As well as making the caramelised white chocolate cupcakes the other day I made some lemon yoghurt cupcakes - these ones - to make sure there would be plenty of cake to go around at work. I also wanted to experiment a little with using the fabulous Kapiti Kitchen cordials in my baking. Unfortunately due to the silly mistake I made with the white chocolate cupcakes the first time around I was running short on time. Since I'd already messed up one batch of cupcakes I decided to stick with the original recipe for the cupcakes, and play with the icing instead.
The batter took pretty much no time to put together - I used buttermilk instead of yoghurt this time as I had some left which needed using up, and I couldn't tell the difference - though I'm far more likely to have leftover yoghurt than buttermilk!
As an aside, while I was baking I thought I'd try out the lemon, lime and bitters cordial (my favourite so far, by the way) - I had asked Mr Caketo get some soda water from the supermarket so got it out to make up my drink - and check out the label; "Flavoured Soft Drink" indeed... Not sure when sodium bicarbonate started being a beverage flavour!
I figured I'd use the fruit syrup to make the french meringue buttercream recipe I make most often. I knew that it would take some experimentation to get the water/syrup/sugar ratios right, since the syrup is already some combination of water and syrup. I reduced the sugar by about 10g, but it wasn't enough - though I whipped up the eggs and drizzled it in as normal it didn't whip up - the syrup didn't lend the structure it normally does, so I suspect the ratios affected the boiling temperature and therefore the chemical composition. Woah, that's a bit in depth... Anyway, basically, it didn't work! By this stage it was about 9.45pm so in the interests of my sanity (particularly given the sleep deprivation resulting from a failure to adapt to Daylight Savings) I gave up taking photos and mad some emergency cream cheese icing. I added a couple of tablespoons of lemon and ginger cordial and zest of one lemon, and it was a hit, although the ginger was subtle to the point of being unnoticeable if you weren't looking for it. Not necessarily a problem, but if you were after a significant ginger hit this isn't the way to do it.
These were also a pretty huge hit with my workmates - I think cream cheese icing makes everyone happy, and having a bit of extra zing certainly wasn't detrimental. Was definitely nice to have a bit of affirmation after the failures - I guess I'm all good until my colleagues find this and discover my sneaky secrets! ;-)
