Crispy crunchy mega-munchy

crispy-coverI am reliably informed that the taste of a soggy potato crisp – or chip, if you prefer – is identical to that of a crispy one. But the experience falls far short of enjoyable. A crisp needs to be, well, crisp. If it isn’t, it actually tastes bad. That’s not quite so true of things like fried or oven-roasted potato chips; they still taste pretty good when they’re not quite so crispy, but they’re even better when they are crispy, and that goes for a whole lot of other cooked crispy things too. Which is why it is such a shame that by the time you get to the bottom of a plateful of fries or nachos, they’re soggy. Not to mention thin-crust pizza in a box. Ken Albala, a food historian at the University of the Pacific in Stockton California, happens to be an accomplished ceramicist, so he invented a plate that helps keep foods crispy. And that prompted an episode on crispy crunchiness.

The argument that the appeal of crispiness is innate – that is was selected for by evolution – is not that far-fetched. John S. Allen, a research scientist at the Dornsife Cognitive Neuroscience Imaging Center and the Brain and Creativity Institute at the University of Southern California, writes that “[c]rispy foods are certainly not the only type of food that humans find appealing, and of course some people do not even like them. But the pervasive appeal of crispy is clearly something that emerges out of our multiple, interacting histories”.

There’s more to it than just the texture or the sound of the food breaking in our heads, but there does seem to be something to Allen’s ideas. What, though, is the difference between crisp and crispy? My sister says that, for her, carrots are crisp, while fried noodles are crispy, and that’s an importance distinction, for her. I’m not so sure. I think one could possibly separate out the texture from the flavour, at least experimentally, and see whether there really is a difference. Of course all sorts of sensations affect the experience of eating something, but whatever the truth of the matter, I’d just as soon not have to eat soggy crisps.

    Can’t help but feel that a preference for crunchiness in veg and fruit is linked to a preference for freshness. If you have an old carrot or cauliflower it really is a bit limp and unappealling.

    Re chips and newspaper, however, i have to disagree. Crisp chips are not favoured in the North of England where they should be soggy, slightly disintegrating each other, with a few crunchy bits and a liberal dose of malt vinegar.

      You may be right about freshness, but I wonder whether there were any not-so-fresh veggies around way back during all this evolutionary selection that John S. Allen thinks was going on. As for chips, I agree. Some people don’t understand fully the delightful diversity of the various members of the chip tribe.

  2. Lost in this discussion is the components of the ‘crispy coating’ and the water or steam level of the coated contents. Batters where the starch has been given a chance to swell and gelatinize versus breadcrumb or raw starch coatings that are toasted by cooking will affect the initial crispiness as well as how long a coating stays crispy. Also the moisture content of food can affect the results.

    Potatoes are fried twice for chips or fries. Once to cook the potato, brown the surface, and seal the exterior, and again at a hotter temperature to crisp the exterior. Tofu coated with cornstarch will stay crisp for eons.

    Ken’s bowl does the same thing as the cooling rack used in restaurants for deep-fried foods. It allows excess oil to drain but not collect under the recently fried foods.

      Thanks for your comments Peter. Of course you’re correct, there’s a whole lot more to crispiness. I’d love to go into more detail, especially about techniques like ice-cold batter.
