Yvonne made an oil and vinegar dressing using an oil to vinegar ratio of 3 tablespoons to 2 tablespoons. She tasted the dressing and decided it was too oily. Which oil to vinegar ratio could Yvonne use to make a less oily dressing?

To make a less oily dressing, Yvonne could use a higher vinegar to oil ratio. For example, she could try a ratio of 2 tablespoons of oil to 3 tablespoons of vinegar. This would result in a more acidic and less oily dressing.
