Loose-set, intensely fruity, less sweet than a commercial jam.

Where this dish comes from

Preserving fruit in sugar arrived in Europe with Arab traders who brought sugar cane west through Persia and Egypt. Medieval apothecaries sold fruit conserves as medicine long before they were food; the word 'marmalade' comes from the Portuguese marmelada, a solid quince paste sold as a digestive.

Copper is the traditional pan because it conducts evenly and because copper ions strengthen pectin's gel — a piece of practical chemistry the confituriers of seventeenth-century France understood empirically centuries before anyone could explain it.

Christine Ferber, the 'fairy godmother of jam' of Niedermorschwihr in Alsace, is the acknowledged master of the small copper-pan set, and her jars are on the cheese trolleys of three-star dining rooms across Europe. June Taylor in Berkeley brought the same philosophy to American fruit.

How we make it

Shallow and fast. A deep pot needs long cooking to evaporate, and long cooking is what turns bright fruit into brown sweetness.

We test the set on a chilled plate with a fingertip, the way it has always been done. A thermometer tells you the temperature, not whether the pectin has taken.

Copper-pan set

1 day, start to seal

  1. 01Fruit macerated overnight in sugar so it releases its own syrup.
  2. 02Cooked fast and shallow in unlined copper — minutes, not hours.
  3. 03Set tested on a cold plate by hand, never by thermometer alone.
  4. 04Jarred at 104°C and inverted to seal.

On bread and butter, or against a hard cheese at the end of the meal.

THE INGREDIENT LEDGER

Every defining ingredient, named: who grew or caught it, where, when it was taken, what it has meant to the people who kept it, and what it does for you.

Why it is good for you
Peak-ripeness produce carries measurably more vitamin C and polyphenols than cold-stored fruit.
