You’ll fall in love, I guarantee; the flakes are so light, that they melt in no time to make way for whatever goodness lies atop. And it's quick!
Place the butter and a mixing bowl with the flour and salt sifted in it, in the freezer for 40 minutes.
Take them all out and grate the butter atop the sifted flour using the course side of a grater. Dip the butter in the flour every now and then to prevent the butter from sticking to the grater. You could hold the end of the butter with gloves or mittens if the weather is warm and humid.
You can freeze the quick flaky pastry for later use. Let it thaw before you roll it out. If you have pastry flour in your pantry, you can use that.
