The Buttering and Glazing of Moulds

The Buttering and Glazing of Moulds

Created by Chef Juliette

Based on No. 2341, The Buttering and Glazing of Moulds, from Le Guide Culinaire (1907) by Auguste Escoffier

The smallest pâtisserie discipline decides whether a cake leaves its mould intact: clarified butter in every corner, followed by the lightest veil of dry flour or fécule.

Beurrage et chemisage des moules teaches one true thing before you touch the pan: release is made before batter ever enters it. Clarified butter must reach every corner, seam, flute, and central tube, then very dry flour or fécule settles over it in a veil. One bare spot is enough to hold the crumb and tear a cake at turning-out.

The classical pastry kitchen assumed clarified butter kept liquid, dry dusting flour ready, a pastry brush in hand, and ranks of moulds prepared for service. At home, warm a spoonful of clarified butter, prepare one mould, and catch the excess coating in a bowl. The brigade tray and dedicated butter pot are scaffolding and can go; the unbroken layer of pure butter and the thin, even chemisage must stay. One cook, one stove, one evening.

Do not mistake more coating for better insurance. Puddled butter and clotted flour make pale ridges on a cake, while a thin, uniform film releases cleanly and leaves the fine glazed crust promised by the method. Before the batter comes near, hold the mould toward the light and inspect every inside surface. That is the step that decides it.

Beurrage et chemisage belongs to the French pâtisserie workroom and the cuisine bourgeoise kitchen, with Parisian pastry practice giving the technique its most exact vocabulary. Metal moulds conduct heat beautifully but cling to egg-rich and sugar-rich batters, so generations of cooks answered with purified butter and a dry lining chosen for the cake: flour or fécule for biscuits, chopped or splintered almonds for certain richer cakes. The coating is not decoration added afterward; it becomes the fine glazed crust revealed at turning-out.

The technique, the tradition, and the story behind every dish.

Ingredients

clarified butter

Quantity

1½ tablespoons (22 ml / 20 g)

liquid but barely warm; clarify from about 2 tablespoons (30 ml / 28 g) unsalted butter if needed

very dry all-purpose flour or fécule (potato starch)

Quantity

3 tablespoons (45 ml / 24 g flour; 30 g fécule)

sifted

blanched almonds (optional)

Quantity

⅓ cup (80 ml / 35 g)

finely chopped or cut into splinters; use instead of flour or fécule when directed

Equipment Needed

  • Small saucepan for clarifying butter
  • Heatproof cup
  • 1-inch (2.5 cm) soft pastry brush
  • Fine-mesh sieve
  • Wide bowl or rimmed tray for catching excess coating
  • One 9-inch (23 cm) cake mould or 8 small moulds

Instructions

  1. 1

    Clarify the butter

    If starting with whole butter, melt it over the gentlest heat without letting it colour. Remove it from the heat, skim away the white foam, and let the milky solids sink before pouring the clear golden fat into a small cup. Leave every cloudy drop behind. If some solids escape into the cup, let them settle and decant once more; their water can turn the flour coating gummy.

    Ready-made clarified butter may simply be warmed until fluid. It should be barely warm, not hot enough to run into puddles.
  2. 2

    Prepare the coating

    Sift the flour or fécule into a completely dry bowl, breaking up every lump. The powder should fall freely from the sieve. If it feels damp or packs into little pellets, dry it for 5 minutes in a 250°F (120°C) oven, then cool it fully before use; warm flour would melt and disturb the butter film.

  3. 3

    Brush every surface

    Begin with a clean, dry, room-temperature mould. Brush clarified butter into the deepest corners first, then across the base, sides, flutes, seams, and central tube, if there is one. Aim for a translucent film without ridges or pools. Hold the mould toward the light and turn it slowly. If bare metal shows anywhere, dab that spot with butter; if butter gathers at the bottom, brush the excess back over the sides.

  4. 4

    Apply the chemisage

    Spoon half the flour or fécule into the mould. Turn and tilt the mould while tapping its outside so the powder travels over every buttered surface, adding more only if needed. Invert it over a wide bowl and tap decisively to remove all loose excess; the finished chemisage should resemble frost on glass, not plaster. If the coating gathers in wet clumps, wipe the mould clean and begin again with properly clarified butter. Ça se rattrape, and two minutes now are cheaper than a torn cake.

    For a cake that specifically calls for chopped or splintered almonds, sprinkle them over the butter instead of applying flour or fécule. Turn the mould until they adhere evenly, then tip away the loose pieces.
  5. 5

    Inspect and fill

    Look once more at the corners, flutes, and central tube before adding the batter. Patch any exposed place with the smallest touch of clarified butter and another breath of dry coating. Pour the batter toward the centre and let it spread naturally rather than scraping it repeatedly against the prepared walls. Bake and turn out according to the cake's own directions; the clean release begins with the work you have done here.

Chef Tips

  • Butter, not margarine or aerosol spray. Clarifying removes the water and milk solids, leaving a pure fat film that coats evenly without pasting the flour into damp patches.
  • Use flour for the usual chemisage. Fécule gives delicate biscuits a particularly fine, pale coating, while chopped or splintered almonds belong only where the cake formula asks for them. These are alternatives, not layers to pile together.
  • A soft 1-inch (2.5 cm) pastry brush reaches corners better than a broad silicone brush. If the mould is deeply fluted, work from the deepest grooves outward and inspect for loose bristles before dusting.
  • Do not leave a heavy flour coat for luck. Excess flour bakes into chalky ridges and obscures the cake's pattern; turn the mould upside down and tap until nothing more falls.

Advance Preparation

  • Clarified butter can be prepared up to two weeks ahead and kept covered in the refrigerator. Warm only the amount needed until it becomes fluid, then return the remainder to the cold.
  • A mould may be buttered and chemisé several hours before filling. Keep it in a cool, dry place beneath an inverted bowl so nothing touches the coating; avoid an uncovered refrigerator, where condensation can spoil the dry veil.
  • The flour or fécule may be sifted a day ahead and held in a tightly closed, completely dry container.
