It broke somewhere along the way, not sure what the specific cause was though. I may have kept it on the heat for too long, or added the cream a bit too quickly. I was super disappointed, there is little more disheartening in the kitchen than a recipe gone wrong.
Luckily, I still had the zucchini parm, noodles, and spaghetti sauce in the cupboard. Thank goodness, meal salvaged.
