can't cook ribs

[Entervixen]

So I uninstalled and reinstalled The Sims 2. Now my maxed out cooking sims are unable to cook ribs. I have a grill, and two of them have maxed out cooking, but they are both unable to grill ribs. I have only minimal CC, and the only mod I have is the nude patch, but I've downloaded that a million times and I have never had a problem with it. As far as EPs go I have Double Deluxe (base game+nightlife+celebration stuff) Open for Business, Freetime, and Teen Style Stuff. Anyone got any clues on how I can fix this?

Make sure the fridge is fully stocked. I couldn't get it once either. So i just filled the fridge and I could do ribs. Apparently Ribs use alot "food numbers" Much like how the lobster uses alot of "food content numbers"
Tell me if that works.
