I ran out of Capella's Lemon Meringue Pie flavor but I get similar results using CK or Lorran Lemon oil and marshmallow. I left out the Graham Cracker crust. I'm still lovin this lemon meringue flavor.
To make a 5ml @18mg/ml with a lot of lemon flavor(Lemon oil is strong, you might want to use less at first then add a drop if you need it):
2.5 ml 36mg unflavored (I always use PG)
.25 ml lemon oil(CK products, Lorrann, or other)
.75 marshmallow flavor (from just about anyone)
1.5 ml vg or pg without nicotine
the same recipe @ 24mg/ml:
3.3 ml 36mg unflavored
.25 ml lemon
.75 ml marshmellow
.7 vg or pg
The only difference besides the nic strength is how much vg you can add but IMO 20% or less of vg is plenty but if you like lots VG you might want to get your unflavored nic in VG.
