Tips and Tricks 

  • It’s important to use a pot with a thick and sturdy bottom to prevent the milk from scorching or sticking to the pot during the cooking process.
  • Cooking the milk mixture over low heat ensures that it steams without boiling. This gentle heat prevents curdling and allows the custard to thicken gradually.
  • Adding hot milk to the custard powder and whisking it together in a separate bowl helps prevent lumps. This step ensures powder is that the custard fully incorporated into the mixture without forming too many clumps.
  • Place the icicle bags in a tall glass.  Pour the custard into the icicles bags with a funnel at the opening, this prevents the mixture from spilling and makes for more precise pouring.
  • When freezing the custard mixture, whether in icicle bags, ice molds, or a pan, ensure that they are placed on a flat surface in the freezer. This will help the custard freeze evenly. Avoid overcrowding the freezer to allow for better air circulation and faster freezing.
  • While the recipe includes cinnamon and nutmeg for a classic custard flavor, feel free to experiment with other spices or extracts such as cardamom, almond, or coconut. Adjust the quantities to your taste preferences.
  • If this custard mix is too thick or too sweet, adjust by adding additional milk, a little at a time.
