Thanks all for the advice - I'll try Tescos as prettycandles suggested. Here is recipe:
Jewish Chicken Soup w. Matzo Balls
To be made the day before needed.
(Serves 4 to 6)
1 large chicken, sectioned including giblets
pack giblets
3 large carrots, sliced
3 stalks celery plus handful celery leaves sliced
2 onions, roughly chopped
3 bay leaves
1 cup rice
3 potatoes, roughly chopped (optional)
salt to taste
pepper
Place chicken and giblets in a large saucepan and cover with water.
Boil with lid on but slightly open till chicken is cooked. Remove
chicken sections (leaving giblets) and set aside to cool. Then skin,
bone, and section chicken and return to pot. Add carrots, celery,
onions, bay leaves, salt and pepper and more water if needed and
boil for about 3/4 hour. Then add rice and potatoes, taste for salt
and add more if desired, and boil again for 1/2 hour. Set aside to
cool then refrigerate till the next day. Next day, skim off and
discard fat, then reheat soup adding prepared matzo balls if desired.
When serving, keep turning bay leaves back to soup if you don't
plan to use it all - they will add flavor.
Matzo Balls
2 eggs
1/2 cup Matzo Meal
1/3 teaspoon salt
Separate eggs. Beat whites until stiff then add yolks. Mix
matzo meal and salt and fold into eggs - gently. Put in frig
for 1/2 hour. Form balls - gently - and drop into boiling,
salted water or soup. Cover and cook 45 minutes.
