I needed some shredded chicken for a recipe today. I poached a few boneless skinless breasts and as soon as I removed them from the pot, I put them in a deep-ish mixing bowl and tried the hand mixer method, using my Kitchenaid 9-speed. Licketysplit it was done and beautifully shredded. I'm assuming the same would work for slow cooked "pulled" pork or tender beef.
It's funny you mentioned this. I watch a Youtuber who has two Frenchie dogs. One has a finicky appetite so she cooks chicken breast for her and adds it to her kibble. She said she bought a hand mixer for exactly what you're talking about--shredding the meat and she said it works great! I wondered about it but now that you've confirmed it I think it's a great tip!
I do this to add eggs, onions and seasonings to ground meat also, doing it by hand my hands would always get so cold from the meat right out of the fridge.
@JeanLouiseFinch ..... THANK YOU for posting this tip. I just did it for first time using chicken breasts also. I used my Kitchen Aid Stand Mixer with the hook (for bread dough?) attachment ....perfect!!!! I imagine hand mixer works good too with regular beaters. Great tip! I'm trying a new recipe for baked chicken sandwiches....if a winner I will post it.
