Yes, david, into the pasta. Bit of a binder. I caramelized the onion then added the garlic and spinach. I killed the heat when the spinach wilted and let it sit while the pasta finished.
I saved about 1/2 cup of the pasta cooking water when I drained the pasta (I always do this). I returned the heat under the spinach to very low, then stirred in a couple teaspoons of glaze and several teaspoons of juices from the foil. Then I dumped in the pasta along with a splash of the cooking water, stirred, and covered for a couple minutes to allow the pasta to absorb some liquid and flavor. A couple tablespoons of freshly grated parm, stir to melt; done.
Ray-- Yes, I'd say 50-50, probably 2 T of each, then 2 t of maple syrup and 1 t of butter. Since this mix was already thick enough, I simply nuked the bowl for several seconds to melt the butter.
On these ribs I played up the sour. In the rub: a little sugar, more onion and garlic, extra-hot NM chile, sage and lemon thyme, cumin, a little ginger, cracked black pepper, a fair amount of sumac and a good dose of amchoor. The bit of sugar balances the fruity sour of the sumac and amchoor.
Pomegranate molasses has its fruity sourness, of course; the bit of maple syrup balances that. The veneer that gets painted on is enough for color and shine and flavor, but is applied thin enough to not mar the texture of the bark and meat.
