This is my favorite recipe range for all times, and it is completely modifiable to your specific needs:
Lard (either alone or with the GV shortening below) 40-65%
GV shortening with animal and vegetable fats (tallow and palm) optional, but I like it 0-25%
Olive Oil 15-20%
Coconut Oil 10-20%
Castor Oil 5%
Superfat 5%
Sugar 14 g PPO (per pound of oil)
I would use straight lard to start (don't use the GV shortening at all). With the Olive Oil and Coconut Oil at 15% each. Then try the OO at 20%, then the CO at 10%, etc. Once you get the OO and CO sorted out to what you like, you can then try substituting some of the GV shortening for some of the lard, etc.
