Without deviation progress is not possible
Weird thing happened last time making toum, it thickened without adding any egg-whites
Similar type of immersion blender,garlic,oil,salt,lemon juice,container. Moon effect? sea level as opposed to higher elevation? blitz it all together expecting it to be thin and then adding the egg,but upon pulling out,thick and creamy.Screw those people that post recipes on the net saying to slowly drizzle oil alternatively with lemon juice which should endure 30-45 minutes when it can be done in under 5 minutes,add another 60 seconds if requiring those egg whites.
You're basically make aioli, which is yolks only. If you're hyper religious about the texture, it may make a difference, but I wouldn't sweat it myself. I like to use roasted garlic in aoili /toum and round out the flavor with a bit of dry mustard with a dry spice (coriander) or a fresh herb from time to time. Italian parsley is nice.
