Shake together:
1/2 cup oil (I used olive, but canola would make it taste more like what you'll find in a restaurant)
1/2 cup red wine vinegar
1 Tbsp sugar
1/2 cup frozen raspberries, thawed and pushed through a fine mesh sieve to remove seeds- this will leave you with 2 or 3 Tbsp of thick 'juice'
dash or two of salt
If you want this to be more creamy, put it in a small bowl and whisk is a Tbsp or two of miracle whip. At first it will seem lumpy, but keep whisking and it will come together nicely.
