Try a slotted roasting pan in the oven. You don’t really have to even turn it.
Grease drops to the bottom and can be poured off or scraped off when done.
I hate to throw away such tasty ... umm ... grease.
I sometimes flaver my dog's dry food with it ... it's a toss-up if he dives for it, or non chalantly nibbles at it.
Ideas, anyone?
