and cook unail the potatoes are soft.
Add the cucumber, simmer for two or so minutes and then add the lettuce, spinach, herbs etc. Season well.
Allow to cool a bit and then whizz with a stick blender or in a liquidiser. Add more stock until the co sister is of a thin cream. When most of the heat has gone whisk in the yogurt and lemon juice to taste. Blitz again and if you feel it needs more yoghurt you could add that now.
Put the soup into a fridge to chill for a few hours.
When ready to serve, put the goats cheese into a,bowl and add the rind of the lemon and chopped chives. Whip together with a small whisk until smooth. Season.
Serve the soup in chilled bowls with a quenelle of goats cheese in the centre, garnish with a nasturtium flower and drizzle over some extra virgin olive oil.
