Pour ¼ cup of apple cider vinegar into a clean mason jar. This will be the tangy base of your dressing. Then, add 2 tablespoons of canola or vegetable oil to the jar with the vinegar.
Add 2 tablespoons of sugar to balance the vinegar's sharpness. Then, add 1 teaspoon of pink Himalayan salt and ¼ teaspoon of black pepper.
Tighten the jar lid and shake vigorously for about 20 seconds, until the mixture is smooth and well combined. Taste a small spoonful. If it's too sharp, you can add another small spoonful of sugar and mix it well.
Place the jar in the fridge for at least 30 minutes before serving to let the flavors meld. Pour the chilled dressing over chopped iceberg lettuce or your favorite salad mix, and serve it right away.
