This question follows from this question. The answer there does not satisfactorily answer this question. Fish and chicken are not the same. It is possible that fat from chicken does not mix with oil, right?
When battered fish and breaded chicken are being fried in the same fryer, will fat from the chicken get mixed with the oil and attach to the fish? Will the remains of chicken still stick to the fish in the fryer, even though both the fish and chicken are battered and breaded, respectively?
