The Food Lab: Better Home Cooking Through Science

(Nandana) #1

to those within a certain quality level, the best knife for you
is the one that you are most comfortable using. Anyone who
tells you different is selling something. Probably knives.
When buying a knife, there are three main characteristics
to consider: material, shape, and ergonomics.
The material a knife is made out of determines several
factors, including how sharp it can be, how long it retains its
edge, how easy it is to resharpen once it’s dull, and how it
reacts with acidic foods. In general, you’ve got three
options: carbon steel, ceramic, or stainless steel.



  • Carbon steel is a softer metal that is easy to sharpen, and
    it can be ground down into an extraordinarily sharp edge.
    Its disadvantages are that it dulls relatively quickly,
    requiring you to resharpen it every few weeks or so to
    maintain a good cutting edge; it can rust if not cared for
    properly; and it will discolor if it comes into prolonged
    contact with acidic fruits or vegetables. You have to
    carefully clean, dry, and oil it after each use to preserve its
    luster. Carbon steel is the material of choice for knife
    geeks who take great pleasure in the process of
    sharpening a blade down to a cut-through-anything-
    without-even-noticing edge. Just like a dog, it requires
    plenty of hard work to keep it well disciplined and
    healthy, but it’ll reward you with a lifetime of loyal,
    faithful service. And unlike a dog, your knife will never
    pee on the carpet. That’s a good thing.

  • Ceramic blades are generally a poor choice. It’s true that
    they can be ground to a razor-sharp edge, and that that
    edge doesn’t dull even with prolonged use, but their major
