I've seen photos of Romanesco broccoli online, identifiable by the fractal arrangement of its florets.
Fractals are basically self-similar patterns, with the same characteristics at various levels of scale. Romanesco has at least 3 levels of self-similarity, with groupings of smaller florets on the larger florets.
I finally saw this visually interesting vegetable in the supermarket for the first time, so I knew I had to get it! I wanted to see how it tasted.
Below are some photos I took, with both a regular & a macro lens. The last photo is the result - the steamed Romanesco broccoli for dinner, with baked chicken and waffle fries w/ Sriracha.
It was definitely more bland than regular broccoli, but I always spice up my veggies anyway. I like the texture of the Romanesco much better. It didn't have the little leaflets on regular broccoli that get stuck in your teeth.
Anyway, I will definitely get it again for other dishes. Besides, I love to look at the fascinating fractal form, so it's worth getting for that alone!
