Indulge in a coffee lover's dream! This Espresso Crème Brulee features a luxuriously creamy custard infused with bold espresso and a hint of liqueur. Finished with a crackly, caramelized sugar crust, it's a delightfully sophisticated dessert. Can be made a day in advance for easy entertaining. Enjoy with a shortbread cookie for dipping!
Preheat the oven to 140°C (280°F). Stand 6 oven-proof coffee cups or ramekins in a roasting tray. Fill your hot water jug and put on to boil.
Put the cream and milk in a heavy-based saucepan and heat slowly to scalding point, then take off the heat. Stir in the espresso coffee and liqueur, if using.
Beat the egg yolks in a large heatproof bowl until pale and creamy. Pour the hot steaming coffee cream on to the egg yolks, a third at a time, whisking well. Then whisk in the caster sugar. Strain this liquid through the fine-mesh sieve into a jug.
Pour the mixture into the coffee cups, dividing it equally. Put roasting pan into the oven and carefully pour the boiled water into the pan, until the water reaches half way up the sides of the dishes. Bake for about 45 minutes until custards are very lightly set on top. They’re done when the sides are firm, but the centre is still slightly wobbly.
Remove from the oven and allow to cool. Pop them into the fridge – they’ll firm up while they’re chilling.
When ready to serve, take them out of the fridge and sprinkle a teaspoon of demerara sugar evenly over the surface of each custard and caramelize with a blow-torch. Serve within 15 minutes.
