Ingredients
Directions
Prepare
Slice the onions, turnips, and carrots thinly, and chop the celery into small pieces.
Make the stock
Heat the butter in a stewpan, add the vegetables, and sauté gently for 30 minutes with the lid on.
Shred the lettuce and add it along with the sliced tomatoes, herbs, spices, and water to the stewpan.
Bring the mixture to a gentle boil, skimming off any scum that rises.
Cover and simmer gently for 1.5 hours, then strain the stock.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that carries flavour from the vegetables and helps them soften gently without browning.
- Onions
- Provide sweetness and savoury depth as they soften and release their sugars.
- Carrots
- Add natural sweetness and body to the stock as they cook down.
- Lettuce
- Adds a mild, fresh vegetable flavour and a little extra body to the liquid.
The step that matters
Bring the mixture to a gentle boil and skim. Scum is coagulated protein and impurities that rise to the surface; skimming them keeps the stock clear and clean-tasting. Boiling hard would emulsify fats and cloud the liquid, so keep the boil gentle.
Swap the onion
