(expeller-pressed, melted and cooled - could also use ghee)
Throw the first 4 ingredients in a blender and turn on. With motor running SLOWLY add the oils, until incorporated.
Last, add 2-3 tsp of lacto-fermented sauerkraut juice. If you want to take this a step further and actually ferment then leave covered on a counter overnight - then place in fridge. Otherwise, if it weirds you out, put in fridge right away. The sauerkraut juice will make it last longer regardless.
Use mayo for egg salad (or other salad sandwiches) on Paleo Bread or a yummy Aioli dip for sweet potato fries.
