Many years ago, I bought the Italian bible: Essentials of Classic Italian Cooking by Marcella Hazan. Frankly, I don’t use it as much as I should, but it’s my go-to for sauces in particular.

I’ve made Hazan’s alfredo sauce approximately a zillion times. I’m an alfredo fan, and it’s a quick sauce to make, as well. A 10-minute gourmet dinner.

But I have never in my life made that sauce as well as my 9yo did Sunday night.

The recipe itself is simple:

1 c. heavy cream
2 T. butter

Melt together over low heat until slightly thickened. Add:

2/3 c. grated Parmesan Reggiano

Stir til melted. Season with salt, pepper, a pinch of freshly grated nutmeg.

Boom. That’s it. And yet I’ve gotten this sauce wrong more often than not. After I tasted the 9yo’s version, I immediately knew why.

I love, love, love my Microplane graters. I have one for zest, nutmeg and Parmesan sorts of things, and a larger one for softer cheese. Ever since I’ve owned them, I haven’t used any other kind of grater. I used to use a Zyliss grater for Parmesan all the time. It produces a thicker grate–so the finished product is denser than it is with the Microplane.

[Yes, we're about to dive off the culinary cliff, in which I demand recipes with weights and measures.]

I had the 9yo use the Zyliss to grate her cheese, because there’s no way to slice off half your arm, like there is with the Microplane. End result? I’m guessing her sauce had 2-3 times as much Parmesan as mine usually does. And the result was to-die-for.

You could certainly achieve the same result with the Microplane, just by using lots more than 2/3 c., or by packing it down [how much??], but the best thing would be to know how much cheese we’re actually talking about. Saying 1 c. of something solid really tells you nothing. Liquids are more predictable when you’re measuring volume. This is why your cereal is measured by “weight” and not by “volume.” 12 oz. of cereal = 12 oz. of cereal, but 12 oz. of the exact same kind of cereal might be 2 c. or 3 c., depending on how it packs into the measuring cup on any given day.

So, next time we make alfredo, we’ll use the Zyliss and weigh the result. Then we’ll know exactly what we’re dealing with in the future.
