Hey guys. first time poster long time viewer. im in a bit of a sticky and frustrating situation. i started DIY mixing a few weeks ago and iv learned alot on my little journey. now im a little stuck with percentages when it comes to multiple flavours etc. i have a good chart for my TFA and CAP single flavour mixes, but what happens to the percentages when you want to add 3-4 flavours to a mix?? is 20% a good rule of thumb with a multiple mix?? and how do i know what my base flavour is? heres an example, .... just say i wanted to make hazelnut whipped cream, and they both have a reccommended single flavour mix of 9%. does that mean i put them both in at 9% each to make 18% or do i tone one down slightly?? i have great ideas for my own mixes but want a heads up on my multiple ratios. thanks you lovely lot
