I made a Tarte au Citron today for the first time ever. I had some lemons I wanted to use up. I found a recipe online and here is a copied and pasted list of ingredients for the filling:
5 unwaxed lemons
275g caster sugar
4 eggs, beaten
300g unsalted butter
Please tell me that the 300g of butter was a mistake! That's more than a whole packet of butter. It must be wrong, surely!
