Six-Onion Soup

I love alliums so couldn't resist this. I had to make a half-quantity as there wasn't room even in my biggest pan for the full amount of leeks. Result is rich and creamy as it claims - I would be tempted to add a little sharpness next time, maybe in the form of a dash of tarragon vinegar. I'd also add more spring onions (aka scallions), sliced thinner, at the end.

Unless I can manage to grow some chives I'll probably settle for Five-Onion Soup next time and finish it with parsley. Weight for weight they were the most expensive ingredient by a mile.
