Homard à l’Américaine
Lobster shells blaze red over fierce heat, brandy catches, and tomato-wine liquor reduces to a shining sauce bound with coral and cold butter. The lesson is simple: after the finish, never let it boil.

Mousse d’Écrevisses Cardinal
Created by Chef Juliette
Based on No. 977, Mousse d’Écrevisses Cardinal, from Le Guide Culinaire (1907) by Auguste Escoffier
Mousse d’Écrevisses Cardinal sets airy crayfish cream beneath glossy jelly, alternating tails, and black truffle. Keep it cold, double the red butter, and the dome unmoulds with its brilliant colour intact.

Mousse d’Écrevisses Cardinal (Cardinal crayfish mousse) teaches the cold kitchen’s strictest lesson: temperature is structure. The crayfish purée, red butter, jelly, and half-beaten cream must meet while cold enough to hold their body but fluid enough to fill every curve. Force won’t repair warmth.
The original assumed a saucier’s fish velouté, jelly made from stock never off the fire, a cold room, broken ice, and spare hands for forty crayfish. The salamander, useful elsewhere in the brigade, has no work in this cold preparation. Here, forty crayfish become sixteen, twelve garnished carapaces become five, a fine-mesh sieve replaces the tammy, and a compact metal mould and chilled platter replace carved ice. Those are scaffolding changes. Twice the red butter, the thick jelly clothing, alternating rows of tails, truffle, and the quick hot-water unmoulding are the dish and must stay. One cook, one stove, one evening of work, then a quiet night in the refrigerator.
When it is right, the dome gleams cardinal-red beneath clear jelly, black truffle showing through the coral mousse and the tails marching in opposite directions. Prepare and decorate the mould before finishing the mousse. If the bowl must wait while you arrange tails, the mixture sets unevenly, so that order is the step that matters most.
Mousse d’Écrevisses Cardinal belongs to the grand cold entrée tradition of Parisian classical kitchens, where moulded mousses announced their principal ingredient through colour and decoration before the first cut. Cardinal does not name a region or a clerical garnish; in the canon it signals the brilliant red of shellfish butter, intensified here by doubling the red butter and setting crayfish tails beneath clear jelly. The dish passed naturally onto celebration tables because the refrigerator performs the final work, making it a true preparation ahead rather than a last-minute display.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •2-cup (475 ml), 6-inch (15 cm) metal dome or Charlotte mould
- •Large bowl and fitted stainless-steel mixing bowl for an ice bath
- •Fine-mesh sieve to replace the tammy used by a brigade
- •Small pastry brush and flexible spatula
- •8-inch (20 cm) chilled silver or plain porcelain platter
- •Kitchen shears for trimming the carapaces
Instructions
- 1
Reserve the decorations
Follow Mousse d’Écrevisses (No. 976) through the cooking and shelling of the crayfish, using 16 medium crayfish for this four-serving Cardinal version. Choose 8 unbroken tails for the mould and the 5 finest carapaces for service. Trim the carapaces neatly, dice the remaining tails as the component directs, and refrigerate everything at once. Keep the bodies and cooking mirepoix with the component, because that shell-rich purée is its foundation.

Ready the service
Prepare the chilled serving arrangement from Mousselines d’Écrevisses (No. 970), scaled for the small dome and 5 carapaces. A cold 8-inch (20 cm) silver or plain porcelain platter set over a flat cold pack while you assemble is the honest home equivalent. The rice or semolina cushion and carved block of ice were brigade display scaffolding; they add no flavour and can go.

Clothe the mould
Use the prepared mould clothing from Another Method of Preparing Aspics de Filets de Soles (No. 916) to give the inside of a 2-cup (475 ml) dome mould an even jelly coat about ⅛ inch (3 mm) thick. Keep the remaining jelly half-melted, cool and syrupy rather than warm. Dip each reserved tail in it, then arrange the tails over the bottom and sides in superposed rows: point the first row left, the second right, and continue the alternation. Chill each row until fixed before adding the next.
If the tails slide, the jelly is too warm or the clothing is not fully set. Stop, chill the mould for 5 minutes, and let the dipping jelly thicken before resetting them. Ça se rattrape. - 4
Finish over ice
Complete the Mousse d’Écrevisses (No. 976) exactly as its entry directs, making the Cardinal change that defines this dish: use ¾ ounce (23 g) red butter, twice the amount in the scaled mousse. Work the purée over ice, fold in the half-beaten cream and diced tails, then fold in 8 truffle slices immediately before filling. The mixture should fall from the spatula in a thick, soft ribbon and remain cold against the bowl.
If the mousse grows loose and glossy, it has warmed. Return it to the ice and fold slowly until it regains body. If the jelly has begun setting it into lumps, hold the bowl over barely warm water for only a few seconds, fold until smooth, then return it to the ice. Do not beat it. - 5
Fill without delay
Reserve about ⅓ cup (80 ml / 80 g) mousse for the carapaces. Spoon the rest into the decorated mould at once, beginning around the sides so the mixture settles against every tail without disturbing it. Press gently with the back of the spoon to remove hidden air pockets, then level the top. Fill the 5 trimmed carapaces with the reserved mousse and lay one truffle slice flat on each.
- 6
Chill until firm
Cover the mould and filled carapaces without letting the wrapping touch their surfaces. Refrigerate for at least 6 hours, preferably overnight, until the mousse is firm through the centre and the jelly feels cold and resilient beneath a fingertip. Keep it at or below 40°F (4°C), and leave it cold until the moment of unmoulding.
- 7
Unmould with care
Dip the mould into hot water for 2 to 3 seconds, keeping the water below its rim. Dry the outside, cover it with the chilled platter, and invert both together in one decisive movement. Lift the mould vertically without twisting. Finish the chosen service from Mousselines d’Écrevisses (No. 970) by arranging the 5 filled carapaces around the dome, almost upright, and keep the platter cold until serving.
If the dome does not release, return it upright, chill for 10 minutes, and repeat the brief dip. If too long a dip softens the jelly, chill the mould until the surface resets before trying again. Ça se rattrape. Never shake it loose.
Chef Tips
- •Use live medium crayfish when they are sound and available. Whole frozen raw crayfish are the classical pantry’s honest answer out of season; thaw them under refrigeration. Peeled tails alone cannot replace the bodies and shells that give the mousse its depth, nor can they supply the carapaces.
- •The doubled red butter is not decorative excess. It gives Cardinal its name and its unmistakable colour. Do not correct a pale mousse with tomato or paprika; change the quality of the crayfish butter, not the dish.
- •Test the clear fish jelly before clothing the mould. A spoonful chilled on a cold saucer should set firmly enough to cut but still tremble. Jelly that bounces will make the mousse unpleasant to eat, while a weak jelly cannot hold the tail decoration.
- •Fresh black truffle is ideal. When it is out of season, use a small preserved whole truffle or good jarred truffle slices, drain them well, and pat them dry before they meet the jelly. The perfume will be softer, but the substitution is honest.
- •Serve the mousse properly cold with a dry Champagne or a mineral white wine. The bubbles and acidity cut through the cream and red butter without trampling the crayfish.
Advance Preparation
- •The mould can be clothed and decorated up to 6 hours before the mousse is finished. Cover it once the jelly is firm and keep it refrigerated so the tails remain fixed.
- •Fill the mould and carapaces the day before the celebration. The mousse sets more evenly overnight and unmoulds with greater confidence; serve it within 36 hours for the freshest crayfish flavour.
- •Unmould no more than 30 minutes before serving. Return the finished platter to the refrigerator, lightly covered, so the jelly retains its gloss and the mousse stays firm.
