I do so agree with the K.I.S.S. method. My 2 last mixes were one 5 and one 6 flavors. I won’t mix anything over 7 but to go over 5 isn’t normal of me.Here lately I have been having more hits than misses with my diy mixes.
If a recipe calls for more than 5 flavors, it's off my list. To be honest I don't get the layering that some mixers talk about. All of my mixes are now steeped for 6 weeks, used to do 4.
I have adopted the K.I.S.S. philosophy for my mixes.
