|Don't do it!|
Today, I made puff pastry from scratch, and used it in a proper home-baked chicken pie. Which was, I might add, delicious. But I spent a long time in the kitchen, and it was devoured in 5 minutes. I could have bought a ready-made one in the supermarket. It would probably have been cheaper, too.
So that's my advice to any student getting over-ambitious in the kitchen. Stop, think, shop. You can bake proper pies when you've got more time!
