Can I freeze uncooked pork chops that have been marinated overnight in a citrus-based marinade?

Thanks for the advise.

Use fresh pork to do this (not frozen-refreezing meats etc can destroy texture). And defrost in the fridge. I found this information about marinating insightful. Especially marinating length.

Yup. Just cook them as soon as they defrost.
