Celery root, also known as celeriac, is an awesome root highly common and popular in Europe but still waiting for its time in US. It is a different variety than regular celery (stalks). Its root has a bulbous shape and sometimes comes with its leaves on top that resemble giant parsley. It is best during the winter months, but could be found until late March here in the Bay Area. Most American recipes that I've come across recommend boiling and mixing with mashed potatoes or grating raw and adding to salads. Although both are fine ways of cooking with celery root, they're far from how we eat celery root in Turkey. Celery, kereviz in Turkish which comes from karafs in Persian, is cooked in meet stews and soups like potatoes, or in egg-lemon sauces similar to Greek avelomange sauce, but yet the most common way of preparing celery is the traditional olive oil cooking, i.e., cooked in olive oil with usually with carrots, potatoes, and peas, and seldom with quince and orange slices and served luke warm, like this recipe or this one .
Celery root with orange or tangerine juice is a "spin-off" from the conventional olive oil variety. The mixing of orange and lemon juices in this dish create a memorable and delicious tangy flavors.
When picking celery roots, avoid both very small and very big ones. You would lose half of the small ones to peeling and the big ones tend to be hollow in the middle. Pick mid-size celery roots, approximately grapefruit-size ones and feel their weight in your hand; they should be heavy. Once peeled celery roots darken fast, so always keep a bowl of water and juice of half a lemon ready to place the peeled roots. If you get them with the greens on top, save them for cooking and decorating.

It can go from half a lemon juice to one and a half. I love mine tangy and usually add juice of one big lemon, 2-3 tbsp). Also add 1/2 cup of water.
-Salt it to your taste.
