My grandma always treated her cast iron pans like treasures. To her, they weren’t just kitchen tools — they were heirlooms, seasoned with decades of meals, laughter, and stories.

One afternoon, I grabbed one of her skillets to make dinner, thinking I could cook anything in it. She walked into the kitchen, spotted me, and shook her head with a smile.

“You can’t cook just anything in a cast iron pan,” she said.

At first, I thought she was joking, but then she sat me down and shared her wisdom.

What You Should Never Cook in Cast Iron

1. Acidic Foods (Tomatoes, Vinegar, Citrus)

Grandma explained that foods with high acidity — tomato sauces, lemon-based dishes, vinegar-heavy recipes — can strip away the protective seasoning layer. The pan might even take on a metallic taste that seeps into your food.

2. Delicate Fish

Light, flaky fish like tilapia or cod tend to stick to the surface and fall apart. Instead of a beautiful filet, you’ll end up with bits and pieces stuck to the skillet, and a mess to clean.

3. Sweet Desserts

If you bake a cobbler, pie, or cake in the same skillet used for garlic chicken or steak, you may end up with flavors crossing over. Cast iron absorbs and holds on to strong seasonings, so sweet dishes can take on a savory aftertaste.

4. Extra Stinky Foods

Garlic, onions, or heavily spiced dishes can linger in the pan long after you’re done cooking. While these are fine for savory meals, they may affect whatever you cook next if you don’t re-season the skillet.

5. Eggs and Sticky Foods (Until Well-Seasoned)

Unless your skillet is perfectly seasoned, eggs and other sticky foods will cling stubbornly to the surface. Grandma always said, “Cook eggs only when the pan is ready — it should shine like glass.”

Grandma’s Tips for Caring for Cast Iron

• Season it regularly. Rub a thin layer of oil over the surface and heat it to keep the protective layer strong.

• Clean without soap. Hot water and a stiff brush usually do the trick. Salt can act as a gentle scrub if needed.

• Dry completely. Cast iron rusts easily, so always towel-dry or heat it briefly after washing.

• Store it lightly oiled. A little oil prevents rust and keeps the surface smooth.

The Lesson Behind the Pan

As I listened to my grandma that day, I realized it wasn’t just about cooking. It was about respect — for tradition, for patience, and for the effort that makes ordinary things last.

Now, whenever I use her skillet, I don’t just see a piece of cookware. I see her wisdom and the love she stirred into every meal. And I remember her words: in life, just like in cooking, the things we value most need care and attention if we want them to endure.
