hi ive had issues on the outcome of smoking my ribs...ive basically only have done spare and hotel-cut(which i have no clue what the difference is in cut) other than the flap being cut off...i have to cut the slabs in half in order to fit in my masterbuilt electric smoker...the narrower ends(not so thick) are coming out fantastic but the thicker ends are tough....you can tell there not right because of how tougher they are and the meat is grayish color....im even keeping them in a little longer than usual....i do the 3-2-1 method and use apple juice in the part "2" method...can the thicker end be trimmed down or no...help!!!
