This oil-free dressing is incredibly cheap and easy to make, and it’s a fantastic spread for sandwiches, dressing for potato salad or a dip for french fries, if you like potatoes with your potatoes. You can vary it by adding some sriracha for a spicy dip; 1 tbsp chopped fresh parsley and 1 tsp garlic powder for a garlicky version; or even some smoked paprika for a smoky dip. This recipe makes 2 jars’ worth, so scale it down if desired. Because there is no oil, it will separate when stored, so just stir it back together again.
500g potatoes, peeled, boiled and cooled
2 tbsp cider vinegar
2 tsp Dijon mustard
1 1/2 tsp salt
1 tbsp maple syrup
3/4-1 cup water
Blend all ingredients in the blender, adding the water a little at a time until you like the consistency. The dressing will thicken in the fridge.
