It's whatever works for you, really. If the "finger dab" technique works go for it. Some load CF directly in the tub, others use a scooper (or a snurdler, if you like ), just as some will face lather while others will use a bowl. As you can see there is no "correct" way

I will tell you that due to the thickness of CF it doesn't take much, a dab about the size of an almond should provide plenty of lather for a full 3 pass+ shave. And once you try it you'll be hooked lol
