Basically, this is a cheesecake in a tart shell. The use of lemon zest is very interesting, and it produced a great citrusy flavour. I had a bit of trouble working with the pastry, but it obeyed me in the end. I also left the tart in the oven too long, giving it a brown surface, but it did not affect the taste.
I have been and will be making a lot of tarts, small and big, these days. This was so nice, but next time I would dust it with a little caster sugar, just to balance out the sourness. I say this year's Winter was awesome, and Spring's gonna rock!
