Onion cut into cubes and fry with chopped garlic on the next. the butter in a saucepan with a thick bottom or pan, I do both. Until soft.

Celery root clean, wash and cut into cubes 2*2cm, like the potato.

Combine with onion and fry slightly (optional).

Pour the hot salt and pepper to taste broth.

Bring to the boil, put the Bay leaf and cook over moderate heat until the vegetables are tender (15-20 min.)

Once all is cooked - if immersion blender - all at once... e-e-e - blenderm )) if standing with a glass - cool it down and it blenderi ))) In the first embodiment, immediately add the milk or cream (that is), stir and give it brew for 3-5 minutes In the 2nd - heat, not boiling. That's all. Eat everything, including children!
