So, we ran out of mayo today and I decided I would make some, as I had everything I needed.
Pretty much, crack the egg in the container, whisk it, add the lemon juice, keep whisking and then in a steady drizzle, add the oil while still whisking. Yes, I was tired of whisking by the time I was done, but really probably only took me like 1 minute total, perhaps 1-1/2 minutes total to make. I added a dash of garlic powder and a dash of sea salt. Tastes just like the store bought, only a little yellower, perhaps because the egg I used was from our chickens, so the yolk is way more orange (due to them free ranging and it is much fresher than store bought).
