Thanks all, responses appreciated.
I've made this soup oodles of times, and always forget which way to go!
Nfk here you go, although I would add I tend NOT to weigh or measure, just sort of do it by eye and feel. (Some prefer thick soups, some thing, so it's your call!
Warning! Mr P will now not eat shop bought mushroom soup, he says after this is doesn't even taste remotely of mushrooms.
Butter for frying
Onion, peeled and finely chopped (why do they always say peeled in this book, only a complete numpty would use one unpeeled). I do both the onion and the mushrooms in the food processor.
At least 1/2 lb mushrooms, more the better. Cleaned and finely chopped
Chicken stock (I cheat and use a knorr cube or 2) quantity depends on amount of onion and mushroom, and personal preference re. the consistency, but start with about a pint and a half.
Flour, about 2 tablespoons, but again depends on the previous comments
Salt and freshly ground black pepper (if using stock cubes, I don't add salt)
Grated nutmeg, and a bay leaf.
Melt the butter, add the onion and mushrooms, cover and cook gently for a 5 minutes or so.
Add flour and cook for a further 2 mins, stirring constantly
Gradually add stock, plus a bit more water if it's looking too thick.
Bring to the boil stirring. Add seasonings. Lower heat, half cover and simmer gently for 20 mins. Remove bay leaf and adjust seasoning. Stir in cream to taste.
It does say to top each bowl with a good sprinkling of chopped parsley, but I don't bother.
