Due to the sugar content in the pastry, the pastry will caramelise upon baking. Hence, it is important to remove them from the muffin tin as quickly as possible, otherwise they will stick to the pan. If you are unable to remove them quickly enough, simply pop the muffin tin back in the oven for a few minutes and try again.
The tartlets taste best when they are warm, but they keep well under a covered dish for a few days.
All recipes on this website state temperatures for a regular oven (i.e. a conventional oven without fan). If you have a convection oven with a fan, please consult the manufacturer’s handbook on how to adjust the temperature and baking time accordingly.
