I seen a recipe for RY4, I was minus the English Toffee though so my recipe is slightly different. It's absolutely yummy though 
8 drops PA tobacco
8 drops Lorann Caramel
8 drops Lorann Butterscotch
15 drops Lorann Marshmallow
1 drop Lorann Vanilla Butternut
Mixed that together in a small 6ml bottle then added 5ml total of a 50/50 VG/PG Nic mix @ 20mg.
Plus 3 drops lemon juice for some added TH.
Nom nom nom!!
