This time of year brings Seville oranges to the markets in Paris. For the past few years, I kept wondering why they were so hard to find since it’s perhaps my favorite of all jams and jellies to make, and eat. But lately, they’ve been everywhere.  And I found myself busy making a lot of marmalade, which was easier since I came up with a brand-new, revolutionary technique which I couldn’t wait to share.

Since Seville oranges are rife with seeds, which makes slicing them difficult since you have to keep moving the seeds around with your slippery fingers, while trying to cut the oranges, then finding more, and fishing around deeper inside to extract more, plucking them out, etc… Each Seville orange has perhaps twenty to thirty inside.

So I thought, what if I was to squeeze the juice and seeds out first, strain them, then pour the juice back in? The seeds are precious commodities in jam-making, and get saved and used since they’re so high in pectin.

They’re wrapped in a sack and cooked with the marmalade giving the marmalade gets a suave, jellied texture. And this simple method, featured in my book Ready for Dessert, makes the whole process much easier.

You might be interested to know that Seville Orange Marmalade was created because of an error. Apparently, an Englishwoman in 1700, the wife of a grocer, was stuck with some sour oranges that were bought cheaply from a boat that was carrying them from Seville.

Since there was a storm, they wanted to get rid of their stock or oranges quickly, so the grocer bought them. But they were inedibly sour so his wife decided to try making jam from them, and viola!…Seville Orange Marmalade was invented.

In my book, I advise letting the cooked oranges and the seeds rest overnight. That's an optional step. If you want to go ahead and finish the marmalade the same day you start it, you can.

• 6 Seville oranges, (see Note)
• 1 navel orange
• 10 cups (2.5L) water
• pinch of salt
• 8 cups (1.6 kg) sugar
• 1 tablespoon Scotch, (optional)

• Wash oranges and wipe them dry. Cut each Seville orange in half, crosswise around the equator. Set a non-reactive mesh strainer over a bowl and squeeze the orange halves to remove the seeds, assisting with your fingers to remove any stubborn ones tucked deep within.

• Tie the seeds up in cheesecloth or muslin very securely.

• Cut each rind into 3 pieces and use a sharp chef’s knife to cut the rinds into slices or cubes as thin as possible. Each piece shouldn’t be too large (no more than a centimeter, or 1/3-inch in length.) Cut the navel orange into similar-sized pieces.

• In a large (10-12 quart/liter) stockpot, add the orange slices, seed pouch, water, and salt, as well as the juice from the Seville oranges from step #1. Bring to a boil, then reduce to a simmer, and cook until the peels are translucent, about 20 to 30 minutes. (At this point, sometimes I’ll remove it from the heat after cooking them and let the mixture stand overnight, to help the seeds release any additional pectin. But it's not imperative.)

• Stir the sugar into the mixture and bring the mixture to a full boil again, then reduce heat to a gentle boil. Stir occasionally while cooking to make sure it does not burn on the bottom. Midway during cooking, remove the seed pouch and discard.

• Continue cooking until it has reached the jelling point, about 218ºF degrees (103ºC), if using a candy thermometer. I cook this slightly less than other jams and marmalades because the high amount of pectin helps the marmalade set up more stiffly. To test the marmalade, turn off the heat and put a small amount on a plate that has been chilled in the freezer and briefly return it to the freezer. Check it in a few minutes; it should be slightly jelled and will wrinkle just a bit when you slide your finger through it. If not, continue to cook until it is.

• Remove from heat, then stir in the Scotch (if using), and ladle the mixture into clean jars. Sometimes I bury a piece of vanilla bean in each jar. (Which is a great way to recycle previously-used or dried-out vanilla beans.)

I don’t process my jams, since I store them in the refrigerator. But if you wish to preserve them by canning, you can read more about the process here.

Note: Sour or Seville oranges are called in French oranges amères and are available mid-winter in many other countries around the world as well.
