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 ↓
Vegetable Porridge
Ingredients
Directions
Prepare the vegetables
Scrape and peel six carrots, six turnips, six onions, three heads of celery, and three parsnips.
Slice all these vegetables very thinly.
Simmer
Put the sliced vegetables into a two-gallon pot with four ounces of butter, a handful of parsley, a handful of chervil, and a good sprig of thyme.
Fill the pot with water or pot liquor, if available.
Season with pepper and salt.
Bring the mixture to a gentle boil on the fire for two hours.
After two hours, the vegetables will be done to a pulp.
Strain and serve
Rub the mixture through a colander with a wooden spoon.
Return the mixture to the pot and stir over the fire to heat it for dinner.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Sweetness and body as they soften and break down into the broth.
- Turnips
- Adds mild earthy flavour and bulk as they cook down to a pulp.
- Onions
- Build savoury depth and sweetness during the long, gentle simmer.
- Celery
- Contributes aromatic flavour and body once cooked down.
- Parsnips
- Add natural sweetness and thickening body when cooked to a pulp.
- Butter
- Adds richness and a silky mouthfeel to the finished porridge.
The step that matters
Holding a gentle boil for two hours. A gentle simmer lets the vegetables soften fully so they break down into a pulp, while a hard boil or too little liquid can scorch the bottom of the pot and leave the mixture uneven.
