    Just happened to have fennel from my neighbour's home grown allotment. No celeriac/celery root until I go shopping in the morning so have done this recipe in two halves to make sure the fennel is as fresh as it can be - liked picked fresh this morning! Will cook the celeriac tomorrow, then blend together. Promises to be a great soup!

    This soup is absolutely delicious, it is warming and just the right thing for a cold January evening. Took no time to make, I let the soup simmer very slowly in the simmering oven of the aga, this can be done in any slow cooker to bring out all the earthy flavours of celery root and fennel. 5 stars from me!

    How can the celery root be replaced in this recipe? In my country (Argentina) celery root is not available. Tks!!

    While we have not tested it, you could try radishes instead. They lose their sharp, peppery flavor when cooked.
