If you see a dip recipe that you might fancy as a spread don't be scared of thickening it with breadcrumbs or beans to make it into a spread or add less liquid then the recipe says instead and it might work.
I made a Pea and mint dip into a spread last week. I don't have the recipe I based it on know as it was out of a library book, but basically as far as I remember it was pouring boiling water over frozen garden peas in a colander and then whizzing them with mint and water. I then added some breadcrumbs to thicken and left in the fridge to firm up. Odd, but tasty!
