Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the calves' feet
Scald the calves' feet to remove hair.
Slit the feet in two and remove fat between the toes.
Wash the feet well in warm water.
Make the jelly
Place the feet in a stewpan with cold water and bring to a boil, removing all scum.
Boil for 6-7 hours.
Strain through a sieve into a basin and let it cool to set.
Once firm, remove fat from the top.
Clarify
Transfer the jelly to a saucepan.
Add 6 ounces of sugar and the beaten egg whites and shells to every quart of jelly.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Calves' feet
- Provide the gelatin that sets the jelly as they simmer.
- Loaf sugar
- Adds sweetness to the finished jelly.
- Eggs
- Whites and shells are added to the jelly to help clarify it.
The step that matters
Removing scum while the feet come to a boil. Scum left on the surface during the first boil can cloud the jelly and spoil its clarity. Skimming it off as it rises keeps the finished jelly clear.
