Final answer:
To prevent fillets from sticking to the grill press surface, apply a high smoke point cooking oil to the grill and press, ensure the grill is clean and well-maintained, and make sure fillets aren't too wet before cooking.
Step-by-step explanation:
When fillets are sticking to the grill press surface, it is important to take action to prevent this from happening, as it can affect food quality and the cooking process. The most common reason for fillets to stick is due to insufficient lubrication or a grill that is not well-seasoned. To address this, ensure that the grill surface is properly sprayed or brushed with a high smoke point cooking oil before heating and before placing the fillets on the grill.
It's also important to maintain a clean grill surface, as residual food particles can cause sticking. If the grill press itself is causing sticking, applying a light coat of oil on the press may help. Lastly, verify that the fillets are not excessively wet, as extra moisture can result in sticking and be sure to allow the grill to reach the proper temperature before adding the fillets.
