Refrigerator Organization

Are you like me and stuff everything everywhere (except for those certain items that "have their place")?

Well, Kenji Lopez-Alt from Serious Eats has news for you and me - where we store stuff in the fridge (why does fridge have a "d" and refrigerator does not?) will make a difference to the quality and freshness not to mention healthiness of our food.

The Food Lab: How to Organize Your Refrigerator for Better Food Storage
I think I am going to rethink my cold storage this weekend and upend my status quo!

Drink coffee for your health!

A review of the literature seems to indicate that there is a positive benefit to a few cups of coffee a day - prevents type 2 diabetes, lowers body weight and waist circumference, and lowers the risk of cardiovascular disease!

Here is the paper (hurray for open access): 
How coffee affects metabolic syndrome and its componentsB. Baspinar,*a  
Food Funct., 2017,8, 2089-2101

and a cool summary of the findings in this diagram

Time for summer drinks - gin and tonic!!

Here is an excellent explanation as to why gin + tonic does not taste like gin or tonic but something more subtle;

In contrast, a rum and coke tastes like rum + coke.

Better cooking through science...

I have become addicted to J. Kenji Lopez-Alt's Food lab posts on Serious Eats. He breaks down cooking and baking to its elements and tweaks them to create the best versions possible.

 I love the scientific methods in his Yorkshire Pudding post - hypothesize, experiment, conclude.

His latest is on how to fry your stewed beef to create the best Maillard reaction browning with the least amount of dryout.

If you want to be a better cook - READ HIS STUFF!!

There is also a book!

Time-lapse Chemistry and Food!

One of our grad students, Dorea Reeser, convinced C&EN to publish her time-lapse video of  a chemistry experiment:

She calls it "Chem-lapsed" and it is pretty cool. Her first one uses tomato juice and bromine water to create rainbows in a test tube. Watch and learn!

We hope there are many more in the pipeline...

food pairing vs anti food pairing

As an silly example of flavour pairing, here is a video from the National Post:

Can you nutella it?

In 2012, I  linked to an ACS webinar on food pairing and to the website to highlight how sometimes some flavours work well together. The Foodpairing website also has a video explaining how to use it.

The Wiki page on food pairing has more info and links.

People have also use flavour pairing for wines:
Here is a food pairing interactive from Scientific American.

But now a group of scientists have done research on how flavours that do not complement each other can also come together to make delicious food.

Spices form the basis of food pairing in Indian cuisine

"Culinary practices are influenced by climate, culture, history and geography. Molecular composition of recipes in a cuisine reveals patterns in food preferences. Indian cuisine encompasses a number of diverse sub-cuisines separated by geographies, climates and cultures. Its culinary system has a long history of health-centric dietary practices focused on disease prevention and promotion of health. We study food pairing in recipes of Indian cuisine to show that, in contrast to positive food pairing reported in some Western cuisines, Indian cuisine has a strong signature of negative food pairing; more the extent of flavor sharing between any two ingredients, lesser their co-occurrence. This feature is independent of recipe size and is not explained by ingredient category-based recipe constitution alone. Ingredient frequency emerged as the dominant factor specifying the characteristic flavor sharing pattern of the cuisine. Spices, individually and as a category, form the basis of ingredient composition in Indian cuisine. We also present a culinary evolution model which reproduces ingredient use distribution as well as negative food pairing of the cuisine. Our study provides a basis for designing novel signature recipes, healthy recipe alterations and recipe recommender systems."

Food pairing works on the basis that foods with similar chemicals in them will taste well together. Indian cuisine works the opposite "more the extent of flavor sharing between any two ingredients, lesser their co-occurrence".  One reason this works is that the curries often made up of many different flavours (unlike most other cuisines that only one or two spices in each dish) and these blend together to make the unique flavours.

Here are just three curry powder recipes:
