FOLLOW THESE STEPS
Find and clean a reusable container
If you don’t have a traditional dressing shaker, a mason jar or a peanut butter jar work just as well.
Add 1 tablespoon Dijon mustard
Add 2 teaspoons white wine vinegar
Add 6 teaspoons olive oil
The ratio of oil to vinegar should be 3:1.
Add salt and pepper to taste
A pinch of Kosher salt and of freshly-ground pepper should do the trick.
Shake to combine
Serve or refrigerate.
