I think of it as stone soup.
During our summer holidays in Brittany, nettle soup is always top of the list of meals we look forward to making. Still, the intent usually lies dormant until a fateful evening when we are caught off-guard with no dinner plan. There are always nettles about: in the bits of garden that haven’t been mowed, in the field at the bottom of the drive where a solitary horse used to live. The horse is long gone, the field remains ‘le champ du cheval.’ Armed with wellies, gloves, scissors, and a basket, it won’t take longer than ten minutes to gather dinner.
According to the folk tale Stone Soup, with just a soup kettle, water, a stone as decoy, and some craft, a clever traveller fools one mean farmer (or, depending on the version of the story, the inhabitants of a whole village) into relinquishing vegetables, one at a time, little by little, in order to make that initial ‘stone soup’ — a stone in a pot of water — taste better and better.
In my fairy-tale summer, the nettles are the stone, the nothing. Like that stone, they’ll need a bit of a boost in terms of depth and unctuousness. An allium of some sort, a couple of potatoes, a zucchini — all of which weren’t donated by villagers but are the neglected, long-term squatters of the vegetable crates in the cellar.
And in reality, nettle soup is the very opposite of stone soup. It has, it is true, sprung from nothing. But unlike the stone — ultimately discarded — the nettles are the very essence and raison d’être of the meal.
Nettle soup
Since the main idea of the soup is its fortuity, the ingredients and quantities are just indications. But the nettles must remain the focus, they should not be overpowered by the other vegetables.
A big bag of young nettle leaves
Butter
1 or 2 small onions or shallots, finely chopped
A few garlic cloves
2 medium potatoes, peeled and cut into chunks
Some chicken stock if available
Depending on season and availability, a few of the following:
Leeks, zucchini (courgettes), carrots, fennel, etc (all of which need to be washed well or peeled and cut into slices)
Crème fraîche to serve
With a pair of gloves to avoid getting stung, pick fresh young nettle stems (in season in spring and summer) especially the most tender part close to the tip.
(Still protected by gloves) pick the leaves off the stems and wash thoroughly in a large bowl of cold water. Drain and set aside.
In a large soup pot, melt a few tablespoons of butter. Add the chopped onions (or shallots). Sweat for a few minutes until translucent but not yet turning in color. Add a couple of garlic cloves and cook for a minute longer.
If using leeks, add to the onions and garlic now. Cook for about 3 to 5 minutes.
Add the potatoes and any other vegetables and immediately cover well with water or/and chicken stock (there should be enough liquid to account for the nettle leaves later). Bring to a slow simmer and cook for about 15 minutes until the vegetables are tender.
Add the nettle leaves and cook for just a few minutes, until they are wilted and soft but still bright green! (Add a little boiling water or stock to cover the leaves if necessary.)
Remove from the heat and purée the soup until unctuous using a hand mixer or, in batches, in a food processor.
Finally, a game-changing tip from my peripatetic sister — inspired by the Egyptian soup molokhia: Just before serving, smash or finely chop a couple cloves of garlic and cook in a puddle of butter in a corner of a skillet. Remove just as it turns golden and stir into the soup immediately before serving.
Garnish with crème fraîche if desired.
