Hi there! i tried mixing food colouring into my buttercream today, i tried pink and ultra violet. but both had a peculiar taste. I wanted to find out if anyone has had the same probs and any advice on which colouring would be best to use, this is for cupcake toppings.

Never, but brand did you use.  I only use Chef Master and Ameri Color

ANever. I have had the expierence if changing the texture by adding too much color, but never the taste. Could it have expired?

I just bought the colouring from my local supermarket Sainsbury's in UK about a week ago. Its expiry is 2014 for both colours. I wonder why it happened then... I'll probably try a different branded food colouring. I ended up scrapping off all the buttercream and just eating the cake by itself

ASo sorry. Was it an all natural coloring? Sometimes those have a small taste.

well it states that the colouring is made from natural sources, not sure if thats where the taste is coming from.

Ah.. that is why I stick to those brands that are designed for cake decorating.

ahh, just wish i stuck to the cake branded colouring!

Is anyone familiar with 'Sugarflair Spectral Concentrated Paste Colour'? I might try this for colouring buttercream

Here is an idea.  Email the manufacturer at Sugarflair and ask them if their colour will interact with your icing ingredients. It's possible that something you put into your icing made those natural colours change taste.

Thanks BakingIrene, i've just emailed them now :-)

i only used butter and powdered sugar to make the buttercream, i didn't add any other flavourings, only the food colouring.
