How to freeze celery
Choose the right stalks.
When you're planning to freeze celery, it helps to start with the best stalks. Select those that are crisp and tender because they'll be more likely to freeze well.
OPTIONS:
- Choose stalks that are firm and rich in fiber. While celery isn't usually dried out, it may have a little bit of moisture.
- Give the celery about 5-6 stalks of each type of celery. Celery needs to be fresh and whole to taste.
- Avoid stalks that have coarse strings when you're freezing celery. Wash and trim the celery.
- Avoid stalks with very heavy pieces of skin because they'll be overripe when frozen and will be hard to cut, which is hard to remove. Look for celery stalks with bright, green leaves.

answer: Avoid stalks that have coarse strings when you're freezing celery. Wash and trim the celery.
