Tips: You can make the tiramisu the night before and just sprinkle the muscovado sugar over I hour before serving. If the muscovado sugar is a little clumped together, heat it in the microwave for 10-20 seconds to separate the granules. If you don’t have an orange liqueur why not try dark rum or Amaretto instead. The number of biscuits used depends on the type of dish and what brand the biscuits are.So that the chocolate doesn’t melt when grating place it in the freezer for 30 minutes before hand. RAW EGG WARNING: Exercise caution in consuming raw and lightly-cooked eggs due to the slight risk of Salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, top grade eggs with intact shells, and avoid contact between the yolks or whites and the shell.
