I Picked, Processed Horseradish This Summer & It Tasted Very Bitter…had To Toss It Out. Is It An Issue To Pick While It’s In G

Question

rowing season? The horseradish has been in place for 6 years or so. I have not seen anything related to bitter horseradish on websites.

Answer 1

Research shows not to harvest until late fall or early spring before new growth resumes. So harvesting time may have been an issue. I also read to avoid any green roots while harvesting or after peeling, that it could be bitter. Did you encounter any green tinge on your roots?

Another reference said once cut or grated, the oils in the root degrade and become bitter if not used immediately or vinegar added to stop the degradation.

Also older roots become woody and not useable. So there are several ways to get bitter horseradish.
