For me baking. Every time I think "oh yes I shall make a beautiful lemon drizzle cake, some ginger snaps" I remember all the 'incidents' .
The incidents of burned cake on top that's not set in the middle; the £ in ingredients, the time spent. And then go and buy something ready made.
Buying the butter alone for any baking makes me think christ this isnt some great money saving hack.
Yes I know it's supposed to taste better homemade. I know a lot of folk find baking a great hobby/stress relief. For me it just works out an expensive, time consuming thing.
What other things have you made yourself where you've realised you'd have been better off just getting it from the shops?
(I know my baking could rectified by going on some cookery course or other... I'm beyond help, I've made my peace with it).
