This question has answers which explain the difference between vanilla essence and vanilla extract, and which tell you when you may want one over the other - if I am correct in thinking that "vanilla essence" is the same as "vanilla flavouring"?
My question is - in baking where colour is not an issue, how do I substitute one for the other? For example in a recipe that asked for 1tsp of extract, how much essence would I use in it's place?
