-
2 egg yolks (room temperature)
-
1 cup liquid (not hot!) bacon fat/grease
-
2 tsp vinegar OR lemon juice. All that is required is acid. Technically acetic acid exists in the human body naturally, could also technically be extracted from insect sources. YMMV, but it opens up a lot of options.
-
1 tsp Dijon mustard, totally optional.
-
Pinch of salt
-
Slightly warm the bacon grease in a saucepan and melt over low heat. Do not let it get too hot! It needs to be relatively room temperature!
-
While the fat is warming, separate your egg yolks from the whites placing the yolks in the bottom of the wide mouth jar. (Save the egg whites for adding back to the mayo to make it softer and easier to spread once refrigerated.)
-
Add your apple cider vinegar, salt and mustard (if using) to the egg yolks.
-
Blitz the yolk mixture with the immersion blender until combined.
-
Once the grease is melted and cooled, slowly pour a small amount of butter into the yolk mixture while blitzing with the immersion blender (about 30 seconds) moving the stick blender up and down and around to ensure ingredients are well combined. You will notice that it immediately begins to emulsify. This is what you want!
-
Continue to run your immersion blender while slowly slowly adding the cooled, melted bacon grease until completely combined. EXPERT TIP: Work your stick blender up and down to incorporate the melted butter and to ensure proper emulsifying.
-
Once all the bacon grease is added, you can choose to add the egg whites (this results in a softer, spreadable mayo when it is refrigerated) continue to blend for another 45-60 seconds moving the stick blender around to insure all ingredients are incorporated.
-
Use warm or seal with the lid and store in the fridge for 3-4 weeks (if it lasts that long!)

Perhaps not saved, but I'd venture the most significant nail in the coffin of the scientific publishing mafia so far, pursued with integrity and honor. The rise of open publishing that followed is very telling, and in my mind directly attributable to Alexandra's work and it's popularity, they know they need to adapt or (probably and) die.
Still need to work on the publish or perish mentality, getting negative results published, and getting corporate propaganda out of the mix, to name a few.
