The title of this should be ‘How to Mix Icing Sugar Without making your Kitchen Look Like Miss Haversham’s’, but it was a little long-winded!
When I first got my Kitchen Aid I quickly realised that when adding icing sugar to the bowl with a moving whisk in it was likely to make my entire kitchen look like an unexpected frost had crept over everything-as the whisk moves, the sugar acts like a fine dust which just goes everywhere! You will still be finding it days later in places like under the microwave, which is on the opposite side of the kitchen. I know this is the case with electric mixers in general, but there is a solution.
Firstly, never add the icing sugar when the whisk is in motion; that way only pain and much wiping down lies. When you have added the icing sugar-simply cover the whole mixer and bowl with a large, clean tea towel and start the mixer up again on the slowest setting. There is something a bit disconcerting about not being able to see your mixture as the machine ploughs on, but rest assured, it is easier than the alternative! After a moment, tentatively check underneath to see if the icing sugar has combined and if so, proceed as usual.
One more thing, make sure you wash the tea towel afterwards. I forgot once and wondered why all my wine glasses tasted like candyfloss.
