• If you don’t have apple cider vinegar, you can use red wine vinegar or white wine vinegar

Can You Freeze Keto Thousand Island Dressing?

You sure can, but with just a small word of caution. Though this low carb salad dressing will freeze for up to a couple of month, because it contains mayonnaise, the texture will slightly change when thawed. To reincorporate all the ingredients, just give it a good whisk and enjoy!

What’s the difference between Thousand Island and Big Mac sauce?
