Green lentils hold their shape where red ones collapse, so this comes out as distinct glossy lentils in a dark savoury juice rather than a puree. It is a side dish that quietly works as a main.
No salt goes in at the start, and not for the usual disputed reason about skins. It is that the yeast extract is already extremely salty and you cannot take it out again.
- Oil in the pan, dried onion in, and let it sizzle gently for a minute until it smells sweet rather than dusty. It will colour quickly, so keep it moving.
- Lentils in, stirred through the oil, then about 700 ml of water and the herbs. Bring up and simmer, lid ajar, for 25 to 30 minutes.
- The yeast extract goes in at 20 minutes, not at the start. Dissolve it in a little of the hot liquid first. Added early it catches on the base and turns bitter; added late it stays clean and savoury.
- When the lentils are tender and there is just a glossy amount of liquid left, take it off and stir in the vinegar.
The vinegar is not optional. Without it the dish is heavy and one-note, and the whole thing lifts the moment acid arrives. Pepper at the end.
Good under a fried egg if you have one, on toast if you have bread, and best of all with the flatbread on this site.
