Sizes

...I'm a bit OCD with cake mix amount. I don't have any left overs. The mix is calculated to fill each tin with the correct amount. Each muffin will be weighed out etc....so they all get the correct cooking time and they are all the same size.

Good gracious! The only time I've seen or heard of doing that is on the GBBO where precision really matters. 

I just dollop about the same amount into each muffin case, I use a tablespoon for muffins and a dessert spoon for fairy cakes (why are they called that I wonder). As for large cakes, I use the nearest size to the recipe, since for some reason my sandwich tins are  6 1/2", 7 1/2" and 8 1/2".  I inherited them from my mum. The deeper  (much older) loose bottomed tins are regular sizes and I've never measured the square ones - the one I use mostly looks about 7" square - perfect for my flapjack recipe.


I also still have some bits and bobs bought for school housecraft lessons in the sixties, including a cake turntable which really is not much use, a set of rings for making a chequerboard cake, and a charlotte rousse tin (used one time only).
