The Root Cellar
I. The Ingredient
II. Origins & History
Horseradish’s old botanical name, Cochlearia armoracia, appears in the 1822 Flora Batava plate reproduced here. Kew recognises Armoracia rusticana as the accepted modern name. The plant’s kitchen identity is unusually direct: a pale root is grated to release a vivid condiment. The RHS records its continuing use in horseradish sauce. A dated botanical illustration supports the history of its recognition, while present-day sauce and dressing uses show how the same plant remains useful in a modern kitchen.
III. The Flavour
A sharp, clean, nose-tingling pungency rather than chilli-like warmth. Freshly grated root is especially forceful; its character fades after preparation and much of the flavour is lost in cooking. The flesh is firm and fibrous.
- Aroma

IV. Culinary Affinities
Contemporary flavour suggestions, distinguished from documented historical combinations.
Meat: Beef provides a rich background for its sharp pungency.
Vegetables: Beetroot, potatoes and cabbage offer sweet or earthy contrasts.
Fish: Oily or smoked fish can carry a small amount of sharp root flavour.
Dairy & eggs: Cream, yoghurt and eggs soften the immediate bite.
V. Companions in the Mortar
Dill and chives give a fresher herbal direction. Black pepper adds warmth without changing the root’s identity. Mustard reinforces pungency, so consider whether both are needed.
VI. The Alchemist’s Note
Wash and peel food-grade root, then grate only what you need for an immediate culinary use. Think of horseradish as an accent: a creamy or sweet background makes its sharpness easier to appreciate.
