It worked really well, the sweet potato soup. But we were out and about all weekend, so I put the remainder (a litre or so) in the fridge, and of course it went very gloopy.
So this morning, I fished it out, added a mugful of lentils and about the soup’s volume in water, together with a good teaspoon of harissa paste to warm it up a bit.
It’s been on a low heat for a couple of hours, and we’re going to consume it with toast for lunch.
