Hi Troupie
This caught my eye as I have just unearthed my Marcato biscuit press
Sorry I don't have a tmx recipe but I have the basic ingredients you could use together with the method from one of the biscuit recipes on here.
Basic Biscuit Dough:
500g flour
250g sugar
250g butter or marg
pinch of salt
60 to 80g milk (recipe says 2-3 oz milk-until the dough is soft)
2 teaspoons cocoa (optional)
3 egg yolks
Hope this helps
