Hi Maggie, Great idea! I would always recommend a class in Lisbon – this is the city where the sweet originally comes from. Every town in Portugal has “convent sweets” invented in monasteries and convents, and the pastel de nata is from Lisbon. Lucky us! The best classes depends on how many people you have. If it is a small group, you can probably book using the links in my blog above, bigger groups you might have to reach out directly.
