Great videos Rick.
Can I ask the change in how you rolled and portion the spinalis dorsi was that purely done because of a change of purpose?
Also think i will just tie them up like you, meat glue is probably hard to come by here. Also some prelim reading says people with gluten issues may have problems with it and i have a few friends which have quite high intolerances to gluten.
I'm thinking for this dinner party i might give this a go amd may debate on sous viding the prime rib or roasting ala Mucho for the christmas lunch. Still plenty of time to experiment with that.
