This is the romanesco broccoli I bought in my local farm shop today.  I'd never eaten one before and I needed an extra vegetable for dinner tonight.  And OK, I really wanted to have a closer look at the buds, which are made up of logarithmic spirals.  In theory I could have photographed it at almost any magnification and achieved the same result, as each bud is (almost) a natural fractal.  According to Wikipedia (whose appeal for donations I just answered), the vivid colour is chartreuse, somewhere between green and yellow, named after the French liqueurs I tasted once upon a time, and decided that once was enough.  I'd recommend romanesco though, roasted with a little avocado oil, lemon juice, sea salt and black pepper.  What you choose to drink with it is up to you.
