A short video to explain how to prepare at home and very quickly a mayonnaise. Good tip for children on a SCD or ketogenic diets or for those who need extra calories. There is no issue of digestion if one takes small amounts of it, however, larger amounts would need some metabolic adjustments. I use grape seed oil for this recipe, healthy and not strongly flavoured. You can add various ingredients to the mayonnaise to make it more interesting, but it is very good on its own.
