What does spit up taste like?

So I had Jehan standing on my stomach yesterday after he woke up from a nap and he spit up. Not just regular spit up but the projectile kind. I very narrowly avoided finding out what regurgitated milk, rice, and carrot tastes like a couple of hours into digestion. Luckily my mouth was closed but it got all over my face and the front of my shirt, and for lovely imagery, it ran around to the back of my neck and got in my hair and all over the sheets to boot. Lovely.
