Why it works: Flour and lemon are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 30,404 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Celeriac, Preserved
Ingredients
Directions
Prepare the celeriac
Peel and wash the celeriac roots, then cut the roots into quarters.
Trim the pieces to the same size.
Parboil them for 5 minutes.
Par-cook in the flour bath
Bring 2 gallons of water to a boil.
Mix 3 tablespoons of flour with a little cold water, then add the mixture to the boiling water along with the lemon juice and salt.
Add the celeriac roots and cook until three-quarters done.
Remove from heat and let cool.
Dip the celeriac roots in lukewarm water.
Can and process
Arrange them in quart tin cans.
Cover the roots with lightly salted cold-boiled water.
Seal the cans.
Boil them in a hot water bath for 1.5 hours.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Celeriac roots
- Form the main body of the preserve and keep their firm, tender texture after cooking.
- Flour
- Thickens the cooking liquid so it clings lightly to the roots.
- Lemon juice
- Adds acidity that brightens flavour and helps keep the roots pale.
The step that matters
Cooking until three-quarters done. Stopping at the right point leaves the roots firm enough to survive canning and the long hot water bath. Cooking them fully now would leave them soft and mushy once processed.
