There is no alcohol in my recipe but if you prefer, add 2-3 tablespoons of Marsala, rum or sherry (or other alcohol of your choice) to the coffee before dipping the biscuits. The eggs must be very fresh or the cheese mixture becomes runny. Ideally prepare half a day ahead. Lasts up to 3 days, refrigerated and covered. Note: contains raw eggs.
Method
Pour the cooled coffee into a shallow bowl and add the milk.
Beat the yolks with 3 tablespoons of sugar for a couple of minutes until pale and creamy, in a bowl with a electric beaters or in the bowl of a stand mixer fitted with the paddle attachment.
Add the salt and stir.
