Step 4: Cook the Jam
-
Transfer the apricot mixture to a wide, heavy-bottomed pot (a Dutch oven or preserving pan is ideal). The wide surface area helps liquid evaporate quickly.
-
Bring to a boil over medium-high heat, stirring frequently to prevent sticking.
-
Reduce heat to medium and cook, stirring often, for 20-40 minutes, depending on how thick you like your jam.
How to tell when it's done:
-
-
The plate test: Place a small plate in the freezer for a few minutes. Drop a spoonful of jam onto the cold plate. Let it sit for 30 seconds, then push it with your finger. If it wrinkles and holds its shape, it's done.
-
-
Temperature: The jam should reach 220°F (105°C) on a candy thermometer.
-
Visual: It should be thick, glossy, and coat the back of a spoon.
Step 5: Remove Scum (Optional)
As jam cooks, foam may rise to the surface. Skim it off with a spoon for a clearer final product.
Step 6: Jar the Jam
If canning:
-
Ladle hot jam into hot sterilized jars, leaving ¼-inch headspace.
-
Wipe rims clean, place lids, and screw on bands until fingertip-tight.
-
Process in a boiling water bath for 10 minutes (adjust for altitude).
-
Remove jars and let cool undisturbed for 12-24 hours. You should hear the satisfying "pop" as lids seal.
If refrigerating:
-
Let jam cool slightly, then transfer to clean jars.
-
Refrigerate for up to 3 months.
Pro-Tips for Jam Perfection
1. Quality Fruit Matters
The best jam comes from the best fruit. Use ripe, fragrant apricots at the peak of the season. Underripe fruit lacks flavor; overripe fruit may not set properly.
2. Don't Skip the Maceration
That overnight rest isn't optional. It transforms the fruit, creating deeper flavor and better texture.
3. Use a Wide Pot
The wider the surface area, the faster the jam thickens. A narrow pot traps steam and takes forever.
4. Stir Frequently
Apricot jam burns easily. Stir often, especially toward the end.
5. Test Early
Start checking for doneness around 20 minutes. Every batch is different.
6. Let It Rest in the Jar
Jam continues to set as it cools. Don't worry if it seems a little loose when hot—it will firm up.
