How to align custom MDF cabinet doors?

[salbo]

Hey!
I've built my own cabinet doors out of MDF for a piece of furniture. Glued a frame on them and leaned them against a wall. Not smart. Now they're like bananas.

Is there any smart way to straighten them?
Wet them?
Or do I just have to start building new ones?

Right now they've been lying with 40kg on each for about 1-2 weeks without result.

Have a fantastic day!

Did you glue the frame on the edge or on the flat side?

If you glued on the flat side, you can throw away the doors, you'll never get them straight.

Thanks for the expertise!
On the flat side.
Maybe it's not a good idea to make the same ones in the same material then?
Thinking about going to buy a pine countertop and make new ones.

Bought 18mm pine boards and 8mm trim as panels. Is it just as likely that this will warp? What should I consider to avoid that?
Skip the glue?
Paint before I attach the panels?
Place something flat and heavy on the entire door when I glue (if I glue).
Or is everything fine?

I have no idea about this stuff.

Strips you place along the grain direction can be glued, the ones across it you might only want to nail so the wood can move.
