Pasteis de Nata

Pasteis de Nata are delightfully sweet, mellow custard tarts that are all the rage in Lisbon. So if you are planning a trip to Portugal's capital you must see if you catch the addiction. Near the waterfront in the Lisbon district of Belem is the Antiga Confeitaria de Belem, which is famous for making thousands of these nuggets of indulgence a day. You can by them on the premises, but you won't get the recipe ! only three chefs at a time know it and they are sworn to secrecy, never get drunk on their own, and don't take bribes. however, they will give you little sachets of icing sugar and cinnamon to sprinkle on your Pasteis de Nata which is very very nice of them. In the summer they are open 7 days a week and open from 8.00am until midnight - so there is no excuse not get on down and let a little bit of Portuguese heritage into your stomach.

Although the recipe is secret you'll find an approximation at leitesculinaria.com

Belem is 6km West of Lisbon City Centre - so you may want to be more central, and settle for getting your tarts from less prestigous outlets - so try these sites for more general Lisbon accomodation:
