Roselle Jam

Why people make this jam

Roselle flowers — those vivid crimson hibiscus calyces — arrive in late summer and early autumn, and making a batch of this jewel-bright jam is one of the most rewarding ways to use them. The process is wonderfully simple: strip the red calyces from the green fruit inside, soak them briefly in salted water, chop, and cook with an equal weight of brown sugar until thick and glossy. The resulting jam is tart, fragrant, intensely flavoured, and looks like something from a high-end deli counter. It can be spread on toast, stirred into yoghurt, served alongside pork dishes or century eggs as a condiment, or eaten straight from a spoon. Roselle is traditionally considered to stimulate the appetite, support digestion, and generate fluids — it is particularly useful when the warm-weather months have left the digestive system sluggish. Fresh roselle calyces are available at Chinese or Asian grocers and organic produce suppliers when in season.

Method

1. Separate the deep-red calyces from the green inner fruit. Set the green fruit aside (see tips below for an alternative use).
2. Place the calyces in 300 ml of lightly salted water and soak for 20 minutes to clean; rinse well and drain.
3. Chop the calyces into small pieces.
4. Weigh the chopped calyces. Measure out the same weight of brown or black sugar.
5. Place the calyces and sugar together in a heavy-bottomed pot (a Corningware or earthenware pot works well).
6. Cook over low heat, stirring regularly, until the mixture thickens into a jam-like consistency. This takes approximately 20–30 minutes.
7. Remove from heat and allow to cool completely before transferring to a clean glass jar.
8. Store in the refrigerator. The jam keeps well for several months.

Nourilo’s Tips

• The inner green fruit that you remove from each calyx can be put to good use: simmer the green fruits in water for 20 minutes and give the liquid to children to drink — it is traditionally thought to help clear intestinal heat and support gentle diuresis.
• This jam keeps in the refrigerator for up to several months — Nourilo confirmed it stays good for close to half a year when properly sealed.
• Once cooled, the jar makes a thoughtful and genuinely delicious gift — far more personal than an imported chocolate box.
• A small spoonful alongside a plate of century egg and pickled ginger is a classic pairing that showcases this jam at its best.
