Lays vs Pringles
Composition Pringles and Lay's are actually two different categories of snack food. While Lay's are a conventional chip made of sliced potatoes deep-fried in oil, Pringles are actually potato crisps composed of potato flakes, fillers and other products. In other words, a home chef could never create a Pringles chip at home, but could easily make a Lay's type of chip. Because of this, the Lay's chip will always have more variability in the realms of appearance, flavor and texture, whereas Pringles are pretty much the same from canister to canister.
The Difference In Appearance Since Pringles and Lay's are so different in substance; they share practically no common ground as far as appearance is concerned. Lay's chips are simply sliced potatoes dropped in oil and salted (or seasoned, depending on the variety). Therefore, they twist, turn, brown and caramelize in the hot grease. No chip looks the same as another. Pringles, on the other hand, are far from random. According to Proctor and Gamble's Pringles FAQ, "Dried potatoes and other ingredients are mixed into a dough, which is rolled flat and individually discs are cut and placed in a specially shaped carrier which and then taken through the fryer. They are then seasoned, stacked and packed. The whole process is fully automated." These are the chips you want if randomness isn't desired.
Flavor Differences Between the
Chips
Pringles are the chip to eat if
you want a uniform snacking
experience with no surprises.
Since the chips come from a
uniform batch of dough, they
all taste the same. The texture
is a bit mealy; it's obvious that
something else is mixed in
with the potato, but it's
pleasant to the palate. They're
also salted and flavored on the
top side only, making it simple
to change the concentration of
spices during the eating
experience.
Lay's, meanwhile, are quite
random. They're a great deal
more greasy than Pringles, and
have a toasty taste. There are
chips with bubbles, sour green
spots and burnt sections. No
chip tastes like the others; the
most uniform chip in the Lay's
line is Ruffles, but even that
brand still shows variation.
However, its obvious that one
is eating a potato, not an
amalgam of such.
Varieties These days, both brands boast an extensive line of flavors and cooking methods to entice a wider variety of customers. Both Pringles and Lay's manufacture low and no-fat potato chips. Lay's now produces its own line of crisps called Stax that have a recipe similar to Pringles. Both lines have ridged chips that are marketed towards those who like chips and dip. The Lay's spread of cooking methods wins; they offer original, kettle-cooked and baked varieties. Pringles, meanwhile, has a huge list of flavors that Lay's doesn't, with some cross-over. A consumer looking for a range of tastes due to cooking methods will probably like Lay's best, while one seeking interesting flavors would be best served with Pringles.
