This is the real answer right here!

Not just partners but really anyone it's easy if you establish who is the head chef and who is the sous-chef(s).

I'm happy to cook with as many sous-chefs as we can cram into the kitchen. Heck I'll put someone on a grill outside if I get too many. An extra two sous-chefs? Sounds like we're about to have two extra side dishes. Maybe a pie. Now the dishes are washed before we're done. Now they're dried and put away! I can find more tasks! Floors swept, counters wiped, I can find tasks for a small contingent of sous-chefs! Mad with power.

And same in reverse, there's something so hypnotic about just being the sous-chef. YES CHEF. Cut the veggies smaller YES CHEF. Just go with the flow. Ahhh
