Seville orange marmalade recipe

Method

Step 1

Peel the skin from the oranges and lemons, chopping into 3mm strips. Put into a large pan.

Step 2

Place your piece of muslin cloth into a large bowl. Cut the oranges and lemons in half then squeeze the juice from the fruit over the bowl, dropping the leftover squeezed fruit (pith, pips and flesh) into the muslin.

Step 3

Lift the muslin out of the bowl, gather the sides and squeeze any remaining juice into the bowl. Tie the muslin together with string to keep the fruit in and form a bag.

Step 4

Place the muslin bag in the saucepan with the peel. Add the squeezed fruit juice and 2.5 litres cold water to the pan.

Step 5

Heat until boiling, then reduce the heat and simmer for 2 hours, until the peel is tender. Put a few saucers in the fridge to chill.

Step 6

Remove the muslin bag and squeeze all the sticky juice from the bag into the pan.

Step 7

Measure the contents of the pan in a jug (include the shreds and liquid). Return to the pan and add 450g sugar for every 500ml liquid.

Step 8

Gently heat for 15 minutes, until the sugar crystals have dissolved. Increase the heat and boil rapidly for 15 minutes.

Step 9

Test that the marmalade has reached setting point by putting a teaspoon of the liquid on a cold saucer and gently pushing with the back of the spoon. If the liquid starts to wrinkle, setting point has been reached. If no wrinkling happens, keep boiling and re-test every 10 minutes. Turn off the heat as soon as you reach setting point.

Step 10

Leave the mixture to stand for 15 minutes. Stir gently, then carefully spoon into warmed sterilised jars. Put the screw lids on while the marmalade is still hot and turn upside down for 5 minutes to sterilise the lids (or boil the lids for a few minutes and leave to dry before use).
