How to keep a meatball round? After seeing this question I started to think more about my meatballs and wonder how can I keep them round? 

I have always been under the impression that you should first brown the outside and then cook them through.  Problem is during the browning in the frying pan I end up with flat sides.

What can I do?  Help my meatballs!
I saw a recommendation on 30 Minute Meals to place each one in a muffin tin (they were sized so they stuck out the top), and then bake them.  You'd have to find the right sized tray for your size of meatballs, though.

I'm guessing you'd also want a large tray underneath, though, or you risk dripping grease inside the oven.

... you could probably also just put 'em on a sheet tray and bake 'em, and you'd only get one flat side, rather than from each time you turned them in the pan.
