Celery may be obtained from last of July until April. It is best and cheapest in December. Celery stalks are green while growing; but the white celery seen in market has been bleached, with exception of Kalamazoo variety, which grows white. To prepare celery for table, cut off roots and leaves, separate stalks, wash, scrape, and chill in ice water. By adding a slice of lemon to ice water celery is kept white and made crisp. If tops of stalks are gashed several times before putting in water, they will curl back and make celery look more attractive.
