Bombe Châteaubriand

Ingredients

Equipment Needed

• •1.5-liter bombe mould or deep round metal bowl
• •Ice cream maker
• •Sugar thermometer
• •Stand mixer or hand mixer
• •Blender and fine-mesh sieve
• •Cold spoon or small offset spatula

Instructions

1. 1

   Freeze the working pieces

   Freeze the ice cream maker bowl according to its instructions, usually for a full day. Put the 1.5-liter bombe mould, the mixer bowl, and the cream beaters in the freezer for 30 minutes before you need them. Cold equipment buys time and keeps both layers distinct; a warm mould lets the apricot ice slide before it can set.

2. 2

   Cook the apricot ice

   Combine the ¾ cup sugar and ½ cup water in a wide saucepan. Heat gently until the sugar dissolves, then add the apricots and simmer uncovered for 18 to 25 minutes, stirring more often as they soften. The fruit is ready when it has collapsed into a glossy pulp and a spatula drawn across the pan leaves a path for two seconds. This cooking is the dish, not brigade scaffolding: raw purée carries too much free water, so it freezes icy and tastes dull.

   If the purée remains loose, keep simmering. If it begins catching on the bottom, lower the heat and move it immediately to a clean pan without scraping up the darkened patch.
3. 3

   Purée, chill, and churn

   Blend the cooked apricots until completely smooth, then press the purée through a fine sieve. Set the bowl over ice and stir until thoroughly cold. Churn it until dense and softly mounded, like firm soft-serve, then work without delay. If the churner was not cold enough and the ice stays liquid, ça se rattrape: pour it into a shallow metal pan, freeze for 30 minutes, beat it vigorously, and repeat until spreadable.

4. 4

   Clothe the cold mould

   Reserve 1 cup (240 ml / about 220 g) of the apricot ice for the base. Use Another Method of Preparing Aspics de Filets de Soles (No. 916) as the referenced model for chemiser le moule, clothing the mould with an even layer. The original method turned a mould over broken ice; at home, spread the remaining apricot ice about 1.25 cm thick over the bottom and sides of the frozen mould, using the back of a cold spoon, then freeze for 20 minutes and fill any thin patches with a second pass. The fish preparation itself does not enter the dessert; its cold-setting mould technique is the point of the reference.

5. 5

   Cook the vanilla base

   Scrape the vanilla seeds into the egg yolks and put the pod in a small saucepan with the ⅔ cup sugar and ¼ cup water. Bring the syrup to a boil without stirring and cook it to 118°C or 244°F. Meanwhile, beat the yolks until pale and foamy. Remove the vanilla pod, start the mixer at low speed, and pour the hot syrup in a thin stream down the inside of the bowl, never directly onto the beaters. Increase the speed and beat for 7 to 10 minutes, until the pâte à bombe, the hot-syrup egg-yolk base, is thick, pale, and cool enough that the bowl no longer feels warm.

   If sugar crystals appear before the syrup reaches temperature, cover the pan for 30 seconds so condensation washes the sides clean. Keep skin and the mixer cord clear of the syrup; cooked sugar clings and burns.
6. 6

   Fold in the cream

   Whip the cold cream to soft peaks that bend rather than stand rigid. Fold one-third into the cooled pâte à bombe to lighten it, then fold in the remainder with broad strokes, turning the bowl as you work. Stop as soon as no white streaks remain. If the cream starts looking slightly grainy from overwhipping, fold a spoonful of the smooth pâte à bombe into it first; it will loosen and rejoin without losing the whole bowl.

7. 7

   Fill and freeze

   Spoon the vanilla preparation into the frozen apricot shell, pressing it gently into the curve so no air pockets remain, and leave about 1 cm clear at the rim. Soften the reserved apricot ice just enough to spread, then cover the vanilla completely and level it flush with the mould. Press parchment directly against the surface, wrap the mould well, and freeze for at least 8 hours. Separate cooks and holding tins were brigade scaffolding; the cooked apricot shell, vanilla pâte à bombe, and patient final freeze must stay.

8. 8

   Unmould and serve

   Chill the serving platter. Dip the mould in warm water for 5 to 8 seconds, dry it, and invert it onto the platter. If the bombe holds fast, wrap the mould briefly in a warm damp towel rather than soaking it again. Return a softening bombe to the freezer for 15 minutes before slicing. Cut with a long knife dipped in hot water and wiped dry between every slice, so the apricot shell and ivory centre show cleanly. Serve at once. À table!

Chef Tips

• •Use fragrant, fully ripe apricots. Out of season, frozen unsweetened halves picked ripe are the honest answer; cook them from frozen and allow a few extra minutes for their water to reduce.
• •A sugar thermometer removes guesswork from the pâte à bombe. The syrup needs 118°C or 244°F: below that the base stays loose, while syrup cooked much further sets into hard threads before it can join the yolks.
• •Use pasteurized yolks when serving anyone advised to avoid undercooked eggs. The hot syrup substantially warms the yolks, but the finished mixture is not held at a measured pasteurization temperature.
• •Serve the bombe without extra coulis or decoration. The orange shell around the vanilla centre is its own finish, and the first clean slice provides all the theater required. Cooking well is not cooking fancy.

Advance Preparation

• •Freeze a removable ice cream maker bowl for at least 24 hours, unless using a compressor machine.
• •The cooked apricot base can be prepared up to 2 days ahead and kept covered in the cold. Churn it immediately before clothing the mould.
• •The assembled bombe can be frozen up to 3 days ahead. Keep parchment against its base and wrap the mould well so the apricot ice does not collect frost or freezer odors.
