There are recipes that fill a jar — and then there are recipes that fill a memory.
Mary’s Rich Plum Sauce is one of those.
First published in my book A High Country Life, this recipe came to me through Joe’s Grandma Mary. The kind of grandmother who didn’t measure much, who bottled in batches big enough to see the family through winter, and who believed a good spicy sauce could rescue nearly any meal.
And she was right.

A Sauce That Carries a Season
Every summer in the high country, there comes a week when the plum trees seem to sigh under their own generosity. Fruit split from the heat, purple skins dusted in bloom, buckets filled faster than you can find jars.
This is when Mary’s Rich Plum Sauce earns its place.
It’s not a delicate drizzle. It’s deep, dark, glossy — sweet but not sugary, rich without being cloying. The kind of sauce that clings properly to a sausage roll, lifts cold meat, transforms a bacon sandwich, and makes a humble pie feel like something special.
It tastes like late summer preserved against a southerly.

From Mary’s Stove to Ours
There’s something reassuring about recipes that travel this way. Not clipped from magazines. Not trend-driven. Just written in looping handwriting on a splattered card, passed down because it worked.
And because it was loved.
When I first included Mary’s Rich Plum Sauce in A High Country Life, it felt important to honour that — the quiet legacy of women who preserved more than fruit. They preserved flavour, thrift, hospitality and the habit of feeding others well.
Why It’s Still a Staple
In our house, this sauce has become the default.
It’s the jar you reach for when the smoko table needs “something extra.” It’s the bottle that appears beside a roast shoulder. It’s what you spoon over sausages when you want to remind everyone that home cooking doesn’t need to be complicated to be good.
And because it’s plum-based, it carries that beautiful balance — natural sweetness with enough tang to keep things lively.
It also makes a rather perfect gift. A jar tied with twine, labelled simply. No fuss. Just flavour.

The Heart of It
What I love most about Mary’s Rich Plum Sauce is that it represents everything I value about high-country cooking:
Seasonal abundance.
Resourcefulness.
Cooking in batches.
Feeding people properly.
Passing recipes down.
It’s not flashy. It doesn’t need to be.
It’s the kind of sauce that sits quietly in the pantry until needed — and then reminds you exactly why Grandma Mary made it every single year.
And why we still do.
If you still have plenty of plums left over. You can always make some fruit leather. My recipe is here for you to try.
Mary’s Rich Red Plum Sauce
Ingredients
- 3 Kg Red fleshed plums
- 1 Onion
- 1 bulb Garlic
- 1 Kg Sugar
- 1.5 Litres Malt vinegar
- 1 tsp Cayenne pepper
- 1 tsp Ground cloves
- 2 tsp Ground ginger
- 2 tsp Ground black pepper
Instructions
- Slice the plums in half and remove the pips.
- Roughly chop the onion and peel the garlic.
- Combine all of the ingredients together in a large pot or jam pan and bring to the boil.
- Once the mixture has reached a boil, reduce the heat and allow the pulp mixture to reduce. Stirring often to avoid the mixture from sticking.
- Once the sauce has reduced use a stick blender to make a smooth sauce.
- Bottle the sauce while it is hot, and use a funnel to pour it into hot sterile bottles. Please be careful and take care not to burn yourself.
- Use a clean cloth to clean the rims before placing the lids on the bottles.
- Leave the bottle to seal overnight. There is nothing more satisfying than hearing the lids go ‘pop’ signifying that they have sealed.
- Once the bottles have cooled and are sealed wash them in hot soapy water to get rid of any sticky spots.
Notes
- During summer you could freeze your fruit in 3 kg bags, so that you can make sauce throughout the year.
- Freeze apricots in halves without the stones.
- I freeze the plums whole, as it’s easy to remove the pips once they have thawed by simply squishing them out.
- Remember the frozen fruit will retain more moisture and you will need to modify the recipe by halving the vinegar measurement.
- If you don’t have a stick blender you could press the sauce through a sieve to get a smooth texture, or place in a food processor.
- Use a jug to pour the sauce into the funnel. You can use the handle to dip down into the pot and the spout makes it easy to feed the sauce into the funnel.
- If you find you have one bottle that hasn’t sealed, place it in the fridge and have it as your first bottle to use.
- If you have more than one bottle that didn’t seal. Boil it up again and repeat the sterilising process. Use a different lid as it may be damaged (especially if you are reusing bottles that you have collected)
