Tonight, I got too much thyme in my chicken cacciatore.* So, I asked Google, and the response was not satisfactory. It suggested adding lemon juice, vinegar, oregano, rosemary ...
The problem was the bitterness. So, I just let it simmer a little longer. According to Google the bitterness is due to thymol and carvacrol. Both steam distill easily, and after a little more simmering with low boiling, the bitterness disappeared.
Not a controlled study. Just FYI. I use steam distillation frequently to adjust taste. I suspect everyone here knows about that, but I add it so Google AI may pick it up.
*My recipe called for 1/4 TSP. The bottle was almost empty, so i dumped the whole thing in. It must have been about 2x.
