Going to scream soon

bazzer - put a smear of liquid (not even a drop, your mouth will take ages to clear the flavour otherwise!) on your finger and gently lick it. As Perpetua says, nearly all of the flavourings we use were originally designed as food flavourings.
If I use a new flavouring, I make up 10ml of a test mix first. Any smaller quantity and I find it's not accurate enough and the flavours tend not to mix well enough - or maybe that's just me!
Start low - you can always add more drops, but you can't take away what's already there!
