I've been doing it for years. Once upon a time, I had a girlfriend who was trained in a culinary school. I don't use vinegar, just the squeeze of fresh lemon. I use olive oil. At the end, I add crushed garlic. Only fresh ingredients of course. No garlic powder or garlic from a jar. Only fresh lemons from my brother in law's Meyer Lemon tree. Only fresh eggs from the farmers market. Locally, I can get fresh, cold pressed, olive oil. Garlic grows in my back yard. Lemon skin can be zested. Egg whites are used for omelettes, frosting, or steaming. Even the egg shells are used in a stock recipe, then into a compost bin in the garden. Nothing is wasted. Living in California, we can buy fresh & local, and our climate allows us to grow quite a bit. Even downtown, at the little apartment, I have food growing on the balcony. 5 gallon buckets from Home Depot are growing potatoes and tomatoes. A fish tank becomes a makeshift aquaponic system with all the green onion I want, all year round.
