Instructions
- 1
Preheat the oven to 150C or 130C fan.
- 2
Heat the caramel sugar with one tablespoon of water in a small pan until it melts into a deep amber syrup.
- 3
Pour the hot caramel immediately into a 1-litre loaf tin, tilting it to coat the base and lower sides.
- 4
Whisk the eggs and custard sugar gently in a bowl until combined without creating excessive foam.
- 5
Stir the sifted cocoa powder and crushed amaretti into the egg mixture until smooth.
- 6
Gradually whisk in the lukewarm milk, rum and cooled espresso.
- 7
Pour the custard mixture through a fine sieve directly over the caramel in the prepared tin.
- 8
Set the tin inside a deep roasting tray and pour boiling water into the tray halfway up the sides.
- 9
Bake for 40 to 45 minutes until the custard is set at the edges with a soft wobble in the centre.
- 10
Cool the tin completely to room temperature, then chill in the refrigerator for at least 4 hours.
- 11
Run a thin knife along the edges and invert the tin onto a lipped serving dish.
Chef's tips
Do not over-whisk the eggs, as excess air bubbles cause an uneven texture in the baked custard. Always ensure the water in the roasting bath is simmering hot when placing the dish in the oven.
Ingredient substitutions
- dark rum → dry Marsala wine or an extra shot of espresso
- amaretti secchi → gluten-free dry almond amaretti to make the dish gluten-free
Storage
Store covered in the refrigerator for up to 3 days.
Reheating
Serve chilled straight from the fridge; do not reheat.
Common mistakes to avoid
- •Baking at too high a temperature, which boils the custard and produces a rubbery, holy texture.
- •Attempting to turn the custard out while still warm, which causes it to collapse.
