Challah bread
Challah is an enriched, sweet braided loaf traditionally eaten by Jewish families on a Friday night as part of the Sabbath meal, or on major holidays such as Rosh Hashanah
The day before you want to serve the soup, put the whole chicken and any extra bones in your largest lidded pan.
Halve the onions through the roots (leaving the skins on – they will add colour) and add to the pan with the remaining ingredients plus 2 tsp of salt. Add enough cold water to cover.
Bring the soup to a boil over a high heat, skimming off (and discarding) any foam with a big metal spoon. As soon as the water boils, turn the heat down to a very low simmer. Partially cover the pan and leave to cook gently for 1 hour 30 minutes, until the meat is falling off the bones.
Remove the chicken from the pot but continue to simmer the broth. Strip the meat from the bones, tearing some of the chicken into pieces to serve in the soup – save the rest to use in salads, sandwiches or pies.
Return the bones and cartilage to the pot and simmer gently for a further 1 hour-1 hour 30 minutes. Strain the soup into a large container or pan, discarding the vegetables and bones. Leave to cool completely then refrigerate overnight.
By morning, the fat will have risen to the surface – skim it off and refrigerate it. It can be used for fabulous roast potatoes and to make the matzo balls.
To make the matzo balls, use electric beaters to whisk the eggs with ½ tsp of salt and a few grinds of pepper until thick and creamy. Beat in the schmaltz – the mixture should now be light and foamy.
Mix the 60ml of chicken soup and matzo meal, and fold into the egg mixture – it will be very sloppy. Cover and refrigerate for at least 2 hours or overnight to hydrate the matzo meal and firm it up enough to be easy to handle.
Scoop tennis-table-ball-sized amounts from the mixture and, with moistened hands, gently roll into balls. Put them on a plate.
Fill a large, shallow pan with water and add the chicken soup powder. Bring the water to a boil and gently lower in the matzo balls. Reduce the heat to a gentle simmer, cover with a lid and cook for 30 minutes – they will puff up nicely.
In the meantime, check the soup for seasoning – it may need more salt – add some of the reserved chicken to the pot, and heat it up.
When the matzo balls are ready, carefully remove them from the pot with a slotted spoon and place two or three in each bowl. Add the hot chicken and soup. Sprinkle with the chopped parsley leaves.
