Common Questions
What does Christmas jam taste like?
Think bright and tangy like cranberry sauce, but sweeter and more spreadable, with orange and warm spice in the background. It is festive without being perfume-y.
Do I have to use pectin?
You can cook it longer without pectin, but set can be less predictable and the fruit flavor can dull a bit from the extra simmer time. This recipe uses a small amount of pectin for a more reliable gel and fresher flavor.
Can I use frozen fruit?
Yes. Frozen cranberries and frozen strawberries both work. No need to thaw, just expect a couple extra minutes to reach a boil.
My jam is too runny. What now?
First, chill it fully. Jam firms up as it cools. If it is still loose, return it to a saucepan and bring it back to a full rolling boil that cannot be stirred down. Boil for 1 minute, then re-test once cooled.
If you want to add more pectin, follow the directions for the specific pectin you are using. Low-sugar and no-sugar pectins are not all interchangeable, and the “how to add more” step can vary by brand.
My jam is too thick. Can I fix it?
Yep. Warm it gently and stir in a splash of orange juice or water, 1 tablespoon at a time, until it loosens.
Is this the same as cranberry jam?
Close cousin. Cranberry jam is usually cranberry-forward only. Christmas jam adds strawberries plus orange and spices for a rounder, more holiday-style flavor.
Can I water-bath can this recipe?
This post includes fridge and freezer directions as the default. For water-bath canning, use a tested canning recipe (such as one from Ball or the National Center for Home Food Preservation) that matches your ingredients, pectin type, and jar size, and follow that recipe’s processing time and altitude adjustments.
