There
are certain soups that are a must in a cook’s repertoire - French onion
is one and an excellent mushroom soup is another.
Our version is made with
a light chicken stock base and three varieties of fresh mushroom – white
button, swiss brown and Portobello – resulting in a good depth of
flavour. But do not worry if you can’t get all three varieties – if
brown buttons aren’t available, for instance, simply use more
portobellos. For a more intense flavour add a few shiitake or dried
mushrooms such as porcini (soaked in water first). Serve the soup
piping hot swirled with cream in winter or lightly chilled with a dollop
of yoghurt in summer. Garlicky pastry twists are the perfect
accompaniment.
INGREDIENTS:
50 g butter

2 bay leaves
finely grated zest of 2 lemons
2 teaspoons mustard powder

(Serves
6)
You will need: chopping board, cook’s knife, large saucepan,
blender, zester or fine grater, baking tray
STAGE
1:
Chicken
stock can be prepared well in advance if preferred and frozen until
needed. Or make it the day before and keep it in the fridge.
To
prepare
Chicken Stock: Place in a large saucepan 500 g chicken necks, 3 carrots, 3 celery
tops, 2 bay leaves, 1 large onion, 1 whole clove, 1 teaspoon coarse sea
salt. Add 2 litres cold water and slowly bring to the boil. (This draws
out the flavour from the chicken.) Remove any froth on the surface. Cover
and simmer gently for 2-3 hours. Strain, cool and skim off any fat on the
top.
(Makes about 1 litre)

STAGE
2:
Store
mushrooms in the refrigerator in a brown paper bag to help absorb moisture.
They should keep well like this for a few days. Cultivated
mushrooms do not need to be peeled. Just rinse or wipe lightly with a
paper towel.
Swiss
browns, sometimes called brown mushrooms, are a variety of white button
mushroom. They look similar but have a stronger, nutty flavour. Portobello
mushrooms, also known as brown flats or field mushrooms, are simply mature
swiss browns. They have a much stronger flavour than the immature button.
STAGE
3:
Heat butter
in a large saucepan and gently fry onion until softened. Add mushrooms,
reserving a few of each kind. Add garlic, herbs, zest and mustard. Cook
until mushrooms soften. Sprinkle
with cornflour and stir until well combined.
Blend or process until
smooth. Return to
saucepan and gradually add stock, milk and half the cream, stirring
constantly. Simmer 15 - 20 minutes.
Just before
serving briefly sauté reserved mushrooms in a little butter and fold into
soup. Swirl in remaining cream and season to taste. Serve with crisp herb
twists.
STAGE
4:
Herb
Twists: Place 400 g puff pastry sheets on a board lightly dusted with
flour. Combine 1 sprig finely chopped rosemary, 2-3 cloves crushed garlic
and about 1 teaspoon each sea salt and finely grated lemon zest. Pat
mixture evenly over pastry. Cut into thin strips and twist. Place on a
lined baking tray and bake 10 minutes at 180°C or until
golden.
