Can I freeze a cooked dish like shrimp jambalaya, even though the shrimp had been frozen before?
Marylyne G., Newport Beach, CA First of all the answer is yes, even though by the time you receive this answer your casserole would have been eaten or discarded. Your question though raises the overall issue of whether or not, in general, one can freeze a dish made with previously frozen ingredients. The answer is always yes because by cooking an ingredient you are transforming its structure and nature. Freezing raw ingredients prevents them from deteriorating as quickly as they might were you not to freeze them. However, once an ingredient is cooked, its structure is changed, and you can freeze it again, in its new form.
