Professional Celeriac Purée with Brown Butter Recipe
This celeriac purée is a masterclass in texture and flavor balance, elevating the humble celery root to a fine-dining staple. By poaching the vegetable in a milk-cream aromatic bath and finishing with a dark beurre noisette, you achieve a depth of flavor that is both earthy and luxurious.

Method
Mise en Place: Peel the celeriac aggressively to remove all brown fibrous exterior until only white flesh remains. Cut into uniform 2cm cubes to ensure even starch breakdown.
Aromatized Poaching: Place celeriac in a heavy-bottomed saucepan. Cover with milk, cream, and thyme. Ensure the liquid completely submerges the cubes. Bring to a gentle simmer (approx. 90°C/194°F). Do not allow to reach a rolling boil, as this can split the dairy and result in a grainy texture. Simmer for 20-25 minutes until the cubes offer no resistance when pierced with a paring knife.
Beurre Noisette: While the celeriac cooks, place the butter in a small light-colored pan over medium heat. Whisk continuously as it melts and foams. Once the milk solids turn a deep hazelnut brown and smell toasted, remove from heat immediately and pour into a small bowl to stop the cooking process.
Emulsification: Drain the celeriac, reserving the poaching liquid. Discard the thyme sprigs. Transfer the hot celeriac to a high-speed blender. Add 60ml of the poaching liquid and the prepared brown butter. Blend on high speed for 2 minutes until perfectly smooth.
Refinement: For a true restaurant finish, pass the purée through a fine-mesh chinois or sieve using a ladle. This removes any remaining fibrous micro-chunks. Season with sea salt and the lemon juice to brighten the earthy notes. Keep warm in a bain-marie until service.
Notes
To simplify at home, you can skip the chinois pass, but the texture will be slightly more rustic and less 'velvety'.
Never use a food processor for this; the low RPM won't break down the fibers sufficiently. A high-speed blender is essential for the professional 'glassy' finish.
If the purée is too thick, add the reserved poaching liquid 15ml at a time while the blender is running.
Shock the bottom of the brown butter pan in cold water if it browns too quickly to prevent burning.
