A twist on celery soup. Leave out the haddock if you like (it's just flaked over the top)
Want to see what this recipe costs at different supermarkets? Compare in one place here:
'As the haddock is just flaked over to finish, you can leave it out if the kids aren’t keen. Also, if you want to make this soup vegetarian, simply omit the haddock and make the soup with vegetable stock.'
The celeriac soup can be made and the haddock poached 2 days in advance or up to a month ahead and frozen – defrost both completely before reheating
