A smooth, bright orange jam made from peeled, pureed oranges and simmered with a bundle of warm winter spices. Just oranges, lemon juice, sugar, cinnamon, clove, and star anise, with a soft, spreadable set and no added pectin. The perfect seasonal jam for toast, baking, or a winter cheese board.

Instructions
Peel the oranges, removing the zest and as much of the white pith as possible. Go back over each one with a paring knife to remove every last bit of pith, since leftover pith makes the jam bitter. Save the peels for candied orange peel if you like.
Puree the peeled oranges until smooth, using an immersion blender right in the pot or a countertop blender in batches.
Measure the puree. You are aiming for 4 cups. If you have more or less, adjust the sugar to keep a ratio of 3 parts sugar to 4 parts puree by volume.
Tie the cinnamon stick, cloves, and star anise into a spice bag. Combine the puree, lemon juice, and sugar in a wide, heavy-bottomed pot and add the spice bag. Bring to a boil over medium-high heat, stirring frequently so the puree does not scorch.
Cook until the jam reaches gel stage at 220 degrees F on an instant-read thermometer. Because puree holds more water than trimmed segments, this can take a little longer, so trust the thermometer over the clock. Remove and discard the spice bag.
Ladle the hot jam into clean, hot half-pint jars, leaving 1/4 inch headspace. Wipe the rims, apply lids and bands, and tighten to fingertip tight.
For immediate use, store in the refrigerator for a few weeks or the freezer for up to 6 months. To can, process in a boiling water bath for 10 minutes, adjusting for altitude. Let the jars rest 5 minutes in the canner, then cool undisturbed for 12 to 24 hours and check the seals before storing.
Notes
Fruit amount: About 2 1/2 pounds of whole oranges, weighed before peeling, purees down to roughly 4 cups. Measure the puree and hold the 3 to 4 sugar-to-fruit ratio, adjusting the sugar if your yield is higher or lower.Soft set: This jam has a soft, spreadable set with a smooth texture. A softer set is normal for jams made without added pectin, and it firms up further in the jar overnight.The spice bag: Cinnamon, clove, and star anise give this jam its cozy winter character. Keep them in a spice bag so they flavor the jam as it cooks, then lift the whole bundle out before jarring. Go easy on the cloves, since they are strong.Plain version: For a pure, unspiced orange jam that lets the citrus stand on its own, simply leave the spice bag out.Do not skip the lemon juice: It balances the sweetness and helps the jam set properly. Without it, the jam is cloyingly sweet.Do not reduce the sugar: The 3 parts sugar to 4 parts fruit ratio is what allows this jam to set without added pectin. For a genuinely lower-sugar jam, use Pomona's Pectin and follow their directions separately.Orange varieties: Navel oranges are the simplest to work with and reliably sweet. Cara Cara oranges are milder and sweeter, and blood oranges give a deeper color and a more complex flavor, though they hold more juice and take longer to cook down. Choose a seedless variety or remove the seeds before pureeing.Testing for set: Gel point is 220 degrees F at sea level, dropping about 1 degree per 500 feet of elevation, so at 1,000 feet it is about 218 degrees F.No thermometer? Use the cold plate test: drop a teaspoon of hot jam onto a frozen plate, and if it wrinkles when pushed, it is set.Yield and storage: Makes about 3 to 4 half-pint jars, depending on the juiciness of the oranges. Sealed jars keep 12 to 18 months in a cool, dark place. Once opened, refrigerate and use within 3 to 4 weeks.Altitude adjustment: Process for 10 minutes at elevations up to 6,000 feet, or 15 minutes above 6,000 feet.
