This is a Japanese tweak on old-fashioned marmalade using the little-known yuzu. These wonderfully fragrant citrus fruits are just starting to catch on outside Japan, and since the best part of the fruit is its rind, marmalade is a perfect way to preserve and enjoy it. You can expect the familiar marmalade texture and hint of bitterness, but with the powerful citrusy punch of yuzu.

Put the seeds into a cheesecloth sachet or teabag packet; this packet will be used to extract pectin from the seeds during cooking. Take about a quarter of the reserved membrane and mince it for more pectin; discard the remainder.
Use a spoon to scrape the white pith off of the inside of the rinds and discard it. The more of the pith you remove the less bitter the final product will be, but don’t go overboard and scrape away the flavorful skin layer.
Put the remaining rinds in a small saucepan and add enough water to cover them. Bring to a boil and boil for 1-2 minutes, then pour off the water. Repeat this one or two more times—add more cold water to cover, boil, discard the water. After the second or third boil, cover the peels with cold water and let soak for 1-3 hours. Both of these processes reduce the bitterness.
Cut the peels into very thin slices. In the pan mix the sliced peels, the juice, the reserved chopped membrane, and the sugar. If there isn’t much juice add a quarter cup to half cup (50-100cc) of water. Stir together, add the packet of seeds, and heat over medium. Once it begins to bubble, reduce heat to low.
Simmer over low heat for about 15 minutes, skimming off any scum that floats to the top. After 15 minutes, remove and discard the seed packet. Simmer for another 15 minutes or so; once it has begun to thicken a little, remove from heat. It will thicken after it cools, so do not over-thicken while cooking.
Yuzu is an Asian citrus that isn’t generally eaten straight; instead, the juice and very fragrant peel is used in cooking, as in this recipe. The yellow fruit is about the size and shape of an orange, with a unique, powerful citrus flavor. Although extremely cold-tolerant, they have yet to catch on in the United States or elsewhere, so the plant and fruit are both quite difficult to find; the fresh fruit is just starting to make its way into some well-stocked supermarkets. Try a Japanese specialty grocer if you don’t have luck elsewhere.
