Makeahead: You can make most of the elements of the tarts and pies in advance. For instance, you could make the pastry ready in the pie dish and freeze it before cooking it. You can make the fillings and store them in the fridge for a couple of days. Then on the day, you want to serve the tart, style and add the topping. Please refer to the instructions for each individual dessert.
How to store: Most of these desserts keep for 1 day in the refrigerator or on your kitchen counter under a cake dome.
How to freeze: Most pies and tarts don't freeze well. They tend to absorb moisture and get soggy. You can however prepare the shortcrust pastry base in advance, place it into the pie dish and then freeze it before cooking it.
