I would love to pretend that I have reusable, pre-cut liners for all my cake tins that I wash after every use and pop back in the tins, ready to use next time. The reality is that it is quite a way down my list of priorities and I always use greaseproof paper. Lining round cake tins is a pain; the drawing round and the cutting out, which never ends up right anyway. However, I have found a cunning way of making it very quick and it always works. You don’t even need scissors for this, as you can just tear the paper where necessary.
Place your tin on top of the grease proof paper so that the edge of the tin lines up roughly with the edge of the paper. Cut straight down near the other side of the tin so you have a square which is roughly the diameter of the cake tin. You really don’t need to be accurate, as long as it is bigger than the cake tin.
Take the tin off the paper. Fold the paper in half, turn 90 degrees, then half again and once more. Turn the tin upside down and put the tip of the folded paper at roughly the centre of the tin.
Make a rough mental note of where the paper comes to at the edge of the tin. Take your scissors again and cut the paper at this point. Unfold and there you have it. A perfectly lined cake tin in about 20 seconds.
