Get your stick blender assembled.
Crack and separate out your two egg yolks and place into a narrow jug
Crack and separate out your two egg yolks and place into a narrow jug with the fresh lime juice and sea salt
Stick blend these for 30 seconds
Then add each of the fats in two stages - ie, 15ml / 1/2Oz at a time, stick blending on high for 20 seconds at a time before adding your next little drizzle
Then pop in your smoked chipotle and sweetener of choice and do a final blend for 5 seconds. You're done. A delicious thick mayonnaise for spreading onto bread, serving with mets or falafels or dipping crudité into. Enjoy!
Option for a creamy dressing variation: Add 15ml / 1/2Oz more of each of the oils, 2 more pinches of salt and the juice of a whole lime to the above for a further blend of 20 seconds, if you want a longer, thinner mayo-style salad dressing.
