Lady Ross Relish is a Canadian relish with many tall tales behind its name. While there actually was a Lady Ross, who lived in Montreal for a time, it’s not certain that there’s any actual link between this recipe and her.
It’s also sometimes called “Lady Rose Relish.”
This is a mustardy cauliflower relish, thickened with flour. While it generally isn’t considered safe to thicken home-canned products with the flour, the exception is if the recipe has been lab-tested for safety by industry technicians, as this one has been. So enjoy!
Note: this can have a potent mustard bite, especially if your mustard powder is strong and fresh — though it does mellow in time.

How to water bath process.
How to steam can.
When water-bath canning or steam canning, you must adjust the processing time for your altitude (follow the table above.)
For salt substitute, a non-bitter, non-clouding one such as Herbamare Sodium-Free was used.
For stevia, Better Stevia liquid stevia was the stevia used.

Australia and New Zealand vinegar strength special notes.
- Use a food processor if you’ve got one to finely chop all the veg.
- Peel the cauliflower head, wash it. Cut it into smallish florets; don’t leave in large pieces. Place florets a few at a time into the bowl of a food processor and whiz them just until it is broken down to the size of rice or wheat grains. Repeat until you’ve processed all the cauliflower.
- 2 medium apples, 10 to 12 oz in weight combined.
- Trim off both ends of cucumbers; this is to get rid of an enzyme that could make your relish go soft.
- Yes, that really is 60 g of mustard seed and 75 g (3/4 cup) of mustard powder, those are not typos.
- For a finer relish, you can use 3 cups finely chopped instead of 4 cups (coarsely) chopped (both will be the same weight, about 500 g / 1 lb)
- If the relish is turning out “thick” for your taste, you can add more vinegar (5% or higher.) Sometimes we add up to 250 ml / 1 cup / 8 oz more.
- For a more golden brown colour, add some Kitchen Bouquet a 1/2 teaspoon at a time until desired golden colour is reached.
