Chef's notes

  • ·Do not skip the cold ageing: it hydrates proteins and stabiliser and clearly improves the texture.
  • ·The serving temperature depends on your recipe: if you formulate to a softer PAC than your freezer (say -11 °C with the chest at -18 °C), temper it for 5–10 min before serving; if the PAC matches your freezer, it can be eaten straight out.
  • ·Why formulate at -11 and not at -18 °C: even though your freezer sits at -18 °C, formulating at -11 makes the ice cream tastes better — at -18 it is so cold that the taste buds barely pick up the flavour and the fat is slow to melt in the mouth. And keeps better: ice cream formulated at -11 and kept at -18 has less free water, suffers less from Ostwald ripening (ice crystals joining and growing) and keeps its creaminess longer.
  • ·Keep your own notes: write down the POD and PAC that work best with your machine.
Result

The texture
spot on

Every spoonful goes through all four layers at once: the firm cream, the soaked sponge that gives way, the denser chocolate and the burnt yolk, almost a custard. The contrast between what cuts and what melts is the whole dessert.

The ingredients and what each does

Every ingredient has a technical job: cream brings fat and creaminess, milk powder raises the non-fat solids, the sugars set the sweetness and the freezing point, and the stabiliser controls crystal growth during storage.

Technique and controlling the numbers

Adjusting the POD (sweetening power) and the PAC (antifreezing power, given as a target temperature) lets you match sweetness and hardness to your taste and your machine. With the selectors in the side bar the formula recalculates itself and you will see how the amount of each ingredient changes.

Storage and common mistakes

Store at -18 °C in an airtight container and avoid freeze-thaw cycles. The commonest faults are not ageing it enough, too much sugar so it never freezes properly, and over-churning, which whips in too much air and wrecks the texture.

Assembled with these ice creams

The cake has two ice creams inside. You will find them here, with their balanced formula:

Sheet of sponge

  1. Whip the yolksWhip the yolks, the egg and sucrose (1).
  2. Flour, sprinkled inOnce it is well whipped, sprinkle in the previously sifted flour and baking powder and work everything in properly. Set aside.
  3. Whip the whitesSeparately, whip the whites with sucrose (2). Whip well. As it starts to thicken, begin adding the earlier mixture.
  4. Mix by handMix by hand, a little at a time and gently.
  5. BakePour onto a tray and bake at 180 ºC for 15 minutes.
  6. Cut out the shapesCut it to the size of the tub. It makes 2 sheets: cut the spare one, soak it in syrup and freeze it for another time.

Almíbar

  1. Boil for a minutePut the water and sucrose in a pan and boil for 1 minute. Set aside.

Layered assembly

  1. Layer 1 · cream ice creamMake a cream ice cream (8 % fat), pour it into the base and freeze it solid.
  2. Layer 2 · spongeLay the sponge on the cream ice cream, soak it well with the syrup cold and freeze it solid.
  3. Layer 3 · milk chocolatePour the milk chocolate ice cream over the sponge and freeze it solid.
  4. Layer 4 · burnt egg-yolk creamSpread 0.5 to 1 cm of freezer-stable candied egg-yolk cream over it, dust generously with sucrose and burn it with an iron or a blowtorch.
