Warm Puy Lentil Salad with Roasted Beetroot and Mustard

October. The light has changed. The kitchen window catches the last of the afternoon sun, lower now, warmer in colour if not in temperature. The beetroot I brought home from Saturday's market still had their leaves on, soil clinging to the roots, and they sat on the counter like something dug up from a painting.

This is the salad I make when summer has properly gone and I don't miss it. Puy lentils, the small slate-green French ones that hold their shape and taste of the earth they grew in. Beetroot, roasted until the edges caramelize and the flesh turns from raw and chalky to something dense, sweet, almost jammy. A dressing with enough mustard to make your eyes water, enough vinegar to cut through the sweetness, enough oil to bring it all together. Watercress underneath, because watercress has an iron bite that stands up to everything else on the plate.

I've written this one in the notebook several times across different years. The notes are always short. "Lentils. Beetroot. Mustard. Wednesday. Cold outside, warm bowl." That's all it needed. A recipe is a conversation, not a contract. The beetroot might be golden one week, the lentils dressed while still warm another, a few walnuts scattered on top if the mood takes you. Your kitchen, your rules.

There are few better feelings than putting a warm plate of this in front of someone on a dark evening. It looks like you tried. You did, but not very hard. That's the secret of it.
