My Costco sells avocado oil mayo - no need to make my own. The local Publix has "avocado oil mayo" but if you look at the ingredients it's the classic soybean oil, canola oil - with a little smidge of avocado oil. The Chosen Foods brand at Costco is 100% avocado oil.

And my favorite thing at Costco? Their langostino tails! Some of those with melted butter and I can feel like I'm having my adored lobster.
