If you like your spices gold-colored and expensive, find some fresh Crocus sativus flowers and grab ‘em by the…disproportionately large female reproductive organ. Small hands might work best, though it might turn your skin orange. Saffron is probably from the Middle East. If that bothers you, you may want to ban it from your spice shelves, however ill that bodes for the quality of your cabinet. After all, there is a stigma against that sort of thing.
The most expensive oversized reproductive organ in the world

You may know that saffron is the most expensive spice in the world. A Spanish farmer sold his crop of high quality saffron this year for four euros per gram, which is a ninth of today’s price of gold (36 euros per gram). Saffron is expensive because its production requires a huge amount of labor and land. Saffron production is labor- and land-intensive because saffron is a botanically unique food item that defies mechanical harvest and accounts for a miniscule proportion of the plant that bears it. The saffron threads sold as spice are the dried stigmas of the flowers of the saffron crocus (Crocus sativus, family Iridaceae). Recall that the stigma is the part of the flower’s female reproductive organs that catches pollen. Pollen travels from the stigma through the style into the flower’s ovary (collectively, the stigma, style, and ovary comprise the pistil). Continue reading

Is there anything good about green bean casserole? Not much beyond its association with Thanksgiving, so Katherine will be brief and just keep you company in the kitchen in case you are stuck assembling said casserole.
Since this year is the International Year of Pulses, we have been focusing on legumes, whether they count as pulses or not. Green beans do not count as pulses, but only because they are eaten as tender and fresh immature whole fruits. The very same species (Phaseolus vulgaris), when allowed to mature, could yield black beans, white beans, kidney beans, or pinto beans depending on their variety – dry seeds that are perfectly good examples of pulses.
This Thanksgiving week we are going to welcome green beans into the fold and give them a special place. It’s too bad that Thanksgiving so often presents them out of the can, overcooked, with funky flavors, and buried in a casserole. Even Wikipedia promotes this peculiar tradition : “A dish with green beans popular throughout the United States, particularly at Thanksgiving, is green bean casserole, which consists of green beans, cream of mushroom soup, and French fried onions.”
And once again, international observers ask themselves what on earth are Americans thinking? That cannot be good for them. But in the American spirit of inclusivity we invite green beans of all sorts to our tables and try to learn something from them. So if you are preparing green beans this week, take heart, take up your knives, and take a closer look.

In 2016, the International Year of Pulses, we’ll be writing a lot about pulses (dried beans and peas), and we’ll also tackle the huge and diverse legume family more broadly. This weekend Katherine kicks things off with February’s Botany Lab of the Month: beans and chickpeas for your Superbowl bean dip and hummus.
The species name of Cicer arietinum means “ram’s head.”
Beans are a bit like football: a boring and homogeneous mass of protein, unless you know where to look and what to look for. In this lab, we’ll make the smashing of beans into bean dip or hummus much more interesting by taking a close look at some whole beans before you reduce them to paste. The directions are very detailed, but this whole lab can be completed in the time it takes to explain the onside kick.
Of course, if you have only pre-mashed refried beans in your pantry, it’s too late. Then again, if you are using canned refried beans for your recipe, you are probably not living in the moment or sweating the details right now. That’s OK. Go watch the game and let us know when someone scores. Continue reading
This month we introduce a new feature to the Botanist in the Kitchen: Botany Lab of the Month, where you can explore plant structures while you cook. In our inaugural edition, Katherine explains why she would like to add her nominee, Solanum tuberosum, to the list of white guys vying for Best Supporting Actor.
In one of this year’s biggest and best movies, Matt Damon was saved by a potato, and suddenly botanists everywhere had their very own action hero. It’s not like we nearly broke Twitter, but when the trailer came out, with Damon proclaiming his fearsome botany powers, my feed exploded with photos of all kinds of people from all over the world tagged #Iamabotanist. The hashtag had emerged a year earlier as a call to arms for a scrappy band of plant scientists on a mission to reclaim the name Botanist and defend dwindling patches of territory still held within university curricula. Dr. Chris Martine of Bucknell University, a plant science education hero himself, inspired the movement, and it was growing pretty steadily on its own. Then came the trailer for The Martian, with Matt Damon as Mark Watney, botanizing the shit out of impossible circumstances and lending some impressive muscle to the cause. The botanical community erupted with joyous optimism, and the hashtag campaign was unstoppable. Could The Martian make plants seem cool to a broader public? Early anecdotes suggest it’s possible, and Dr. Martine is naming a newly described plant species (a close potato relative) for Astronaut Mark Watney.
In the film, that potato – or actually box of potatoes – was among the rations sent by NASA to comfort the crew on Thanksgiving during a very long mission to Mars. After an accident, when the rest of the crew leaves him for dead, Watney has to generate calories as fast as he can. It’s a beautiful moment in the movie when he finds the potatoes. In a strange and scary world, Mark has found a box of old friends. They are the only living creatures on the planet besides Mark (and his own microbes), and they are fitting companions: earthy, comforting, resourceful, and perpetually underestimated. At this point in the movie, though, the feature he values most is their eyes. Continue reading
