I made this today. It would be perfect for a dinner party where only small serves were served as it is very rich because of the cream and butter. It's so smooth and luscious and the most magnificent green that it seemed a shame to spoil it with any decoration, so I didn't bother
IMO certainly not a soup to have if you want to have a big bowl of for dinner, but like i said for special occasions in small amounts it would be very impressive to your guests, and so simple to make. 4/5
