Why it works: Orange and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
To Preserve Oranges or Lemons in Jelly
Ingredients
Directions
Prepare the fruit
Cut a hole in the stalk of each orange or lemon, the size of a shilling, and scrape out the pulp without cutting the rind.
Tie each fruit in muslin and soak in spring water for two days, changing the water twice a day.
Boil the fruit in water until tender on a slow fire.
Make the syrup
Weigh two pounds of double-refined sugar and one pint of water for each pound of fruit.
Boil the mixture with the juice of the orange to make a syrup.
Clarify the syrup.
Skim the syrup well.
Let the syrup cool.
Preserve the fruit
Boil the fruit in the syrup for half an hour.
Repeat daily until the mixture is clear.
Make the apple jelly and finish
Pare and core some green pippins.
Boil the pippins in water until the flavor is strong.
Press gently with a spoon.
Strain the water through a jelly bag until clear.
For each pint of strained water, add a pound of double-refined sugar, the peel, and juice of a lemon.
Boil the mixture to a strong syrup.
Drain the syrup from the fruit.
Place each orange or lemon hole-up in a jar.
Pour the apple jelly over the fruit.
Cover with brandy paper.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oranges or lemons
- Provide the whole fruit that is cooked and preserved in the clear syrup.
- Double-refined sugar
- Sweetens the syrup and helps preserve the fruit and set the jelly.
- Green pippins
- Their pectin-rich juice is used to make the apple jelly that sets the preserve.
The step that matters
Repeat the syrup boiling daily until clear. Boiling the fruit in syrup on several days lets the sugar slowly replace the water in the fruit, which keeps it clear and firm. Boiling it all at once would toughen or break the fruit.
