Learn how to make your own mayonnaise. What a great cooking skill to have. How to make mayonnaise is part of the Have Butter will Travel 'How to' series.
Ensure your stick blender will fit into the glass jar opening. If not make the mayo in a jug or other narrow tall container and transfer it to the jar for storage
Add the egg, vinegar, mustard and salt to the glass jar, then top with oil
Place the stick blender in the jar so it is touching the bottom and turn it on to high
Leave it blending for 5-10 seconds and you will see the mayo start coming together
Slowly raise the blender to make sure all the oil is incorporated and then lift it up to the top to mix in any oil there (take care not splatter the mayo everywhere, just take it slowly)
Once it is all combined you are done! Store in the fridge
