I had some very yummy "overnight porridge" at a conference and I didn't get a good photo but I really want to recreate it at home. It had a texture similar to overnight oats and was cold, so I'm pretty sure it was an overnight soak, but it has several grains. Oats, maybe quinoa or something that looked similar, and at least one other grain I didn't recognize. What other grains soak well overnight and would go either nicely? Thanks!
