I've just made a vast pot of this! It is delicious but has taken the best part of the morning so I wondered if a soup maker could make this as well as I have?
I don't suppose it would manage the gruyere toasts either!
Seems it’s now Harry’s uncle - the Earl of Spencer - having his turn at a “tell all” book.
I think the idea of adding a little sugar is to start the process. I prefer patience but I am now not able to eat onions at all - because of the natural sugar which seems very, very unfair!
