We're in the same ballpark. I'm usually between 50/50 - 60/40 using LorAnn's at 20%. I typically do a 5mL test batch with 1 drop of EM. If I like it after an overnight hot water bath steep, then I'll scale up to 30mL with 3 drops of EM plus/minus a drop or two depending on the sweetness of the test batch.
