Notes
Tips
Place your mixing bowl in the freezer for a few hours before whipping the cream. If the bowl isn’t cold enough, it can take longer for the ice cream to set.
Your freezer’s coldest area is probably in the back. Store your ice cream there for a quicker freeze and to store.
Pull your cream out of the fridge right before you use it. It won’t whip up quickly if it is warm.
