Recipe video above. Celeriac is an unsung hero of the vegetable world! It makes a wonderful creamy Celeriac Soup that's an elegant near pure-white colour, and happens to be low carb. It's thick, creamy and comforting. Texture like potato but better flavour - tastes mildly like celery but with earthy, nutty undertones.Make it as a sophisticated first course for a dinner party, or just a cosy dinner for midweek.This easily makes enough soup for 5 people as a meal (with some crusty bread on the side!)
