I love celeriac and I love potato leek soup and this had the best of both. I am thinking that frizzled leek (thinly slice leek and fry in a half inch of olive oil and let drain) would go beautifully on top of this instead of the chives.
This was a very comforting soup, on the first chilly day of autumn in the UK. I thought it was a nice way of combining some very classic flavours, like leek and cream. Still, I thought it could have had a bit more flavour. Something to make it stand out. I thought the maple syrup might add this touch, but I couldn't taste it at all. Maybe it needs to be drizzled on top of the soup, rather than completely combined.
