Chakkoli is a dish made with rice flour balls and curry spices with meat, usually shrimps.
 This is a well known dish among the Muslim population in Kanyakumari District in Tamil Nadu, India.
 It is a rare traditional dish and it is usually consumed along with ginger flavored black tea.
 Making Chakkoli is a very time consuming process.
 The dough for the tiny rice balls is prepared by adding roasted rice flour in boiling water with grated coconut and salt and kneading thoroughly.

Jumpsuit is the name of an American rock and roll band from Chicago, Illinois.
 Together since the late 1970s when they were little more than casio and tambourine street performers, Jumpsuit has gone on to release several 7-inch singles throughout the 90s and 2000s, as well as a full-length compact disc in 2005.
 Jumpsuit also stars in a television cartoon series that relates their trials and tribulations that come as a result of discovering a time machine.
 In the series, the members of Jumpsuit attempt to use their time machine to right past wrongs and regrets in their lives; however they are usually foiled by mechanical doppelgängers that follow them through the fourth dimension.
 Jumpsuit's live rock shows are often presented as live-action recreations of events from the cartoon.
 Their most recent TV appearance on Chic-A-Go-Go brought out a new generation of fans, many still in diapers.
List of Palestinian records lists national and international records achieved by people, groups or institutions from the Palestinian territories.
 For Example, The largest Qatayef ever made had a net weight of 104.75 kg (230 lb), which was organized by the Bethlehem Chamber of Commerce and Industry and cooked by the DANA bakery (Palestine) in Bethlehem, Palestine, on 27 August 2010.
 Also, Three dedicated women in the West Bank are hoping to break the Guinness World Record for the biggest straw tray ever constructed in history.
 The project, which the women have been working on for over two years, was begun by Rose Hamad, a resident of a small village near the city of Ramallah.
 The straw tray is already the largest such tray in Palestine, and its construction continues.
 Also, Palestinian chefs were able to get into the Guinness Book of World Records as the world’s largest salad when they have prepared a large bowl of the traditional Arabic dish Tabouleh at the Friend’s School in the Palestinian city of Ramallah, Friday, 9 June 2006.
 The traditional dish made of lettuce, tomato, olive oil, cracked wheat and mint is a new record for the dish, according to organisers of the culinary achievement.
 Also, a group of Palestinian seamstresses in Hebron have produced the largest traditional dress ever sewn.
 About 150 women helped make the dress which is 32.6m (107ft) long and 18.1m (59.4ft) wide.
 It is hoped that the dress will secure a place in the Guinness Book of World records and promote local handicrafts.
Set in 1990, Jenny Brix lives in Iowa City.
 She is a history buff.
 She even has a Ronald Reagan picture when he was in his 20s as a lifeguard!
 When she goes to a meeting, a very old professor has a heart attack.
 Panicking, she uses CPR on him, thus saving his life.
 After a few stops to the hospital, he asks her which US president she likes best.
 She answers Ronald Reagan.
 So then the professor tells her that she can go back in time and meet him.
 She is shocked, but the professor keeps telling her it's true.
 She finally believes him, sort of.
 The professor takes her to Dixon, Illinois, Reagan's childhood home.
 There the professor tells her she has 80 hours to stay out of the timezone, or her body will be used to the other timezones and can't come back to present day (1990).
 When she goes into the time machine, it actually is set on 1832, instead of 1932 (where she was going).
 She then meets Abraham Lincoln (who develops a little crush on her), and Chief Black Hawk during the Black Hawk War.
 After all of that is straightened out, she goes to 1932 with less than half the time left she started with.
 Once she gets there she sees a young, handsome Ronald Reagan going past her to save a person from drowning.
 She then gets some friends, Scooter and Betsy.
 They say there is a dance at Dixon's run down, old high school.
 There she dances with Ronald and his brother.
 While dancing with Ronald, she falls down the steps with him.
 They then get a crush on each other.
 After going on a few dates, she has to go to her original timezone.
 She and Ronald have a sad exchange (Ronald doesn't know about the time traveling) when she has to leave.
 Jenny then takes Scooter and Betsy to Lowell Park, where she shows them the time machine.
 She then leaves, leaving the others dumbfounded.
 When she comes back, professor says he is Scooter, and spent the rest of his life finding things about the time machine after she left until he finally made the time machine.

A butter dish is defined as "a usually round or rectangular dish often with a drainer and a cover for holding butter at table".
 Before refrigerators existed, a covered dish made of crystal, silver, or china housed the butter.
 The first butter dish was made by Simpson, Hall, Miller, and Co. around 1880 in Connecticut, out of silver.
 These butter dishes were made to hold the traditional round shape of butter at the time and came with an "ice chamber" to keep the butter cold.
 Another type of butter dish, a French butter dish, keeps butter fresh by using water to keep the butter away from the air, thereby keeping it fresh.
 The water is placed into the base of the dish and the butter is put into a bell-shaped lid, creating an air seal.
Peking duck is a dish from Beijing that has been prepared since the imperial era.
 The meat is characterized by its thin, crisp skin, with authentic versions of the dish serving mostly the skin and little meat, sliced in front of the diners by the cook.
 Ducks bred specially for the dish are slaughtered after 65 days and seasoned before being roasted in a closed or hung oven.
 The meat is eaten with spring onion, cucumber and sweet bean sauce with pancakes rolled around the fillings.
 Sometimes pickled radish is also inside, and other sauces (like hoisin sauce) can be used.
Time Machine Chefs is a television special that originally aired on ABC in which four celebrity chefs were challenged to cook against each other using ingredients and tools belonging to a historical era.
 The program was divided into two rounds; the first challenged the chefs to create a Peking duck in 16th century China during the Ming Dynasty and the second saw the chefs create a Cockentrice in 1532 in the House of Tudor.
In each round, Guy assigns a dish and issues a challenge to the chefs.
 Then they have 30 minutes to shop for ingredients from the market, prepare, and plate their dishes.
 The chefs must cook their dishes and complete four platings (three for the judges and one "beauty plate") before time runs out.
 At the end of each round, the judges will taste and evaluate the dishes and select one chef to be "checked out" - eliminated from the game with no winnings.
 The judges are introduced by Guy during the first round.
 There are two judging tables for the judges, one when the chefs are shopping and cooking and one during judgings and eliminations.
