Tart pan size conversion? From one large tart to several small tarts.

There really isn't a simple formula - it's more complicated than simply putting cake batter into a different size pan or pans, because you have the crust forming the perimeter of each tart, which simply doesn't substitute on a volume basis as a filling or batter alone would.

That said, I would estimate that you'll get 4 smaller tarts. The filling layer may be a little thicker or it may be thinner than the full tart - as the crust could be.

Remember to greatly reduce the baking time, watching carefully lest the tartlets burn!

Let us know, please, how it turns out, if you try making the tartlets. Thanks so much. ;o)
