Tips

Fill tins about two-thirds full for the best rise. Overfilling causes spillage, underfilling gives a flat result.

Temperature stays the same when changing tin size. Only the ingredients and baking time need adjusting.

Always check doneness with a skewer 5 minutes before the calculated time, especially with unfamiliar tin sizes.

Deep tins (3") need lower temperature and longer baking to cook through without burning the outside.
