Vegetable Purées
The reduction of cooked vegetables to a smooth, uniform mass — by food mill, sieve, or blender — then enriched with butter, cream, or both, and seasoned. A correct purée is silken in texture, intensely flavoured, and holds its shape on the spoon without weeping. It is not liquidised vegetable. It is the most refined form a vegetable can take, where cooking method, moisture management, and finishing are each deciding factors.

The Method
1
Steam the whole, unpeeled celeriac over steadily boiling water for approximately 45 minutes. It is done when a skewer meets no resistance at the centre — the flesh yields completely with no raw firmness.
2
Remove the celeriac from the steamer. Peel it immediately while hot. Spread the peeled flesh on a flat tray and place in a warm oven for 3–5 minutes to drive off surface moisture. The surface should appear dry and slightly mat — no visible steam or wet sheen remaining.
3
Pass the dried celeriac through a food mill or drum sieve while still hot. Work quickly and completely — the result should be a uniform, lump-free mass. No blender is used at this stage; a food mill or sieve only.
4
Season the purée now, before any enrichment is added. Fat masks salt perception: the purée correctly seasoned before butter will taste correct after butter; the purée under-seasoned before butter will taste flat regardless of what follows. Taste the plain purée and adjust with fine salt until the celeriac's flavour is clear and present.

THIS IS WHERE THE DISH LIVES OR DIES. Add the cold butter in small pieces, incorporating each piece completely before adding the next — in the manner of monter au beurre. The purée must not be so hot that the butter breaks to grease, nor so cool that it will not emulsify. After the first additions, take a small amount of purée between thumb and forefinger: correctly enriched purée is silken, coating, and slightly warm — no graininess, no visible fat separation, no roughness. If fat separates and feels greasy, the purée was too hot; nothing corrects it, and the enrichment stage must begin again from a correctly tempered base.

6
Warm the cream separately and add it gradually, tasting between additions. The cream's lactic notes should soften the celeriac's earthiness without eliminating it. Lift a spoonful and allow it to fall: the purée should drop in a slow, cohesive mass — like very thick custard — not run off as liquid nor fall in firm chunks. On the plate it should hold a gentle, rounded mound for 30 seconds before relaxing. If it holds rigidly without relaxing, add a little more cream. If it runs flat at once, return briefly to gentle heat to reduce slightly.
7
Pass the enriched purée through a fine sieve. Even after the food mill, this final pass produces the refined, service-level smoothness that distinguishes a professional purée. The result should be uniform and silken with no fibrous traces.
8
Taste a final time. The purée must taste intensely of celeriac — more so than any other preparation of the same vegetable. If it tastes primarily of butter or cream, the starting flavour was weak or enrichment was excessive. If truffle oil is used, add only off the heat, in drops, and taste immediately: the two aromatic families — celeriac's sulphur compounds and truffle's dimethyl sulphide — should amplify each other, not produce a single dominant note.
III
Quality Hierarchy
01
Reserve — Celeriac from a named grower, steamed the day it is lifted; butter from a high-fat cultured source; a few drops of genuine truffle oil whose aromatic compounds share chemical kinship with the celeriac's own sulphur family.
02
Estate — Good market celeriac, firm and heavy for its size; quality unsalted butter incorporated cold; double cream with distinct lactic character. The drum sieve used for the final pass.
03
Market — Standard supermarket celeriac, steamed with attention to moisture management; unsalted butter of ordinary provenance, still incorporated cold in pieces; cream added gradually with tasting.
04
House — Any celeriac steamed rather than boiled, moisture dried before puréeing, seasoned before enrichment, and finished through a sieve. The method intact — this is the minimum below which the result is not recognised as a correct purée.

Sensory Tests
◇Sight. A spoonful lifted and allowed to fall drops in a slow, cohesive mass — like very thick custard — and holds a gentle, rounded mound on the plate for 30 seconds before relaxing to a flat pool; neither running immediately flat nor holding rigidly without relaxing.
◇Sight. For green vegetable purées only: the colour is vivid, almost luminescent green within 30 minutes of making; olive or army green indicates the purée was held too long and chlorophyll has degraded.
◇Touch. A small amount of the enriched purée run between thumb and forefinger is silken, coating, and slightly warm — no graininess, no visible fat separation, no roughness; greasiness indicates the butter was added to a purée that was too hot.
◇Smell. The aroma is distinctly of the vegetable, not of butter or cream alone; the enrichment should carry and amplify the vegetable's aromatic compounds, not replace them.
◇Where it lives or dies. The butter enrichment, executed by monter au beurre with cold butter in small pieces at the correct temperature, is the point at which the purée acquires its gloss, silken mouthfeel, and unified flavour — too hot, the emulsion breaks to grease and cannot be corrected.
