The theory makes sense to me - the little lacto bacilli are quite good at preserving milk (yogurt etc), and veggies (sauerkraut etc), so giving them a chance to colonize the mayo doesn't give me pause.
well, you're in good company. I recently bought Nourishing Traditions but I'm still in transition. Still trying to wean the family off canola and other vegetable oils. My sister tells me that the ginger carrots are bulletproof, so I might do that next. I've had several batches of sour kraut fail. Also, I'm experimenting with kimchi.
Come to think of it, everything is probably colonized with the exception of my in-use canning jars. So maybe it's not a big deal. But I think I'll pass on the semi-fermented mayo. The usual suspects for milk souring are bacteria that evolved (or were designed, to be religiously correct) to have their metabolism revved up for lactose (galactose-glucose). While other things can digest this particular sugar, the laco-bacilli have a heat start. And their acidic poo makes it hard for other stuff to grow. OK so far. But mayo basically is oil with egg yoke, which is mainly oil. I'm not seeing the point of adding culture that eats milk...
Anyhow, it's not a big deal. Do as you please. I'm just thinking out loud. I'm always surprised how much I learn from others on the forum.
