Mike, don't know if it will help you with the cooking but I can tell you what I think I know from 25 years of growing my own. As Celia and Christina have said, what you've called "stems" in the garlic world go by "scapes". The flowers you've exposed by peeling the one flower head are called "bulbils". I'm sure the flower head itself has an official name too, but I don't know what that is. All are produced by what called "hard-necked" garlic varieties, those that have a woody stem (the base of the scape once mature) in the middle of the head. The soft-necked garlic you normally encounter in US grocery stores reproduce only from the underground part in the way Christina described; hard-necked kinds also can do it via bulbil.
So much for the terminology. The flower heads on your scapes look much larger than on the varieties I've grown. Mine have typically been no smaller than a pencil with the scape maybe half that size. I'm also guessing from the photo that yours are pretty mature, more so than you'd really want. Like Christina and for the same reason, I cut the scapes off as soon as I notice them. At that stage, they're quite tender and you have a number of options: they can be sauteed as you did, snipped and used raw as mildly garlicky chives equivalent, stir-fried, or simply steamed as a green vegetable - slightly garlicky with a texture a little like asparagus. In that state I don't pay any special attention to the flower heads, which are also quite mild. Yours look a little far gone for that; I'd be inclined use as you would regular garlic. If you run into garlic scapes in future farmers' markets, you might look for more tender examples - I think you'd find them more versatile and better all-around.
Once mine throw scapes (yet to happen here), I'll post a photo if I can re-figure out how to do that. Some varieties do some pretty interesting things, like twist into a 270 degree loop, so that the top of the scape (with flower head) is parallel to the ground!
