Can I freeze the cauliflower and Roquefort soup?

Yes you can.

Make the soup to the serving stage, but omit the crème fraîche and chives. Cool at room temperature. Freeze in a plastic container with tight fitting lid, allowing enough headspace for expansion. Freeze for up to 3 months. Defrost in the fridge overnight and reheat thoroughly, stir in the crème fraîche and serve garnished with chives.

Kind regards
