Chilled Lemon Grass and Coriander Vichyssoise

 

This is an absolutely delightful chilled soup: perfect for a starter at a summer lunch or supper party when the weather is hot. It’s light and refreshing, fragrant and elegant; and the combination of the coriander with lemon grass produce a really lovely but delicate Thai flavour. There’s no coconut milk in it, which I was surprised about, but the inclusion of new potatoes provide the necessary substance without the cloyiness that you sometimes experience with coconut milk. Really delicious – give it a go!

Serves 4

What you need…

2 handfuls fresh coriander

4 lemon grass stems

4 spring onions

50g butter

2 medium onions, chopped

275g new potatoes, chunked

150ml milk

Sea salt and black pepper

What to do…

First of all, you need to make a stock. In a large saucepan, pour 850ml water. Pick the leaves from the coriander and chuck the stalks into the water, saving the leaves for later. Likewise, with the spring onions and lemon grass: trim the ends, remove the outer skin, chucking those bits that you would normally discard into the water as well. Pop a lid on the pan, and bring the water to boil before reducing the heat to gently simmer the ‘stock’ for 30 minutes – it is this process that provides the soup with real depth of flavour.

Meanwhile, chop up your lemon grass and spring onions.

Strain the stock into a jug, discarding the trimmings. Wipe out your saucepan and then add the butter, melting it over a low heat. Add the lemon grass, onions and potatoes, pop the lid back on the pan and gently ‘sweat’ the vegetables over a low heat for 10 minutes. Then, add the stock, milk and three quarters of the coriander leaves (retaining the rest for the garnish). Season with sea salt and black pepper, pop the lid back on, turn the heat up so that the soup just starts to boil and then reduce the heat again and let the soup simmer gently for 25 minutes.

Leave the soup to cool and then chuck the lot into your food processor/blender and whizz until smooth. If you want a really smooth, silky soup, strain it through a sieve into a jug. If not, just tip it from the processor into the jug. Cover with cling film and keep in the fridge until you’re ready to enjoy this lovely soup.

Pour into bowls and sprinkle over the remaining coriander leaves and chopped spring onions: delightfully delicious!

How easy…

An absolute sinch – takes some time but you can walk away to do other things whilst it’s gathering its flavours. Also, you can make it the day before and keep it in the fridge until you’re ready to garnish and serve: no hassle!
