Spice Mix 1 tsp. Dried Dill 1 tsp. Dried Cilantro 1 tsp. Dried Chervil 1 tsp. Garlic powder 1 tsp. Onion powder 1 tsp. Salt 1/4 tsp. Dry Mustard 1/4 tsp. Ground Black Pepper Mix & Store in a spice Jar. Add 1 tbl. Spice blend to 1/2 c. Buttermilk + 1/2 c. Mayo or Sour Cream. Stir until smooth. Store in refrigerator. Notes- 1) You can modify the spice blend to your taste. 2) It’s probably best to make the dressing in small quantities. Unlike what you buy at the grocery store, it lacks preservatives, so it does not have the same shelf life.
