Combine egg yolks and mustard in a bowl. Very slowly, add a small amount of the canola oil to the mixture in the bowl. Rapidly whisk the canola oil into the yolk/mustard mixture until the oil is completely incorporated. Once you have the emulsion (it should look like mayonnaise, and not be separating), slowly add the remaining canola oil into the bowl, whisking rapidly.
If you got the emulsion right off the bat, before adding more oil, you should now have a bowl of your very own homemade mayonnaise. Add salt to taste and store in a mason jar. This mayonnaise will keep for up to 5 days.
