The California Cook: From dregs to delicious

Here in California we love to brag about our abundance of wonderful seasonal ingredients and how that makes good food easy. That’s more or less true, but I have to confess that I’ve also always had a sneaking admiration for those cooks who can whip up something from nothing.

Sure, it’s wonderful to be able to just pick up a sack of Ojai Pixie mandarins and a box of medjool dates and call it dessert. But you’ve really got to admire someone who can take a couple of wilted zucchinis, a sprouting onion and some canned tomatoes and turn that into something delicious — the real-life equivalent of the proverbial stone soup.

I’ve got my own version, and, in fact, it does start with something hard as a rock. In a battered plastic bag in the deepest recesses of my refrigerator, I’ve got a hidden stash of gold: rinds from used chunks of Parmigiano-Reggiano. Whenever my wife finds them, she pulls them out and asks disbelievingly: “You’re saving these?” And probably 98% of people would have the same reaction.

But those rock-hard rinds are flavor bombs, packed with umami. Simmer them in a pot of beans, in a soup, even in a tomato sauce, and you probably won’t actually taste Parmesan, but you’ll certainly taste the difference.

Those rinds can also take on a more starring role. One of the trending preparations in restaurants right now is Parmesan broth — at its essence, simmered Parmesan rinds. It makes a wonderful light sauce with a subtle nutty, buttery flavor that serves as a complementary backdrop to all kinds of spring dishes.

There’s a little more to it than simply boiling rinds, of course. I start mine with a combination of chicken broth and water — half and half is a good starting point. Most canned stocks and broths are better appreciated for the flavors they imply rather than the ones they actually possess. And in this case, even a good homemade stock would be too strong by itself. You want to taste the cheese, not the chicken.

With that I simmer some sliced garlic and a handful of whatever herb trimmings I have from prepping the other ingredients. Again, this is an Italian-style broth, meant to be subtle.

It’s not quite something from nothing, but it comes pretty close.
