Installing blocking between the rafters (actually I think you mean "ceiling joists") is a good solution.
I'm not sure what your pot rack looks like, but if you're going up into the attic, you might be able to lay a 2x6 across the top of the joists and use a piece of all-thread (long rod that's threaded end to end, available at any hardware store (Home Depot, Lowe's, TSC, etc.)) to go up through the drywall, through the blown-in insulation, through your 2x6, and through a washer and nut. That would be easier to install and even stronger than your blocking which relies on the shear strength of screws. However, I do think that your blocking would be strong enough for a pot rack.
