If the dough is too dry add more butter (or a splash of milk) to bind. If the mixture becomes too wet add some more flour.
I don't get this recipe. How can you add the same amount of flour and butter and expect breadcrumbs? Unless you are mixing it in a freezer of course. Then you add the other dry ingredients and it is supposed to make a dough! Perhaps this one is too advanced for me. - 13 Dec 2015
Absolutely delicious! I made this in a processor; next time, I'll put a bit more flour in, then whizz the dry ingredients together before adding the butter. There will definitely be a next time! - 08 Sep 2015
