Celery Basics

Some ideas with what to do with celery:

Raw
plain or with dips such as hummus, tahini, peanut butter, almond butter, labane, are all great.

In Soups
If you plan on keeping it around for a soup stock, you can freeze the stalks and keep it in a well sealed ziplock. This will take away the crunch from the celery, but this wont matter for a soup.

The Leaves
make a great garnish. You can eat them in salad, or mix them into a tabouleh.
