I like surprising combinations, and celery with roquefort was a very intriguing match I had to try out. Instead of walnuts you can also use pecans, depending on what you like and what is available. I mixed the roquefort with skyr to create the right consistency. Skyr is an Icelandic product, somewhere between yoghurt and cheese. I used it previously also in my creamy date snack with smoked mackerel. You can of course also use any other fresh cheese with a neutral taste.
