Step 1: The Formula!
The formula is:
3 parts oil + 1 part something acidic + seasonings/flavor additions = salad dressing
Not so bad, right?
For example, if you wanted one cup of salad dressing, you'd need 3/4 cup and 1/4 cup.
Step 2: Ingredients and Equipment
We'll start with the a pretty basic recipe. For this, you'll need:
vegetable oil or extra-virgin olive oil*
white wine vinegar
salt and pepper
*After experimentation, I can say that I prefer the olive oil version. However, vegetable oil is certainly cheaper and will work in a pinch.
Step 3: Measuring and Mixing
You put the lid on first, right? Then you're done! Taste it to be sure that it doesn't need more seasoning. Then, serve it on your favorite salad.
If you don't need much dressing, try 3 tablespoons oil and 1 tablespoon vinegar. Or 6 tablespoons oil and 2 tablespoons vinegar. You get the idea.
In the photos attached here, the larger jar contains 1 cup of a vegetable oil and white wine vinegar mixture. The smaller jar contains 1/4 cup of an olive oil and white wine vinegar mixture.
