Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Cressey Soup
Ingredients
Directions
Prepare
Scrape the carrots clean and slice the red part thinly.
Make the soup base
Put the carrots, water, turnips, celery, leeks, onions, and split peas into a stew pan.
Stew all together until tender, adding stock to prevent burning.
Rub the mixture through a tamis.
Finish and serve
Add 5 pints of veal stock and blanched watercress to the pulp.
Bring to a boil for 20 minutes, skim, season with salt, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red carrots
- Provide the main body, sweetness and colour of the soup once puréed.
- Split peas
- Thicken the soup and give it body as they break down during stewing.
- Veal stock
- Supplies the savoury meaty base and liquid for the finished soup.
- Leeks
- Add mild onion-like aroma and savoury depth to the base.
- Onions
- Add aroma and savoury depth as they soften and sweeten during stewing.
The step that matters
Stewing until tender while adding stock. Stewing slowly with added stock keeps the vegetables and peas from scorching on the pan base. Scorched flavour carries through into the purée, and the vegetables must be fully soft so that rubbing them through a tamis yields a smooth, even soup.
