Henry David Thoreau : Wild Apples: The History of the Apple Tree (1862)

"It is remarkable how closely the history of the Apple-tree is connected with that of man. The geologist tells us that the order of the Rosaceae, which includes the Apple, also the true Grasses, and the Labiatae, or Mints, were introduced only a short time previous to the appearance of man on the globe."

"They must be eaten in the fields, when your system is all aglow with exercise, when the frosty weather nips your fingers, the wind rattles the bare boughs or rustles the few remaining leaves, and the jay is heard screaming around. What is sour in the house a bracing walk makes sweet. Some of these apples might be labelled, "To be eaten in the wind.""


"Thus the cows create their own shade and food; and the tree, its hour-glass being inverted, lives a second life, as it were."

The dinner is organized around a six course menu. Recipes offered range from a tactile and perfumed Futurist dish to cheeses based on Sol Lewitt’s “Forms derived from a cube” (Nicolas Boulard's Specific Cheeses, 2009). Other recipes include a cucumber salad by Louise Bourgeois (1977), a steak tartare by Marcel Duchamp (1961), Basque Bass from Gordon Matta-Clark’s restaurant Food (1971), Clouds by Geoff Hendricks (1969), Toffee Pinecones by Salvatore Dali (1973), Fig Pervert by Philip Corner (1965), and two recipes from the first monograph on ice cream -- Emy’s L’Art de bien faire les glaces d’office, Paris: 1768.



Ben Kinmont (Born 1963 Burlington, Vermont, USA) is interested in interpersonal communication as a means of addressing the problems of contemporary society. His sculptures and actions attempt to establish a direct, personal relationship between the artist and the viewer, using the work as a mediator. If art is supposed to be an agency of intellectual and emotional challenge, then the artist concludes that the audience should also be addressed beyond the institutional frame of the gallery and the museum, and that contact should be more direct. Kinmont also runs a bookselling business specializing in 15th – early 19th century books about food and wine.

The letter from Yvonne Rainer to Jeffrey Deitch:

November 9, 2011
To Jeffrey Deitch:
I am writing to protest the “entertainment” about to be provided by Marina Abramovic at the upcoming donor gala at the Museum of Contemporary Art. It has come to my attention that a number of young people will be ensconced under the diners’ tables on lazy Susans and also be required to display their nude bodies under fake skeletons.
This description is reminiscent of “Salo,” Pasolini’s controversial film of 1975 that dealt with sadism and sexual abuse of a group of adolescents at the hands of a bunch of post-war fascists. Reluctant as I am to dignify Abramovic by mentioning Pasolini in the same breath, the latter at least had a socially credible justification in the cause of anti-fascism. Abramovic and MOCA have no such credibility, only a flimsy personal rationale about eye contact. Subjecting her performers to public humiliation at the hands of a bunch of frolicking donors is yet another example of the Museum’s callousness and greed and Ms Abramovic’s obliviousness to differences in context and to some of the implications of transposing her own powerful performances to the bodies of others. An exhibition is one thing — this is not a critique of Abramovic’s work in general — but titillation for wealthy diners as a means of raising money is another.
Ms Abramovic is so wedded to her original vision that she – and by extension, the Museum director and curators — doesn’t see the egregious associations for the performers, who, though willing, will be exploited nonetheless. Their desperate voluntarism says something about the generally exploitative conditions of the art world such that people are willing to become victims of a celebrity artist in the hopes of somehow breaking into the show biz themselves. And at sub-minimal wages for the performers, the event verges on economic exploitation and criminality.
This grotesque spectacle promises to be truly embarrassing. We the undersigned wish to express our dismay that an institution that we have supported can stoop to such degrading methods of fund raising. Can other institutions be far behind? Must we re-name MOCA “MODFR” or the Museum of Degenerate Fund Raising?
Sincerely,
Yvonne Rainer

 
FYI: (http://en.wikipedia.org/wiki/Yvonne_Rainer)

In 1965, as a reaction to many of the previously stated feelings, Rainer created her "No Manifesto," which was a strategy formulated to demystify dance:

NO to spectacle.
No to virtuosity.
No to transformations and magic and make-believe.
No to the glamour and transcendency of the star image.
No to the heroic.
No to the anti-heroic.
No to trash imagery.
No to involvement of performer or spectator,
No to style.
No to camp.
No to seduction of spectator by the wiles of the performer.
No to eccentricity.
No to moving or being moved.

Washing out your mouth with soap

Image courtesy of Stockbyte/Getty

Washing out mouth with soap is a form of physical punishment. It is most commonly administered to children for actions such as cursing, lying, or talking back. It is considered symbolic of cleansing out a dirty mouth but is used primarily because some people feel that the foul taste of soap is an effective deterrent to unacceptable behavior. It was a common method of punishment in the first half of the 20th century but has declined in popularity significantly since the 1960s. Historically, it has been practiced primarily in the United Kingdom, Australia and United States. Today it is a controversial practice, with some parents, child experts, and other persons who spend time around children practicing and/or advocating for it, others refusing the practice, and some even opposing its use by others. Opposition to this punishment has grown in recent decades as its use has declined.
from : http://en.wikipedia.org/wiki/Washing_out_mouth_with_soap


For nice words coming out of your mouth, try this:
Boil 2.5 cups of water. Add in 1 teaspoon of fresh mint leaves, 1 teaspoon of rosemary leaves, ad 1 teaspoon of anise seeds. Let this boil for about 20 minutes. Once it is cooled, you've got your mouthwash!

Breeding hybrid fruits

Making hybrids. Scary though interesting ideas.
Like the Pomato (Potato + Tomato) which roots and fruits are both growing common edible on the same tree.

