So, can you put a clay pot in the oven? Yes, if you respect its rules. Don’t be a bully. Soak it. Warm it slowly. Don’t shock it. Treat it like a grumpy old relative who makes the best cookies. You have to follow their way, or the cookies are ruined.
Go ahead. Try it. Worst case? You get a broken pot and a funny story. Best case? You make the most soul-hugging meal of your life. Either way, send me a photo. I’ll be over coffee.
