Where do I find reliable information on plant based substitutes?

I'm trying to teach myself how to cook and I don't know enough to be able to tell when information on the internet is accurate. I have a box of pancake mix and I'd like to replace the cow milk with some kind of plant milk. The vibe of cooking sites is vaguely spammy, and I can't tell if they are misinformation or not. Cooking is a high effort activity for me so I need to know if something is mostly going to work before I attempt it.

Where do you go to find information that is accurate and comprehensive?
