Some dishes are clingy by nature. When cooking such, don’t skimp on the butter or oil. It’s better to err on the side of generosity here.

It protects the pan and makes your food tastier.

Avoid Overheating

Patience is a virtue, especially with cast iron. High heat for too long is a no-go. It risks food sticking and damaging the pan.

Low and slow often wins the race.

Season, Then Season Some More

Even if your pan claims to be pre-seasoned, give it some love and additional seasoning. Regular upkeep will keep it at its non-stick best.

Smart Storage

Rust is the enemy. Store your pans in a dry place where they don’t play bumper cars. Space them out; they appreciate a little breathing room.

Choose Wisely What to Cook

Delicate foods and acidic adventures can be tough on your pan’s seasoning. If you venture there, know that a re-season might be soon after.

Water Is Not a Friend

Leaving your pan soaking is inviting trouble. Dry it thoroughly post-wash, and if you can, give it a quick heat on the stove to banish any lurking moisture.

Step	Action	Why
1	Season properly	Creates a protective, non-stick layer.
2	Clean gently but promptly	Avoids damage and maintains seasoning.
3	Use enough fat	Prevents sticking and enhances flavor.
4	Avoid overheating	Protects the pan and its seasoning.
