Today, I cooked curry again and had a big mistake.

　Today, I cooked curry again and had a big mistake. In a typical recipe, we will simmer curry for about 20 minutes, but I simmered curry too much. I was going to watch Dr. House during simmering curry, resulting, I infatuated with the drama and forgot my cooking. Curry got burnt and my pot became charred. I barely could eat curry near on the top of the pot, but unfortunately, I left the other portion. Although I washed the pot by scraping strongly, I couldn't take off the burnt deposit which stacks to the bottom of the pot. I was really sad because the pot was my birthday present.

  It is probably better to say "I got infatuated with the drama while the curry was simmering." If you say "while simmering curry," it sounds like you are still standing next to the curry and cooking it. But if you say "while the curry was simmering" you are not necessarily standing next to it.
  
  "Resulting" is better used like this:
  I got infatuated with the drama resulting in the curry getting burned.
  I forgot my cooking resulting in the curry getting burned.
