What format for new ssd for MacBook 2012

I've already installed opencore on my MacBook 2012 back in January with no problems but the harddrive has failed so need to reinstall on a blank sdd.

I have the usb for booting opencore but what do I format the blank ssd drive I'll be putting back into the MacBook?

Cheers
