any way of making 'butter' with soy milk?

[journey]

Is there any way of making homemade 'butter' with soy milk? As in when we were kids, they had us make butter in a churn with dairy milk (heavy whipping cream) so we could understand where butter comes from.

A historic reenactment group I work with is going to demonstrate butter making, and I can't change that. But if it were possible to make the soy milk gel into butter by churning it, I might be able to talk them into using soy as a healthy substitute, but the process would look realistic for the demonstration.

But I'm not too sure soy milk will turn into an Earth Balance type thing if you churn it?

I think a butter like compond will be impossible with standard kitchen equipment but maybe give a demonstration of how to make tofu (bean curd) from soy milk, instead? You'll also need a coagulant like calcium sulfate, too. I think tofu would be more analogous to how you make cheese from cow's milk because both have a curdling stage and then a form filling/ hardening stage.

You could argue that butter has absolutly zero nutritional value to a human, all it does is harden the arteries, whereas tofu is a good form of healthy, complete protein with all the amino acids. Good luck.
