Test Kitchen Tips
Cinnamon comes in two basic types: Ceylon and cassia. Ceylon cinnamon’s delicate, complex flavor is ideal for ice creams and simple sauces. The spicy, bolder cassia cinnamon (often labeled simply as cinnamon) is preferred for baking.
Go for freshly squeezed lemon juice when preparing this recipe. Bottled lemon juice, which is from concentrate, won’t provide the same bright, fresh flavor.
