Miyuki Kokubu’s Yuzu Preserve
Miyuki Kokubu, a marmalade maker closely working on the Japanese Marmalade Festival, is one of our gold medal winners at The Dalemain World Marmalade Awards and has given this special recipe to us to share with you.
Miyuki lives in Yawatahama, a port city in Ehime Prefecture, Japan, and on the hills that surround the area are many different varieties of citrus fruit, over 200 kinds that are mostly unknown here outside of the country. Though this recipe can be made with either grapefruit or pomelo, Miyuki uses an unusual citrus fruit called Yuzu, which has a fragrant sherbet-like flavour with a bright tang to it.
Japanese preserves are often very low in sugar compared to typical jams and marmalades found around the word, so they need to be bottled and sealed at a high temperature in sterilised bottles, then once open stored in the refrigerator. If you’re making them to sell make sure your label is correct according where you plan to sell them.
Miyuki runs an organic wellness and cosmetic company, Orange Le Cura, based in Ehime, specialising in products using the local citrus fruit.

Miyuki Kokubu’s Yuzu Preserve Recipe:
500g firm fresh yuzu, or grapefruit
About 300g granulated sugar
1. Wash the yuzu well, cut it in half and squeeze out the juice. Then divide it into 4 quarters lengthways and separate the skin from the pulp. Reserve the fruit juice separately.
2. Put water and pulp in a saucepan together with any pips and bring it to the boil. Simmer until reduced by half while skimming off any froth.
3. While the pulp is boiling, slice the remaining skin into 3 mm and leave to soak in water.
4. When the pulp disintegrates, carefully press it through a strainer. Add water until the total volume reaches 1000 ml and return to the pot (and throw away the pips and peel).
5. Add the sliced and drained cut peel to the pot and bring to the boil.
6. Simmer until the white part of the cut peel becomes transparent, add half the sugar and cook for 10 minutes, stirring often to prevent it burning.
7. Add the remaining sugar (to taste) and fruit juice then boil until it becomes glossy and thick (you can test it with a small spoonful on a plate to see if it loosely sets). Spoon into sterilised jars while hot.
