Baking – What are these white spots in the bread dough

bakingbreaddessertveganyeast

I'm making hot cross buns following this recipe: https://domesticgothess.com/blog/2020/03/09/vegan-hot-cross-buns/

About an hour into the first rise, I'm seeing these alarmingly mold-like dots in the dough. I didn't see these when I was kneading it.

white spots on bread dough

The only things I might've done abnormally for this recipe were:

  1. My soy milk might've been a touch too hot when I added the yeast. I was afraid it would kill the yeast, but it looks like the dough has risen normally. Not sure if that has something to do with the appearance of these spots.
  2. For the soy milk, I made it using cooked soybeans blended up with water. It was done in a high speed blender and the soy milk appeared quite smooth, but could these be unblended soybean chunks?
  3. I used kosher salt. Perhaps the salt was not fully dissolved by the time I let it rise.

Are there any other possibilities for what these spots could be?

It's impossible to say what it is - but I am quite sure what it isn't. I have never seen or heard of a pathogen (mold or otherwise) which is able to build visible colonies during such a short time at room temperature, especially in the presence of yeast. And your yeast was not dead - the dough rising proves it.

This is almost sure some ingredient not being mixed well. There are a few alternative explanations such as you covering the bowl with a nonpermeable lid and having enough condensation to drop onto the dough surface, or maybe (and we are getting into really weird/rare territory here) the vegan substitutes acting in unusual ways and managing to clump somehow. I would bake and eat - it is one of the exceptions where I can't connect this unusual photo to the "when in doubt, throw it out" rule.
