With a cookie cutter or rim of a glass, cut rounds from the pastry. Place rounds onto the tray and prick the base of the pastry a couple of times with a fork. Cook in the oven for 5 minutes, remove and with the base of a rolling pin, squash down any puffy bits that are appearing. Place back in the oven and cook for a further 10 minutes.
Lightly cook the onion for 5 minutes, add the garlic and cook for a further 2 minutes. Take off the heat and let cool slightly.
In a bowl place all the ingredients, including the onion mixture and pine nuts, stir till well incorporated.
The easiest way to fill each tart shell is to place all the mixture into a large zip lock sandwich bag, snip off a small corner and pipe the ricotta filling into each one.
Cook for 20 minutes or till puffed up and firm to touch.