Feeding tomatoes with the same food we eat (fish, meat, various other rootstocks) is an other interesting idea but brings up more SciFi memories.

Counter cultural movements can be told through their stomachs

Food provided during Occupy Wall Street, oct 16th 2011

The history of counter cultural movements can be told through their stomachs. Sustenance is an oppressed group’s most basic demand, and protesters have often employed it to help voice their beef with the mainstream. The rising cost of bread and salt helped set off the French Revolution. Salt was a key element in Gandhi’s nonviolent protest against the British. Sixties-era communards gathered around recipes like “Heart in Surprising Sauce” or “Brotherhood Spirit in Flesh Soup.” Even Coca-Cola took on a symbolic role during the lunch counter sit-ins of the 1960s. Before it was reclaimed by the modern-day Republican fringe, the Tea Party was, of course, an 18th century protest against tea taxes.

Enter and be damned! HELL's CAFE, PARIS

MARAIS
Hell's Swells

A hot spot called Hell's Café lured 19th-century Parisians to the city's Montmartre neighborhood—like the Marais—on the Right Bank of the Seine. With plaster lost souls writhing on its walls and a bug-eyed devil's head for a front door, le Café de l'Enfer may have been one of the world's first theme restaurants. According to one 1899 visitor, the café's doorman—in a Satan suit—welcomed diners with the greeting, "Enter and be damned!" Hell's waiters also dressed as devils. An order for three black coffees spiked with cognac was shrieked back to the kitchen as: "Three seething bumpers of molten sins, with a dash of brimstone intensifier!"

Take out to your restaurant

FOOD FACILITY

by Martí Guixé and Mediamatic

Oct-Dec. 2005

Food Facility was a working prototype restaurant where the central kitchen is replaced by kitchens of existing take-out restaurants in the area. You were invited to make a choice from the menu of these take-outs and consume your order at Food Facility.

A food adviser placing the order for the customers.

A SHORT HISTORY OF PRIVATE FOOD IN A PUBLIC SPACE: The relationship between the locative restaurant and the non-locative kitchen was firmly based in history. Inside as well as outside of the art world.

Just a few examples from the Netherlands: In 1990 the legendary Supperclub and its chef Thor Vos organized an evening where the food was ordered from take-outs, including Mac Donalds.
During the conceptualization the Lloyd Hotel in Amsterdam considered not opening a kitchen and having their guests choose from various take-out menu's in its vicinity. The idea was finally abandoned for its 24 hour à la carte restaurant.
Dutch artist Eric Wie was the first to ccreate a take-out food restaurant in a public space during the 1996 Kunstvlaai he created Arie Vederci, a restaurant where you could have pizza delivered.
In Groningen between 1998 and 2003 an artist collective named MPD Export organized similar evenings under the name No Kitchen United in different locations, one evening serving up to 150 guests! a selection of take-out foods.

Also well known is the way millions of lunches are delivered every day in the Indian city of Mumbai through a system of Dabawallas that very closely resembles the ideas unlying these various projects.

In China certain street corner vendors work excactly in this style, selling food that is ordered from little take-out kitchens in the neighbourhood. The only thing they provide is chopsticks, a small plastic kitchentable and chair.

Cucina Futurista

"
Futurist meals comprised a cuisine and style of dining advocated by some members of the Futurist movement, particularly in Italy. These meals were first proposed in Filippo Tommaso Marinetti and Fillia's Manifesto of Futurist Cooking, published in the Turin Gazzetta del Popolo on December 28, 1930.
The Futurist movement recognized that people "think, dream and act according to what they eat and drink" so cooking and eating needed to become subservient to the proper aesthetic experience that Futurism favored. Revolutionary in its expectations of overturning set patterns, some of its more interesting ideas for the realm of cuisine were:

• No more pasta, as it causes lassitude, pessimism and lack of passion

"I don’t do lunch. I don’t like lunch, I don’t understand it. It seems to completely break your day, and things I do seem to take weeks, and if you start working on something, you want to continue to work. So I sort of work and work and the other people go out to lunch and they do things, and I just work my way through. It’s not very exciting. And people who come by, like you, have a cup of coffee and sit and they chat. I’m a real cocktail party kind of person. I prefer cocktail parties to anything else. With a cocktail party people can talk, and they’re not trapped." Lawrence Weiner interviewed by Thessaly La Force, The Paris Review.

De la gélatine fabriquée à partir de clones de gènes humains

De nouvelles méthodes pour produire de la gélatine à partir d'un clonage de protéine humaine :

Principalement utilisée dans l'industrie pharmaceutique (gélules etc), dans l'industrie alimentaire, la fabrication de produits cosmétiques ou de photographies argentiques, la gélatine était jusqu'à aujourd'hui issue de l'extraction de collagène d'origine animale (peau, os, tendons ... principalement bovine ou porcine). 

La moelle épinière de ces divers animaux (malades ou souvent élevés dans des conditions peu contrôlées) étant le terrain de nombreux dangers potentiels, la synthèse artificielle et d'origine humaine pourrait prévenir certaines réactions pathogènes.

Les bonbons Lifesavers® possèdent cette particularité de s'allumer à l'intérieur de la bouche quand on les brise avec les dents. Mais la mastication lumineuse intrigue encore bon nombre de chercheurs tribologues.


Pour explication, les cristaux de sucre éclatent et mettent en friction des polarités opposées ce qui produit des rayons ultraviolets qui sont rendus visibles grâce aux huiles contenues dans le bonbon.
Note : Il faut néanmoins avoir une bouche bien sèche pour que cela fonctionne.
