Ingredients
3/4 cup olive oil (light olive oil works best)
2 T Dijon mustard
1 T lemon juice
1/4 cup chickpea brine (yep the stuff you usually tip down the sink from your can of chickpeas!)
1/2 tsp salt
what to do
Put all the ingredients in a narrow blender (or tall narrow container if using a stick blender). If your blender has a wide jug it may not work, and you may need a stick blender or NutriBullet type blender, my vitamix works fine.
Blend starting slowly, then increasing speed slightly, until it is thick and creamy, usually about a minute. Store in a glass jar in the fridge for a week. It will thicken slightly more after refrigeration.
This recipe can be temperamental to work with, and even with exact measured ingredients can sometimes end up with two completely different textured mayos! I suspect maybe the temperature and exact measurements might play a part. If it’s not thickening up, adding a scant 1/4 cup wholegrain mustard turns it into a really delicious tangy mayo, add then blend until thick. Often now I will add wholegrain mustard from the start (and omit the Dijon mustard) because I like the flavour.
