Nata, or Pasteis de nata is Portuguese for cream pastries. It's a tart-sized pastry with a crispy flaky crust and a pudding, flan like filling. It is not very sweet, and the good ones are warm, extra vanilla-y, and taste like they have alcohol in them.
I'm going to learn how to make these because they are so yummy. I had them 2 or 3 times yesterday and picked up 3 more at the airport.
