This recipe for home-canned Spiced Blueberry and Onion Sauce makes a truly, delicious, savoury fruit sauce.
European cooking used to have a lot more savoury fruit sauces like this (pre-1500s), so it’s a real blast from the past. A splodge of it really does go great on a dinner plate, and may just give cranberry sauce a bit of a long-overdue run for its money next Christmas.
The first year, you’ll make one tentative batch: the second year, you’ll be doubling and tripling the batch, for presents.
You can make this with sugar, or honey, or you can make it sugar-free.
If you wish to adjust batch size, do the math first on paper.

What is the shelf life of home canned goods?
- You can dice the onion in the food processor with the pulse button, if you like.
- For the ginger, you can just use 2 tablespoons of minced ginger from a tube or jar. You can also use 1 ½ teaspoons ground ginger instead.
- Instead of the salt, you can use a non-bitter, non-clouding salt sub. We have found Herbamare Sodium-Free performs well in that regard.
- You can reduce the sugar, or use the same volume amount of granulated Splenda®, or 125 ml honey (½ cup / 4 oz), or 1 teaspoon of liquid stevia. For stevia, we’d recommend Better Stevia liquid stevia . For further sweetener choices (agave etc) contact Pomona directly.
