What foods do you always have in the house? You know the ones that your cooking and eating are built around?

Mayonnaise is not one of those foods in my house, at best I bought it because I needed it for potato salad, or because I knew someone was coming who would want it. I had no objections to the jarred stuff because I didn’t really eat it or care.

But recently, I had a craving for coleslaw and as luck would have it, all the ingredients except mayonnaise. So I googled it and came up with this link. Two minutes, all ingredients I have in the house, I had made mayonnaise. Go me.

I’ve made it a couple times since and this is the combination that I like best.

• 1 whole egg
• 1 tablespoon lemon juice (from 1/2 a lemon)
• 1 tablespoon wholegrain mustard
• 1 teaspoon sea salt
• 120ml sunflower oil
• 120ml light olive oil

It couldn’t be easier, add all the ingredients to a tall container that is just wider than the base of your stick blender (this is the one that mine came with!)

Put blender in container, blend until it all emulsifies and looks like mayonnaise.(If you realise halfway through that your stick blender as died, then what I did was transfer everything to the small bowl of my magimix and pray. That worked!)I much prefer it to the stuff you buy in bottles and I will try it in potato salad when summer comes around.
