You could make a gravy or stock with them or toss them.

What do I do with the giblets

No Flour needed. I’ve been doing beer can chicken for a long time and it’s excellent meal that’s easy on the pocket. Never has disappointed and I’ve done it several ways. I always have white or yellow rice on the side with ours.

My go too:
Pat Dry & lightly cover with olive as a binder. Season heavily on a tray laying flat, do both sides – cover everything! You cannot over season this if you’re using the right seasoning. Then grab a sturdy bake safe pan of any sort (5lb that you handle while hot comfortably) . Drink 1/5 of the beer and set it the center of the cooking tray. Grab the chicken, trying not lose any seasoning while handling when possible but some are a tight fit, & place it on the beer can as snug fit as possible to
Make it stand stable. Usually have to get the legs spread out right to stand it up good. Once stood up how you prefer – continue to season the top and places you might have lost season do to handling. Coat that bad boy! I use at least half a tube of seasoning per chicken. Set to the oven to 400 to preheat. Once ready place chicken in oven and immediately turn down to 350-325. Cook 20 minutes per pound at this temp range. Example: 4lb hen would be 1hr 20min minimum. Done Internal temp is 165 (make sure not to test touching a bone but meat only). Remove from oven & let sit on the can for 10 more minutes while the juices redistribute to doneness. Take two forks and hold chicken up – have a friend take an oven mit and pull the boiling beer can out while you are leveraging the chicken with the two forks. Throw the beer in the sink or pour out. ENJOY!

Seasoning – Weber Beer Can Chicken
Beer – (any normal sized can / any beer) flavored beers will leave hints on flavor example blueberry beer.

4lb whole chicken

Your recipe calls for flour but doesn’t say what to do with it.

It might not give it a ginger-ale flavor but it will steam it just like a beer would
