Combine all the marinade ingredients in a large bowl, and blend well. Add chicken breasts, and let marinate for 1 hour in the refrigerator, turning occasionally.
While chicken is marinating, prepare the Tropical Marmalade by combining in a saucepan all the Tropical Marmalade ingredients (except mint); bring to a boil. Reduce heat to a simmer and let simmer for 1 hour or until the mixture reaches jam consistency. Stir frequently to avoid scorching. Cool. Fold in fresh mint, to taste; set aside.
Remove chicken from refrigerator, and let drain. Combine macadamia nuts and bread crumbs in a shallow dish. Dredge chicken breasts in flour, then dip in beaten eggs, and then coat with the macadamia nut mixture.
In a heavy skillet, heat oil and butter over medium heat. Saute chicken for 6 to 8 minutes, turning once. (Add a litte more oil if necessary, since macadamia nuts may absorb oil.).
