Make a Nerdy Dinner : Fractal Soup
This guy came home with us last week. We like to bring one of these vegetables home maybe once a month. It’s an interesting looking thing, isn’t it? We’ve never seen anything like it in the United States.

The vegetable is officially called a romanesco. Sometimes it’s romanesco broccoli. Other times it’s romanesco cauliflower. We didn’t know any of this before. All we knew was that this vegetable had the most amazing mathematical structure. The florets spiral into peaks, creating nature’s own perfect fractal. They’re the perfect food for people of math and science.

But how are you supposed to cook them?
After weeks and weeks of seeing Martin leaning over this vegetable while I gather potatoes or eggs, I told him to grab one. ”What’ll we do with it?” Martin asked. He wasn’t even looking at me. He was still gazing at all the mathematical glory stuck between red cabbages and ginger.
“I don’t know,” I said, shrugging. ”Maybe soup?”
Soup is always the answer. And as it turns out, romanesco makes an amazing soup! I treat it just like broccoli soup, which is just by touch and feel. Soup is such a flexible food. I rarely turn to a recipe. Soup can be the perfect food to try experimenting with and inventing your own combinations.

As it turns out, romanesco soup is delicious! It’s also really fun. But you can’t call it romanesco soup. Oh no! I had to look up the word “romanesco” just to write this post. To lure in the non-vegetable, scientific folks, this recipe must be called: fractal soup.
Here’s my simple recipe for Fractal Soup:
1. Sauté some chopped onions, then add garlic
2. Add chopped fractals/romanesco
3. Sometimes add a little bullion or herbs (optional)
3. Pour in hot water (mine’s from the hot pot – so German of me!) so the vegetables are 2/3 submerged
4. Add salt and pepper
5. Cook around 5-8 minutes until almost tender – don’t let them get mushy
6. Add cream and quark (quark is optional)
7. Pour in the blender and give it several quick pulses
8. Serve with grated cheese and croutons (which are just cut up stale bread coated in olive oil and toasted or broiled)
Now I’m curious. What’s the weirdest thing you’ve picked up at the grocery store lately? Any pickled pigs feet out there? Or a label you could not understand only to find out you brought home something way, way wrong? And while we’re at it – any math junkies out there? Know someone who’d love to chow down on a little fractal soup before the summer heat hits us?
Want to get cooking with some of our funnest recipes? They’re all on one handy-dandy recipes page right here. From homemade graham crackers to different European cookies we’ve featured on Making This Home, it’s all there. Yum!

This will sound funny to you: A few weeks ago, I bought sweet potatoes for the first time! And just like you, I made soup of them. Some years ago, romanesco was one of the very few vegetables our math-loving son would eat. So I bought it quite often though it is rather expensive.

I love broccoli soup, but I prefer not to add cream, cheese, or even herbs and just let the lovely broccoli flavor speak for itself. It’s easier, cheaper, and healthier! All you have to do is cook the broccoli, drain (reserving the cooking water), puree in a blender, and add the cooking water until it is your desired thickness. Salt & pepper to taste are all you need to really bring out the broccoli’s greatness. I don’t know if the fractal’s flavor is strong enough/nice enough for that method, but maybe give it a try sometime! If I see one at the Turkish Market today, I’m planning on it :)

Very interesting…I’ve never seen one before. One of my favorite soups is cauliflower soup; it’s very white and creamy (from pureed potatoes, not cream). I would probably make soup out of this guy, too. I love trying all sorts of new vegetables. When we go to the farmer’s market in spring and summer, I try to pick out something new to try. Last summer I was hooked on microgreens and sprouts. I tried growing some sprouts myself, but couldn’t get it right so I gave up. I should try again.

Wow! this the strangest vegetable I’ve seen! What other fun foods will I find in German? Can’t wait to move there and find out!

Heh, romanesco is definitely available in the US; I’ve seen it at farmer’s markets before. No, it’s not as well known as cauliflower, but definitely not just something for this side of the pond!

We’ve gotten romanesco in our CSA box (http://www.eatwell.com), and I agree, it’s a gorgeous vegetable… but then I think all vegetables are beautiful! :) Glad to hear you made a good soup with it!

Soup sounds good. I dont have anything this exotic, wonder if I could raise this in my garden? I’ll check it out.

They sell those in our supermarket – they call them broccoflower. I think it is a cross between broccoli and cauliflower.

I made soup for dinner this evening by using up two pork ribs and most of the vegetables we had in the refrigerator. My DH, (the chef) thought it was great! Glad you thought of it! LOL!
My husband works in an upscale grocery, in the produce department, and he said they have had Romanesco for years. They get it from California. He describes it to customers as a cross between a cauliflower and broccoli; it helps to relate NEW foods to KNOWN foods. LOL!

My favorite freaky food is Buddha’s hand.

It’s a citrus zest. No juicy fruit, inside. It looks just like an gnarled, old, arthric hand. It’s so COOL! LOL! I used it for seasoning fish. It can be used to make marmalade. Or tossed into a salad. Or made into a tea. Or just used for the scent.

Something STRANGE happened on that wikipedia link.
Let’s see if it will copy and paste correctly THIS time:

Romanesco reminds me of seashells. It also looks like a cross between broccoli and cauliflower. I’m assuming the flavor is close to cauliflower.

mmm, fractal soup!

Well… fooey! I can’t type, either! LOL!
REDO: …It looks just like an gnarled, old, **ARTHRITIC** hand. It’s so COOL!

I can not believe it. When I was in Germany I pointed out this very vegetable and said it looked like a fractal. My friend – a writer – looked at me like I was a lunatic. She had no idea what a fractal was and I was feeling super nerdy UNTIL RIGHT NOW. : )
