Thousand Island Relish

Thousand Island Dressing has lived on, but Thousand Island Relish has largely been lost to history.

You can revive this old relish in your own kitchen, though.

We’re not certain of the exact culinary historical origins of this recipe, or just how old it is, but it has been kicking around Canadian kitchens along the St Lawrence River in handwritten form for several generations now. And it almost certainly was kicking around in relatives’ kitchens on the American side of the river, too. This rendition of the recipe has been tested to modern USDA canning safety standards for heat penetration, density, pH, seal, etc, by Canadian Living. (See: Canadian Living as a reputable source of lab-tested recipes.)

This recipe makes a lot; you may wish to cut the recipe in half unless you have a lot of friends who’d love a jar for summer cookouts.

Recipe notes

• Trim off both ends of cucumbers; this is to get rid of an enzyme that could make your relish go soft.
• To seed the cucumber, cut it lengthwise and drag the tip of a spoon along the centre.
• To chop the cucumber, you can cut the peeled, seeded into chunks, pop in a food processor and use the pulse button.
• For the flour, use plain flour or all-purpose (i.e. don’t use self-rising.) Feel free to cut back a bit on the flour, by up to half, even, for a less thick relish.
• You can use all one colour of a pepper; the two different colours are just for look.
• The purpose of the soaking here is to infuse the vegetable with flavour.
• Instead if the sugar, you could use the same volume amount of Splenda® OR 3 teaspoons liquid stevia.
