I purchased a package of annatto seeds from my local Asian market
some time ago with the intention of using them in a dish one day and put them
into my cupboard. I recently rediscovered the package and decided that I should
really do something with them. I found this recipe, Annatto-Rubbed
Pork Chops with Salsa Recipe at cookthink.com, and changed it into a
grilled pork chop recipe (without the salsa). Annatto seeds give a distinctive
color to a dish. For this recipe, pork rib eye chops are rubbed with a spice
mixture after being marinated overnight in a soy based marinade that I usually
use with the addition of lime juice.
Enjoy!
