For most of my life I bought salad dressing in bottles at the grocery store. I was always amazed by seemingly exotic salad dressings that could be found in restaurants, until I learned how to make my own. Homemade salad dressings can be so much more than simple oil and vinegar; almost any fruit or spice can be the basis for a salad dressing, and you can control how much sugar you want to use.
One of my favorite "exotic" dressings has always been avocado (or avocado ranch) dressing. Here's my gluten-free and dairy-free version:
1 medium avocado – the riper the better
¼ cup light olive oil
1 tbsp lime juice
2 tbsp water
¼ tsp salt
Puree the avocado in a food processor or blender until smooth. Add the other ingredients and continue to puree until well blended.
If you're not sure what to do with that avocado that is about to go bad, make some salad dressing!
