* I like to use extra virgin olive oil for this recipe, but olive oil will add some flavor. I personally love that taste, but you can use a mild-tasting oil like sunflower or grapeseed. Olive oil will also solidify a bit in the fridge, so your mayo consistency might change a little, but that’s very easy to fix. Just give it a good whip with a spoon to get it all nice and creamy again.
