Butters and Creams
Beurres et crèmes d’hors-d’œuvre prove that cold-table finesse is mostly timing: smooth good dairy, cover it closely, hold it cool, then season only as you dish so every spoonful keeps a clean edge.

Marinaded Cèpes
Created by Chef Juliette
Cèpes marinés teach the discipline of hot marinade and cold patience: small porcini kept whole, parboiled briefly, then steeped under sharp vinegar, oil, garlic, coriander, fennel, thyme, and bay.

Cèpes marinés (marinated porcini mushrooms) teach one precise lesson: a preserve tastes vivid only when the mushroom remains itself. Use very small, truly fresh cèpes, then respect the temperature sequence. The mushrooms are parboiled, drained, and cooled completely before a strained marinade meets them at a full boil. That contrast seasons them without continuing to cook them into softness.
The original recipe assumed two pounds of tiny cèpes arriving together, a broad basin, and a reliably cold larder. This home version halves that batch to fill one compact vessel and uses the refrigerator as the honest modern equivalent. The book connects the method to Cooked Marinade for Venison (No. 168), but gives cèpes their own sharper formula of vinegar, oil, garlic, bay, thyme, peppercorns, coriander, fennel, and parsley root. The large batch is brigade scaffolding and can go. The eight-minute parboil, five-minute aromatic boil, and five-to-six-hour steep are the dish, so they stay.
When they are ready, the little caps shine under their clear vinegar-oil coating, the woodland flavor sharpened rather than buried. The step that decides everything is simple: pour the strained marinade at a full boil over cèpes that are cool and thoroughly drained.
Cèpes marinés belong to the preserving table of southwestern France, particularly Périgord and Gascony, where Boletus edulis comes from oak and chestnut woods and must be dealt with while firm. Classical kitchens carried that woodland practice into the cold hors-d'oeuvre repertoire, and the word cèpe remained precise, meaning the prized bolete rather than any large mushroom. This preparation is a short refrigerated preserve, not a shelf-stable oil conserve: vinegar leads, oil rounds its edge, and the mushroom remains whole.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •4-quart saucepan for parboiling
- •2-quart nonreactive saucepan for the marinade
- •Fine-mesh strainer
- •1½-quart heatproof nonreactive bowl with cover
Instructions
- 1
Choose and clean
Choose cèpes small enough to leave whole, with tight undersides, firm stems, and caps free of wet bruises or insect tunnels. Brush away soil and trim only the dry base; don't soak them, because their sponge-like flesh holds water. If they are already soft or smell sour, change the plan. A marinade can preserve a good mushroom, but it cannot restore a tired one.
Fresh cèpes are Boletus edulis. Buy them from a trusted grower, market seller, or forager, and never cook a wild mushroom whose identification is uncertain. - 2
Parboil eight minutes
Bring the water to a full boil in a roomy saucepan. Add the cèpes, let the water return to a gentle boil, then cook for exactly eight minutes, stirring once so they cook evenly. A knife should enter the thickest stem with slight resistance while the cap still holds its shape. If a stem remains chalky, give it one more minute; if the mushrooms soften early, drain them immediately and spread them in one layer. Ça se rattrape by stopping the carryover cooking quickly. Do not rinse or squeeze them. Let them cool completely.

Boil the marinade
Make the mushroom-specific Cooked Marinade for Venison (No. 168) while the cèpes cool. Combine the vinegar, oil, crushed garlic, bay, thyme, peppercorns, coriander, fennel fronds, and parsley root in a small nonreactive saucepan. Bring to a controlled boil, then boil for five minutes. The oil and vinegar will remain separate, and that is correct; this is a marinade, not an emulsion. If it spits, lower the heat only enough to keep a steady boil.

Cover while boiling
Pass the marinade through a fine strainer, pressing the aromatics lightly, then return the strained liquid to the saucepan and bring it back to a full boil. Place the cool, well-drained cèpes in a narrow heatproof nonreactive bowl and immediately pour the boiling marinade over them. If the liquid does not quite cover, move everything to a narrower vessel or place a small nonreactive plate directly on top. Do not dilute the vinegar with water. Let the bowl stand for 30 minutes, then cover and refrigerate.
- 5
Steep and serve
Marinate the cèpes in the refrigerator for five to six hours, turning them gently once halfway through if the top layer rises above the liquid. Lift them out with a slotted spoon and serve cool, with just enough marinade spooned over to leave the caps glossy rather than swimming. They belong beside pâté, cold roast meat, bread, or a picnic spread kept properly chilled. À table!
Chef Tips
- •Small fresh cèpes are essential here. Large specimens have broad porous undersides that drink too much vinegar, while dried porcini cannot reproduce the whole, yielding texture this preserve requires.
- •Use white wine vinegar with at least 5 percent acidity. Homemade vinegar may be delicious but its strength is uncertain, and this is no place to guess.
- •The source calls simply for oil. A mild sunflower or grapeseed oil is the honest home choice because it lets the woodland flavor lead and remains fluid when chilled; a forceful olive oil changes the character of the preserve.
- •Parsley root tastes herbal and faintly earthy, not sweet like parsnip. If it cannot be found, use ¼ cup (30 g) firmly packed flat-leaf parsley stems; the marinade loses a little body but keeps its direction.
- •These cèpes are refrigerated picnic food, not a shelf-stable canned preserve. Carry them over ice and return leftovers to the cold promptly.
Advance Preparation
- •Prepare the cèpes in the morning for an evening meal, allowing the full five to six hours in the refrigerator. They become more assertively acidic if left much longer.
- •Store the finished cèpes completely covered by their marinade in the refrigerator and use within four days. This preparation must not be stored at room temperature.
- •For serving, remove only the portion needed about 15 minutes ahead. The oil may look cloudy when very cold; it clears as the mushrooms lose their chill.
