Portuguese Egg Tarts - Pastel De Nata

I finally found what works for a pastel de nata. Most people see these at Chinese restaurants, dim sum, etc. They are not like the Portuguese ones.  

These are a little piece of heaven: delicious, eggy, custardy, and really sweet.   
I found a recipe there last summer, tinkered with it a bit, and made something really great. 
My dad loved them, too, so for his birthday I will make him a batch.  

They are like a small puppy, always requiring attention.   I have to remind myself to keep an eye on them.  Still, they are worth it.  A sprinkling of cinnamon makes them authentic, sadly my dad doesn't like it that way.   He said he grew up eating them naked, so his batch will be naked.
