*Alternatively, for tarts like in the photos, use a mini silicone muffin tray and press about 1 tbsp of crust into each muffin cup. You can either pour the filling into each tart shell, or for a fancier look, use a piping bag and pipe it in. For piping though, the filling needs to set overnight in the refrigerator so it can firm up. Once the filling is in each tart shell, let mini tarts set in the freezer overnight.
