Patty Saveurs

Make the mayo:

Lay a wet cloth under your bowl so as to stabilize it

Into the bowl, add cold mustard and egg yolk, whisk until well incorporated, as soon as incorporated, drizzle a little bit of oil and whisk in to start the mayo, then drizzle a thin stream of oil, continuing whisking

Add salt and pepper to taste, make a well spiced mayo

At this point, you can either keep on adding oil and whisking until you are satisfied with the quantity, or you may opt for the light mayo version and add the Greek yogurt, incorporate the yogurt with a spatula or spoon

Taste and adjust seasoning if necessary

Optional: Add your choice of herbs or a mix, add the juice of 1 lemon
