The Food Lab: Better Home Cooking Through Science

A   perfect French  fry should  have    a   crisp   crust   that    breaks
instead of bending.


  • Perfect Fry Factor #1: The exterior must be very crisp
    but not tough. In order to achieve such crispness, the
    surface structure of a fry must be riddled with
    microbubbles. It’s these tiny crisp bubbles that increase
    the surface area of the fry, making it extra crunchy.
    Ideally, this layer should only be as thick as it needs to be
    to add crispness. Any thicker, and you start running into
    leathery or tough territory.

  • Perfect Fry Factor #2: The interior must be intact and
    fluffy and have a strong potato flavor. Fries with a pasty,
    mealy, or gummy interior or, even worse, the dreaded
    state known as “hollow-fry” (when the interior is missing
    entirely) are an automatic fail.

  • Perfect Fry Factor #3: The fry must be an even light
    golden blond. Fries that are too dark or are spotty have an
    off-putting burnt flavor. Light golden but perfectly crisp is
    how I want my fries to be.

  • Perfect Fry Factor #4: The fry must stay crisp and
    tasty for at least as long as it takes you to eat a full
    serving. Fries that comes straight out of the fryer are
    almost always perfectly crisp. The true test of a great fry is
    whether or not it is still crisp and edible a few minutes
    later, after it’s been sitting on your plate. The bendy fry
    pictured above fails that test.


First, a few decisions. For potato variety, russet is what you
want. Its high starch content means that it’ll fry up crisper
