Fermented Mayonnaise



I love mayonnaise and this creamy home-made variety tastes in my opinion far superior to shop bought ones.  If you use free-range (preferably organic) eggs you also get a completely different colour mayonnaise and grass-foraging chickens have healthier Omega 3 containing eggs. I’m sure you’ve noticed the difference in yolk colours but when you crack an egg from a free range egg, you get a vibrant nearly orange coloured yolk, compare this to a barn coloured egg yolk and you’ll get an insipid pale yellow mayonnaise.

Having used olive oil in the past, I prefer avocado oil, it doesn’t have the overpowering flavour coming through the mayonnaise.  Avocado oil is also high in Vitamin E which is reputed for its health benefits to the skin.  Avocado oil has been used in studies for healing wounds and found particularly useful for those who suffer with psoriasis.

I used to be nervous of making mayonnaise thinking it would curdle or take ages to make but moving towards a whole-food life, I decided to make this healthier swap and I’ve never looked back. This takes me 3 minutes maximum from start to finish and then you can ferment the mayonnaise in the most natural way possible using whey that you can extract from your kefir.
