Getting ready to mix up my first recipe today and was just curious how much you all mix to sample the recipes. With the flavors I have on hand the only recipe I can find that I can make is HIC's Cocoa Cookies. Is this an easy one for a beginner? How many ml do you all make to sample? I was thinking like 4 or 5 ml, but when I put the percentages in the calculator on some of the flavors it says .02 ml or zero drops. Just not sure how to proceed. thanks...
