Here at Khymos I aim to cover things related to food and chemistry, and as I stumbled over a periodic table of cupcakes (with clickable “elements” linked to recipes) I couldn’t resist to dig a little deeper. And look what I found! The periodic table of elements is iconic, but the periodic table has also become an organizing metaphor for all sorts of things, including food. The Internet database of periodic tables holds more periodic tables than you could ever dream of, but it’s not complete – at least not with regards to food. Here are the food related periodic tables that I’ve been able to find. Fun? Yes! Useful? No, not really At the end of the post I’ve also included examples of how the real periodic table of elements can be illustrated in a more or less edible fashion. All images are linked to the page where I found them. Are you aware of other periodic tables of food? Please let me know and I’ll include them in this post.

In case you wondered, it’s a periodic table of breakfast cereals!

Condiments that periodically go bad

Cupcakes – what else! And each “element” is linked to a recipe. Very well made!

The real periodic table of elements represented in food
If you think fitting some kind of food into a periodic table is stretching a little too far, why not make an edible version of the real periodic table? In the process you may even learn the name of some elements

A nice idea for Halloween?

As the name suggests, the TGIF posts are a little less serious than what I otherwise post here at Khymos. I hope you enjoy it

Finally it’s time for a new round of TGRWT. It’s the 18th round and the host this time is Aidan Brooks, a trainee chef who works in Spain. In his blog he’s touched upon flavor pairing several times and also wrote a blog post on the same topic for “Word of mouth”, the food blog of The Guardian. The foods to pair this time are plum and blue cheese, and as usual you can read more about how to participate in the announcement post. The deadline for submissions is September 1st.

TGRWT is not a competition, but Aidan wanted to add a little competitive element to round of the meal. So his challenge to you (in addition to the normal TGRWT contributions) is to make a dessert using plum and blue cheese which additionally incorporates any two of the following flavors: salty, sour, bitter, umami, pungent, astringent. He will pick a winner and the prize is quite cool: he’ll make a restaurant level version of it, with the name of the winner incorporated in the title of the dish and try to get this on the menu at Restaurante Ferrero where he works as a Pastry Chef on the team of Paco Morales, Spain’s “Chef of the Year 2009″.

Regarding the chemistry behind this pairing there is (for once) actually some informartion available. From a paper on gorgonzola I’ve learnt that 2-nonanone, 1-octen-3-ol, 2-heptanol, ethyl hexanoate, methylanisole and 2-heptanone are the most important impact odorants of natural and creamy Gorgonzola cheese [1]. For plums I haven’t found anything on impact odorants in fresh plums, but there is a paper on impact odorants in candied plums [2], and comparing the two papers I find that phenyl acetaldehyde, ethyl benzoate and ethyl octanoate are present in both Gorgonzola cheese and candied plums and have odor activity values greater than 1. There’s another paper as well comparing two plum varieties were the abstract mentions odor unit values, but alas – I don’t have access to the full text (maybe someone with access could check it and give me a hint about the impact odorants?) [3]. There are probably some differences between fresh and candied plums, but at least this shows that you’re safe if you want to use candied plums when cooking up something with blue cheese.
