Celery Seed Apium graveolens
Tiny, and far stronger than it looks. Half a teaspoon does what a whole head of celery would, which is the entire reason it exists.

In the kitchen
Half a teaspoon, not a tablespoon
Celery seed is one of the most concentrated things in a spice rack, and its bitterness compounds. Half a teaspoon seasons a large pot of coleslaw or a court bouillon; more turns the whole thing bitter.
It is a pickling and brining spice
Standard in pickling blends, in brines for pork and poultry, and in coleslaw dressing. Its job is to supply celery's savoury base note where actual celery would add water and bulk.
Crush it for a dressing
In a cold dressing the whole seed stays hard and releases little. Crush it in a mortar first, or let the dressing stand an hour before serving.
Beyond the kitchen
THE BLOODY MARY
Celery salt on the rim is close to obligatory in a Bloody Mary and is standard on a Chicago hot dog. Both are twentieth-century American conventions built on a very old European seasoning.
GREEK VICTORY WREATHS
Wild celery, not parsley, was used for the victory crowns at the Nemean Games, one of the four Panhellenic festivals. The plant carried funerary associations across the Greek world.
A DECLARED ALLERGEN
Celery in all forms, including the seed, is one of the allergens that must be declared on food labels in the European Union and the United Kingdom. It appears in a surprising number of stocks, blends and processed foods.
NITRATE IN CURED MEAT
Celery powder is naturally high in nitrate and is widely used to cure meats sold as uncured or nitrate-free. The chemistry is essentially the same as with added nitrite; only the labelling differs.
A longer history
Wild celery grows across Europe, North Africa and western Asia and was used for thousands of years before the stalk vegetable existed. Greek and Roman sources describe it, and its seeds and leaves appear in Egyptian tombs, including in garlands from Tutankhamun's burial.
The plant carried ritual weight in the Greek world, where it crowned victors at the Nemean Games and was strongly associated with funerals and the dead. Its culinary use across the ancient Mediterranean was as a strong herb and seasoning rather than as a vegetable.
Stalk celery was bred in Italy in the seventeenth century and became the familiar vegetable; the seed stayed as a separate seasoning and became particularly embedded in American cooking — in pickling, coleslaw, Old Bay, celery salt and the Bloody Mary. India is now the largest producer of the seed.
