Spiced Blueberry and Onion Sauce

spiced blueberry and onion sauce 002

A truly, delicious, savoury fruit sauce.

Anglo-Saxon cooking used to have a lot more savoury fruit sauces like this, 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.

Recipe notes

  • 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. You can also use 1 1/2 teaspoons ground ginger instead.
  • To use alternative sweeteners such as honey, Splenda, agave, etc, contact Pomona directly to inquire about amounts they would suggest and how to incorporate. It’s almost certainly possible.
