We don't use much mayonnaise in our house but occasionally we want some for salads, sandwiches and sashimi tuna. Lots of mayonnaise recipes are tedious and difficult but if you have an immersion blender, it's a really quick process. I'll put the recipe after the video.
Step 1: Ingredients
1 cup of vegetable oil
1 whole large egg
1 tablespoon vinegar
1/2 teaspoon fresh ground black pepper
1/2 teaspoon mustard powder
1/2 teaspoon kosher salt
Some folks use blends of oils like olive oil, canola oil and the like. I just use store brand vegetable oil and it works out great.
I don't know if this recipe would work with a pasteurized egg. I'm not that worried about salmonella but I know some folks are.
I've tried different kinds of vinegar and I find that ordinary apple cider vinegar works best and I get the best texture at the end.
