Here's the results with the fine-tuned recipe:
The verdict - the egg tarts tasted better as they aren't as sweet as those I made in my 1st attempt, and well, they definitely look a lot better, not that Portugese, haha!!! However, I think there's still room for improvement as the tarts are kind of wobbly unless they are stored in fridge. Hmm... how to make the pastry a little bit harder or firmer?
