Okay so microwave defrosting can be tricky, for sure! The main thing is using the defrost setting, which is usually like 30-50% power, and doing it in really short intervals, like 30 seconds to a minute, then flipping it and checking it! You want to break up the meat or separate the pieces as soon as you can, that really helps prevent those cooked edges while the middle is still frozen solid! And for sure, cook it immediately after!
Speaking of immediate... my dog, Buster, a Golden Retriever, he's like, always ready to eat immediately! The other day I was making some chicken for him (just plain boiled chicken, no seasoning!) and I was trying to defrost it for his dinner. He was just sitting there, staring at me with those puppy dog eyes, like he was judging my defrosting technique! It's wild how much they pick up on, you know? Anyway, long story short, I almost overdid it because he started whining and I got distracted by his cuteness! LOL! So yeah, stay focused on that meat!
