Nog on the Rocks, Traditional Noche Buena Feast

It's a Filipino tradition to stay up late on Christmas Eve for the night-long celebration of the Noche Buena, before opening presents under the tree. 
Each year, my family and I would have Christmas dinner at the usual time and then eat some more at Noche Buena.

1 tsp caster sugar

60 ml Irish Cream
