It seems really close to another recipe favorite of ours, Walla Walla Sweets.

Here’s our take on the recipe; our additions are in [square brackets]:

• one large [sweet] onion per person [if the onions are really big, maybe one onion per two people]
• double cream [heavy whipping cream in the states]
• grated Parmesan [cheese]
• [also grated swiss or gruyere cheese, if you like]

1) Peel the onions and boil in a pan of water for about 25 minutes until tender.
2) Remove and drain then slice in half.
3) Place in an oven-proof dish cut side down and cover with cream and as much parmesan [and other cheeses] as you like.
4) Bake for about 30 minutes [at 350 degrees] until golden and bubbling.
5) [If the cheese hasn't browned to your liking, turn on the broiler for 5 or so minutes (watch it, since it will go from white to brown to burnt within 30 seconds!)]

It’s a really yummy and simple dish that uses ingredients that aren’t strange, and if you ignore the fact that you’re dousing it in cream and cheese, is probably not all that horrendously bad for you. Really. }:>
