I'm not trying to argue it.
I left my original comment as a fun anecdote in response to another fun anecdote. In reality, I think it's probably not a good idea to cook food in hot asphalt but didn't feel that really needed to be said, so didn't say it. (How many people are even going to have the opportunity to try that?) Now I am feeling like perhaps it does need to be said and cringing in anticipation of people hating on me for saying it and thereby raining on their party.
I looked up the info rather than go "citation needed." My children are grown. They have already survived whatever mistakes I made in raising them and life has changed, so some of what I did worked just fine at the time but is no longer a good idea.
I provided citations and accurate information to the best of my ability and as neutrally as I knew how in the interest of promoting food safety for people currently or in the future in need of actually feeding babies.
