Help!!! I've just made 3 batch of playdough for my sons class and in the first batch I put almond essence! It wasn't until it was done that I realised that if it contained nuts they wouldn't be able to use it as it's a nut free school. I used coconut essence in the next 2 batches so that's ok! Does anyone know if it contains nuts? It contains alcohol, water, glycerine and natural almond oil flavour but doesn't have a warning about nuts on it!
