DOES NOT WORK
Absolutely DO NOT BUY! This colouring DOES NOT WORK AT ALL... it literally makes whatevery you put it in look like grey/beige sludge. I wish I had read the reviews first. Absolutely shocking that this is still on the shelves.
Terrible for butter cream icing
Terrible. I used it in butter cream icing and it was not true to colour at all. The more colour you add the more runny the icing. Add more icing and you get paler colour. The colour is not at all like the colour in the bottle. Avoid.
Awful. Doesn't work.
Do not buy this awful product! After adding almost a whole bottle, I was not able to colour a cake for my daughter's birthday. Other brands have coloured the same recipe in just a few drops. Very disappointed and will have a disappointed daughter when she sees her rainbow cake is not coloured!
Excellent Vivid colour
Review from tesco.com
We have been adding this to water and playdough, the children have enjoyed watching these change colours!
