The Verdict:Different, but not bad!
The flavour is a bit different from what we normally pair with chocolate today. Lemon and cinnamon is not what my tongue prefers, but I got used to it as I tasted and after finishing one tart, I think I could definitely eat another.
I had an issue with the chocolate filling not setting thickly, as I think it probably should have. That was probably because I didn't cook it enough and/or it needed more eggs. I like to round way down with eggs in historical recipes because I really hate eggy taste.
I used these pre-made puff pastry shells because I was feeling lazy (and Mr. Man picked those up instead of the tart shells haha), but I think puff paste tart shells would have worked way better.
Oh! I should add that I didn't add the diced lemon peel...I forgot about that and only had one lemon. I'm also not sure if the recipe meant fresh lemon peel (since its already in the recipe) or candied lemon peel. I imagine this can't have made much different flavour-wise, as there was already lemon in the filling.
Overall, this is a lovely recipe and although it may be a bit of an acquired taste, its good!
Edit: After sitting out for a while they did get firmer, and after being in the fridge the tarts became quite firm.
