Should you marinate and baste food in the same marinade?

No, you should not marinate and baste food in the same marinade. This is because the marinade has likely come into contact with raw meat or fish, which could contain harmful bacteria. Reusing the marinade as a baste would contaminate the cooked food with these bacteria. To baste, it is best to create a new mixture that does not contain raw meat or fish and is safe to heat and brush onto the food during the cooking process.
