Weigh your oil into your mayonnaise container and set aside.
Insert butterfly and add vinegar, yolk, mustard, honey, salt and pepper to mixer bowl. Mix for 1 min/37°C or 100°F/speed 4/MC on.
Set mixer to 3 min/speed 4 and very slowly start drizzling oil into bowl. Take the full 3 min to do so. At this point you can taste and adjust honey, salt and pepper as desired.
Store in an airtight container in the fridge for up to 5 days.
Tip: To fix a split mayonnaise, pour out the mix into a container, clean mixer bowl and start mayonnaise mix again using the failed mix as the oil.
