Cooked gumbo in cast iron dutch oven and the seeds okra turned black Is it safe to eat?

It's most likely safe to eat. Here's why:

* Blackening is normal: Okra seeds can turn black during cooking, especially when simmered for a long time. This is a natural reaction and not a sign of spoilage.

* Heat and time: The heat of the cast iron dutch oven and the time it takes to cook gumbo can cause the seeds to darken.

* Flavor impact: While the color changes, it's unlikely to significantly impact the taste or safety of your gumbo.

However, it's good to be cautious:

* Smell and taste: If your gumbo has a bad smell or taste, it's best to err on the side of caution and discard it.

* Mold: If you see any signs of mold or other unusual growth, it's not safe to eat.

To be extra sure: If you're concerned, you can always taste a small amount to see if it tastes normal.
