The whole point to making homemade mayonnaise is to escape the unhealthy canola oil. Canola oil is GMO and always befouled and rancid. Bad PUFAS cause heart disease and inflammation.
Here is a much better recipe.
20 second Mayonnaise
You need a hand blender for this.
The world’s laziest mayonnaise recipe:
Prep time: 20 Seconds
Total time: 20 Seconds
Yield: 1 cup
Crack a pastured egg into your immersion blender container. Don’t even bother to separate the yolk. Add two teaspoons of dijon mustard, a tablespoon of lemon juice, and a pinch of salt. Pour in 200ml of good quality olive oil. Put hand blender to the very bottom of the container and blend until it thickens into mayonnaise.
You don’t need the immersion blender container. Use a large glass or small bowl. Big strong jelly jar water glasses work perfectly.
You need healthy eggs - cheap ones should,not he eaten raw.
