I started the baby backs for 2 hours around 250 275. Then foiled them with apple juice for 1.5 hours l, took off foil and back on for about 25 min. I was planning on doing another 30 min but I went ahead and tried the bend test. Well there wasn't much bend before they just fell apart. They were moist, tender and tasted great but I'm just wondering if over cooking or to much foil time caused them to break apart. This is just my 2nd time with ribs so still trying to learn.
