Vanilla is a key ingredient in a lot fo ice cream flavours, and the quality of the vanilla that you use can make a huge amount of difference. Using real vanilla pods is expensive and a bit of a chore, so a lot of people use Vanilla Extract, which is cheaper and easier. Don’t get mixed it up with Vanilla Essence though! Vanilla Extract is a natural product, and the flavour is extracted from real vanilla pods. Vanilla Essence, on the other hand, is an unnatural flavouring developed using chemical processes. Stay away from it!
