I've been looking through the forum (in fact, through the whole Internet almost) and unless I missed it somewhere, I can't find any place where flavour substitutes are consolidated in one place. Bearing in mind that flavour substitutes are - just like flavours themselves - subjective in nature, there are at least standard substitutions that make sense. So I have an idea. Was wondering if you fellow mixers would be interested in having a consolidated thread here where we can ask things like "TFA sub for FA Cookie" and have some input on what the best substitution would be and how the percentages would change accordingly due to strength. (In this particular example I'd imagine one would be bang outa luck as I haven't personally found any good cookie from TFA, but I digress). In most instances, the typical question here would probably be: "Guys, the recipes call for 5% FA Red Touch, can I safely sub it with TFA Strawberry?". Or some such. What do you think?
