How do i know if a baking sheet is non stick?

Look for these clues:

* Labeling: The most obvious way is to check the packaging or the sheet itself. Look for words like "non-stick," "Teflon," "PFOA-free," or "ceramic coating."

* Material:

* Aluminum: Some aluminum sheets are non-stick, but most are not.

* Stainless steel: Stainless steel sheets are generally not non-stick. However, there are some stainless steel sheets with non-stick coatings.

* Silicone: Silicone baking sheets are inherently non-stick.

* Surface: A non-stick surface will look smooth and evenly coated. There shouldn't be any rough spots or inconsistencies.

Test it out:

* Water bead test: Drop a small amount of water onto the surface. If it beads up and rolls off easily, the surface is likely non-stick.

* Touch test: If you can feel a slight texture, it's probably not non-stick. A truly non-stick surface will feel smooth and slick.

Important Notes:

* Even "non-stick" sheets require some care: Don't use metal utensils or scrub with abrasive cleaners.

* Over time, non-stick coatings can wear down: You may need to replace your baking sheet eventually.

If you're unsure, it's best to err on the side of caution and assume the sheet is not non-stick. You can always use parchment paper or a silicone baking mat to prevent sticking.
