These lemon bars are from Leon Baking and Puddings : Book 3. I do enjoy lemon desserts but reduced the amount of sugar in the lemon filling by 50g as I thought 350g sounded an awful lot! I’m glad I did, because they were still fairly sweet. The recipe itself is very easy, although making shortbread by hand is a bit time consuming. With a food processor, you could get the preparation done quite easily in 15 minutes or so.
