We had these made for us by a generous consultant at the Festive cooking class a few days ago and just had to make some.
I found the dough was very soft and needed to go in the fridge before it could be rolled out. It seemed very strange to heat the mixture once you added the butter, as it had the effect of melting the butter almost fully and making the mixture very soft. The taste is great and the recipe makes a lot, I've only cooked half and there were 45 biscuits. They are lovely and crunchy, full of flavour and made the house smell great. Mine only needed to cook for 10 mins although that could be my oven as it runs hot, you can see in the photo some are a little overcooked. I'm planning on decorating some with royal icing and will post a photo of when I get that done.
I think I'll try the recipe that is already on the forum and see if they are much different.
