Bombe Ceylan

Ingredients

Equipment Needed

• •1.25-liter metal bombe mould or deep freezer-safe metal bowl
• •Small heavy saucepan
• •Fine-mesh sieve
• •Sugar or instant-read thermometer
• •Electric hand mixer or stand mixer
• •Ice cream machine, or shallow metal pan for the hand-frozen method
• •Cold spoon or small offset spatula

Instructions

1. 1

   Chill the equipment

   Clear a level space in the freezer. Chill a 1.25-liter metal bombe mould or deep metal bowl for at least 30 minutes, and chill the bowl and beaters that will later whip the cream. A cold mould catches the coffee ice quickly instead of letting it slide toward the bottom.

2. 2

   Infuse the coffee

   Combine the milk, the cream for the coffee ice, and the crushed coffee beans in a saucepan. Heat gently until small bubbles gather at the edge, then remove from the stove, cover, and infuse for 20 minutes. Strain through a fine sieve, pressing the beans only lightly; squeezing hard releases bitterness rather than more useful coffee flavor. Return the infused dairy to the clean saucepan and warm it again.

3. 3

   Cook the coffee custard

   Whisk the four coffee-ice yolks with their sugar and salt until smooth. Pour in a third of the warm coffee dairy while whisking, then return everything to the saucepan. Stir continuously over low heat until the crème anglaise, a pourable custard, coats the spoon and reaches 82 to 84°C (180 to 183°F). Never let it boil. If a few grains of yolk appear, remove it from the heat immediately, blend briefly, and strain into a cold bowl. Ça se rattrape. Set the bowl over ice water, stir until cold, then cover and refrigerate for at least 2 hours.

   Draw a finger across the coated spoon. When the track remains clean instead of flooding closed, the crème anglaise has enough body.
4. 4

   Churn the coffee ice

   Churn the cold custard in an ice cream machine until thick, smooth, and pliable, usually 20 to 25 minutes. It should hold the mark of a spoon without becoming hard. Without a machine, freeze it in a shallow metal pan and beat it thoroughly every 30 minutes until evenly frozen but spreadable, about four rounds; the texture will be a little less fine, but the dish remains honest.

5. 5

   Chemiser le moule

   Chemiser le moule by spreading the soft coffee ice over the bottom and sides of the chilled mould in an even layer about 1.5 cm thick. The source preserves this coating motion through Another Method of Preparing Aspics de Filets de Soles (No. 916); that preparation supplies the moulding reference only, and no fish preparation enters this dessert. Use the back of a cold spoon to press the ice firmly against the metal, then freeze for 30 minutes. Hold the mould toward a light and inspect the shell. If any patch looks thin or cracked, press in more coffee ice and freeze again. Ça se rattrape. Reserve enough coffee ice to close the base.

6. 6

   Make the pâte à bombe

   Put the sugar for the pâte à bombe and the water in a small saucepan, stirring only until the sugar is evenly wet. Bring it to a boil and cook without further stirring to 118°C (244°F). If crystals gather before the syrup reaches temperature, add a tablespoon of water, cover the pan for 30 seconds so condensation washes the sides, and continue cooking. Meanwhile, beat the four filling yolks until foamy. With the mixer running at medium speed, pour the hot syrup in a thin stream down the side of the bowl, never directly onto the whisk. Increase the speed and beat until the mixture triples in volume, falls in a thick ribbon, and the bowl no longer feels warm, about 6 to 8 minutes.

7. 7

   Fold the rum filling

   Test the underside of the pâte à bombe bowl. It must feel cool, ideally no warmer than 24°C (75°F). If it retains warmth, set it over ice water and continue whisking; add the rum too early and its perfume leaves before the dessert reaches the table. Once cold, beat in the rum and salt. Whip the cold cream to soft peaks, fold one-third into the yolk base to loosen it, then fold in the remainder with broad strokes until no white streaks remain. If the mixture slackens because the base was still warm, set it over ice and fold gently until it regains body. Do not discard it.

8. 8

   Fill and seal

   Spoon the rum pâte à bombe into the frozen coffee shell, pressing it gently into the curve so no large air pockets remain. Stop about 1.5 cm below the rim. Soften the reserved coffee ice in the refrigerator just until spreadable, then cover the filling completely and scrape the surface level; this becomes the bombe's base when it is turned out. Cover tightly and freeze on a level shelf for at least 6 hours, preferably overnight.

9. 9

   Unmould and serve

   Chill the serving platter. Press a towel dipped in hot water and wrung nearly dry around the mould for 5 to 10 seconds, then invert it onto the platter. If the bombe resists, repeat with the towel rather than pulling or twisting. Should the surface soften too far, return the unmoulded bombe to the freezer for 10 minutes. Let it stand for 5 minutes before cutting with a knife warmed in hot water and wiped dry between slices. The coffee shell should cut cleanly around the pale rum center. À table!

Chef Tips

• •Choose coffee beans with chocolate, nut, or caramel notes, not a very pale, sharply acidic roast. The coffee must remain legible when frozen, because cold quiets aroma and sweetness.
• •Use a dark rum you enjoy smelling from the glass. The filling does not cook after the rum enters, so rough alcohol remains rough; good aroma matters more than a grand label.
• •A metal mould gives the cleanest shell because it conducts cold quickly. A deep freezer-safe metal bowl is the honest home equivalent, though the finished bombe will be smooth rather than fluted.
• •The hot syrup cooks the yolk base in the classical manner. When serving pregnant guests, older adults, small children, or anyone with reduced immunity, begin with pasteurized egg yolks.
• •Let the bombe rest only long enough for the knife to pass cleanly. If the center slumps rather than slicing, return it to the freezer for 20 minutes and try again.

Advance Preparation

• •The coffee crème anglaise can be cooked and refrigerated up to 2 days before churning. Keep it tightly covered so it does not collect other refrigerator aromas.
• •Assemble the complete bombe at least the night before serving. Once solid, wrap the mould well; it keeps for up to 1 week without losing its clean coffee and rum character.
• •The bombe may be unmoulded onto its chilled platter up to 2 hours before dinner and returned to the freezer. Cover it loosely only after the surface has hardened again.
