I can best describe this dessert as:
- cohesively crumby and almost cakelike;
- only barely sweet;
- quite lemony but not tart;
- made of nuts but hardly nutty tasting;
- comforting and filling but not decadent.
English pies are altogether different. They're much less sugary and showy. I agree that this could be a good introduction to English desserts for anyone who's curious. I think the traditional Bakewell Tart might be an even better choice for a newcomer. I really like this tart, but it might act as ammunition for those who like to claim that British food is boring. This pie isn't bland, but it's just a nice simple lemony dessert. A Bakewell Tart has a more complex balance of sweet fruitiness and nuttiness.
I had two firsts while making this: I made my first lemon curd and my first traditional pastry piecrust. The curd came out great; I can't wait to have the remains on biscuits or toast. The crust is pretty nice. It's absolutely delicious along the vertical edge, but a little odd on the bottom. I think my dish was perhaps a little too big so the pastry at the bottom is a little too thin. If you make this, use a small pie dish if you have one.
