Why it works: Parsnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 165 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Vegetable Puree
Ingredients
Directions
Prepare
Chop a large plateful of assorted vegetables, ensuring to include potatoes or beans for thickening.
Make the base
In a saucepan, heat ½ cup of dripping or stock-fat until very hot.
Add sliced onions and stir well to prevent burning.
Once the onions are red, stir in 1 large spoonful of flour until it reaches the same color.
Gradually stir in 1 pint of hot water along with salt and pepper, avoiding adding them too early to prevent burning.
Add the remaining vegetables.
Let them simmer for two hours, adding more hot water as needed.
Finish and serve
Press the mixture through a colander.
Return it to the heat.
Simmer until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down when cooked to thicken the puree and give it body.
- Beans
- Break down when cooked to thicken the puree and add body.
- Flour
- Cooked in the fat to form a roux that thickens the liquid.
- Onions
- Soften and sweeten as they cook, adding savory depth to the base.
- Dripping or stock-fat
- Carries heat and flavor into the vegetables and helps the flour cook.
The step that matters
Stirring the onions and flour. Onions can scorch in very hot fat, and flour that is not stirred constantly can clump or burn before the roux develops. Keep the heat controlled and stir steadily.
