Carrot and Coriander Soup

There's a bag of carrots in every kitchen in the country. They sit in the bottom of the fridge or in a paper sack on the counter, patient and undemanding, waiting for someone to do something decent with them. This soup is the best thing you can do.

I make it in October, when the first cold evenings arrive and the carrots at the market are fat and deeply orange, still flecked with soil. The ground coriander goes in early, toasted in the butter until it smells warm and almost like citrus. The fresh coriander goes in at the end, stirred through just before blending so the green, peppery brightness survives the heat. Between the two of them, they turn a bag of cheap carrots into something that tastes like you tried harder than you did.

There is a reason this is one of the most-made soups in Britain. It costs almost nothing. It takes less than an hour. It feeds four people from a few root vegetables and a bunch of herbs. And it's good. Quietly, reliably, without fuss. I wrote it down in the notebook years ago with a single line: "carrots, coriander, Wednesday, rain." That's the whole story.

A recipe is a conversation, not a contract. If your carrots are sweet, ease back on the cooking time. If they're woody and late-season, give them longer. Trust your nose. The soup will tell you when it's ready.
