The giant yorkshire pudding bowls made in flan trays are awesome - the bottom end up saturated in gravy and delicious, and it's really fun serving the whole meal inside them. But they do take up a lot of oven space. I'm usually cooking for two, which is fine, as two of the 6" trays will sit happily next to each other. If you're cooking for more this might not work.
I grabbed a 6-bowl tray for hosting friends at Christmas (£12 on Amazon) and it worked really well too! (Not the best picture fo them.)
If you do buy one of those trays be sure to get one with a raised rim around the edge. When you pour in the batter you can then fill them to the brim and not worry about the displaced hot oil getting everywhere.
