Fractal cabbage


Back in the days when fractals where the most fashionable thing, I had heard of fractal cabbages, and seen pictures of them. However, they are typically not available in French or American stores, so I didn’t see a real one until noticing that they are very common in Swiss supermarkets. Here’s a picture of one, but I should say that pictures do not quite convey the actual feel of seeing and handling this vegetable (not to mention eating it — and it is indeed quite tasty). The diameter (of horizontal cross-sections) of the specimen displayed here is between 10 and 15 centimeters, and the height is slightly larger.

  2. I agree, they look beautiful and taste really good. I first had them in Grenoble.

  4. Thanks for the reference! (I have to admit I didn’t do any measurement of the structure of the vegetable…) Amusingly, there was none in the store where I usually buy them this morning…

  5. I would like to know the Hausdorff dimension of this cabbage.

  6. I think in culinary circles they go by the name “Romanesque Broccoli”. Very pleasing on the eye, the mind, and the tongue!
