Christmas cake. Instruction says whisk (ha-ha) 8oz sugar and 8oz butter until "light and fluffy". Are they having a joke? That's like whisking bricks and treacle. Light and fluffy? I'm doing it all by hand - the ex nicked the machines.
Light and fluffy is a relative term, just do it until you're bored and your arms hurt (both of them). Make sure the butter is (warm) room temperature - if you've not had time or your house is cold, use the microwave carefully, a few seconds at a time.
Only Moosey will spot the irony of me posting on a thread with this title ... but anyhoo ... if you get a wooden spoon and squash the room temperature butter against the edge of the bowl with it (er - on the inside!), it'll gradually start to mix a bit with the sugar (that's certainly the way to get it started off at least). Good luck!
Now in a bit I'm supposed to fold stuff in keeping the precious air in the mixture. What precious air? Yes I beat the eggs and they're a bit bubbly, the butter sugar is a bit creamy. Says keep the mixer running.
