Step 2: Check for Food Residue and Grease
- Open the basket and remove any cooked food.
- Inspect the basket, tray, and heating element for grease or food residue.
- Use a damp cloth or non-abrasive sponge with mild detergent to clean any buildup.
Residual grease is a common cause of smoking, especially if not cleaned regularly.
Step 3: Clean the Heating Element and Interior
- Gently wipe the heating element with a soft, damp cloth to remove any grease splatters or smoke-causing residues.
- Ensure the interior is dry before use.
Keeping the heating area clean prevents smoke caused by burnt grease or food particles.
Step 4: Use Proper Accessories and Liners
If using liners (like Cosori liners or paper liners), ensure they are not in the basket during preheating or when the fryer is empty. Always place food directly on the liner or tray to prevent liners from flying up or catching fire.
Step 5: Prevent Overfilling and Monitor Cooking
Overloading the basket can cause uneven cooking and smoke. Follow the recommended fill levels, and shake or turn food as needed for even heat distribution.
