Ay, constant struggle nga yan. So, here's the deal: get an instant-read thermometer. Seriously, it's a game-changer. No more guessing if it's still pink chicken or dry roast.
Just stick it in the thickest part, avoid bones. Chicken 165°F (74°C), beef depends on your preference, you know? Like, 130°F (54°C) for rare, super juicy. Also, let it rest after cooking! Like, important. Don't cut it right away, give it 5-10 mins for juices to redistribute. Trust me, it helps a lot. Happy cooking! :)
