Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Chestnut Pie
Ingredients
Directions
Prepare the filling
Boil the chestnuts until partly tender, then remove the skins.
Cut the celery into pieces, discarding the very hard outer pieces.
Slice the onion and stew it in 1 pint of water until tender.
Mix the chestnuts, celery, onion, and 1 oz of butter.
Season the mixture with pepper and salt.
Assemble and bake
Make pastry using the wheatmeal, 3 oz of butter, and a little cold water.
Turn the vegetable mixture into a pie dish.
Cover with pastry.
Bake for 1 hour.
Serve with brown gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the main bulk and starchy, floury texture of the filling.
- Butter
- Adds richness and fat, carrying flavour and softening the filling.
- Allinson fine wheatmeal
- Forms the flour base of the pastry, giving it structure once baked.
- Spanish onion
- Adds savoury sweetness and aroma as it softens in water.
The step that matters
Cover with pastry. The pastry must seal the filling fully so steam and juices are held in while baking, and the pie does not dry out or leak.
Swap the chestnut
How well each one fits the dish's main ingredients (celery, onion, butter, pepper):
- Black-eyed peafits better
- Beansfits better
- Sesamefits about as well
- Chestnutthe original
Fit is the average pairing score against celery, onion, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
