Some times the best things in life truly are simple, after one day of being criticized for eating commercial salad dressing I picked up the bottle and read it. There was tons of things in there that were just fillers, so I started making my own. Find yourself a jar and the following,
1/2 cup fresh or thawed raspberries (mash them)
60ml water
1 tablespoon sugar (or alternative sweetener, it takes the edge off the vinegar)
60ml vinegar (chefs choice, I use apple cider)
1 tablespoon oil
Mix, mash and stir everything together. Pour into your bottle and store in the fridge. Shake before each use.
