Mojo Criollo that is. Pronounced MO HO, it is a Cuban marinade.
Made from Bitter Orange, Lemon, Garlic, Onion, and secret stuff.
Nobody, but nobody, does pig like the Cubans and this is their secret weapon.
Used to buy it by the gallon down in So FL. The gallons are hard to find up here, but the 24oz bottles are around. I've seen them, Publix or Blooms IIRC. Not expensive.
Marinate overnight (I put in a big zip lock and completely cover), then smoke as usual. You'll thank me later.

Also for chicken or beef. Chicken is ok, but neither my wife or I care for it with beef. Plenty of chickens and pigs in Cuba, but not much in the way of cows.
Give it a try, you'll be glad you did.
