Have you ever thought about using a cheese grater when you make pastry or biscuits?
I’m one for shortcuts and saving time in the kitchen so one day I reached for the cheese grater when I needed to mix in butter into the flour when I use making biscuits.
The butter has to be cold and make sure you hold it using the butter wrapper so your hand doesn’t warm it too much as you grate.
It adds fine pieces of butter (or whatever other fat you’re using) to the flour so all you need to do is give it a simple stir to combine it and voila, you’re ready to add liquid to the mix.
Give it a try and I’d love to hear what you think.
