Trim the fat on a Costco butt?

P_HopP_Hop Posts: 5
Looking to pick up a package of Boston Butts from Costco to cook for Thanksgiving.  I have used the ones from Costco before and they turned out great but they seem to have a large amount of fat on the top that did not create as much bark as I would have thought. I ended up cutting a good part of the top off when it was complete.  Do I cut out some of the fat prior to cooking or leave well enough alone an trim as needed at the end?

  • I would rather trim before and enjoy the bark/not waste rub on the fat. There is plenty of fat inside the butt to keep things moist.

  • Remove fat for better bark. Its the rub and smoke that cause the bark, not melts and washes the rub (bark) away with it.
  • I trim before the cook, and yes there seems to be more fat of late on the Costco butts. Trimmed a good 4 to 5 oz of fat off the last 6# butt, the dog was very happy, she likes it nuked for about 2 minutes in 8 oz of tap water, served over Kirkland kibble. Darn near licked the bottom out of her dish.

    Fill a small tin pan, like a loaf pan with "Old Glory" turnip greens. Place fat on top. Leave uncovered to retain smokey flavor and then cover.

    I used to leave the Costco butts as I go them and realized I was throwing away a lot of the flavorful bark. The last 4 I cooked, I trimmed as much of the fat as I could, pretty much all of it on the cap, rubbed it and did the usual low and slow with much better results bark wise, the pork was still plenty moist as well. I don't cook them without trimming the fat anymore.

  • I trim as well and find if I rub the butt down with yellow mustard and then work my rub in. The bark results are amazing!
