Why it works: Turnip and parsnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 590 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Prepare
Clean and cut the carrots, celery, turnips, onions, lettuce, parsnips, and herbs.
Make the stock
In a stewpan, combine the vegetables with fresh butter and a little water.
Stew until the water evaporates and the butter begins to hiss.
Fill the pan with fresh water, then add nutmeg, pepper, salt, and green peas.
Simmer for three hours.
Strain the stock and store in a stone crock in a cool place until needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness and body to the stock as they simmer.
- Onions
- Add savoury depth and aroma as they soften and release sugars.
- Celery
- Contributes aromatic flavour that rounds out the stock.
- Butter
- Carries flavour from the vegetables and adds richness when stewed first.
The step that matters
Stew until the water evaporates and the butter begins to hiss. Cooking the vegetables in butter until the water is gone lets them brown slightly and concentrate flavour. Adding water too early would simply boil them, producing a flatter stock.
