Food with a Fibonacci Spiral (+ Romanesco Recipe)

Food with a Fibonacci Spiral (+ Romanesco Recipe)It’s probably the math fan in me, but as soon as I saw romanesco available at our local market, I had to buy it and try it. Yes, it’s a cruciferous vegetable. Yes, I’m sure it’s very healthy (lots of vitamins C and K, carotenoids, and, of course, fiber). But my decision to purchase was mostly from an aesthetic perspective.

Spirals occur in many places in nature: snail shells, some flowers, pinecones, DNA, pineapples, and even our galaxy.

But until the other day, I had not seen them occur in a vegetable I was planning to cook for dinner.

While I didn’t pull out a ruler and start measuring to see if its spirals truly fit a Fibonacci sequence, I did take advantage of the opportunity to explain the idea of the golden spiral (a logarithmic sequence that mathematically explains the increasing width of a particular type of spiral) to my 6-year-old. He acknowledged the spirals on the romanesco, mentioned a few facts he learned from a kid’s book we have about spirals (Joyce Sidman’s Swirl by Swirl), and said he thought the vegetable looked a bit like legos.

Not every meal in our house touches on higher mathematics, but I was tickled that this one did.

The romanesco tasted quite good, sort of a milder, nuttier cauliflower taste with a bit of a smoother texture. We ate the better part of two large heads in one sitting.

I prepared the romanesco as follows:

 

Steamed Romanesco Recipe

Romanesco
Olive oil
Balsamic vinegar
Salt and pepper

Steam the romanesco for 15 minutes or less, depending on how al dente you like your vegetables.  I use a steamer basket like THIS.

Place the steamed romanesco in a bowl slightly bigger than the amount of vegetable you have. Add olive oil, balsamic vinegar, salt, and pepper to taste; I apply them generously.

Mix well, and serve.
