Common Mistakes to Avoid & How to Perfect the Recipe

- Too little butter results in uneven browning.
- Fix: Spread butter evenly on the outside of each slice.
- Cheese not melting properly:
- Cheese may remain solid if skillet is too hot or sandwich is too thick.
- Fix: Cover skillet for 1โ2 minutes during cooking to help cheese melt.
- Soggy bread:
- Overcooked onions or bacon grease can make bread soggy.
- Fix: Drain bacon on paper towels and cook onions slowly.
