Nope, you weren't nodding off....there's apparently another version of this vid out there on youtube somewhere because the original one I watched has him saying that after his sauce is done, he puts the bowl of it into a plastic bag, puts the vines into the bag next to the bowl, seals it up and sticks it in the fridge... I believe it was overnight... which gives the sauce time to absorb the "odor" of the vines. Seems like an interesting concept to try whcih might give the sauce more tomato flavor. If I am mis-remembering this, I hope someone will jump in with the corrections, but I'm pretty sure that's what he did.
I'm going to try this concept this summer when my tomatoes ripen. I'll report back my findings... and if anyone else has tried this, I would love to hear the outcome!
