(LUNJEVICA, Serbia-AFP) - A delicacy for medieval monarchs, a plate for the poorest and a treat for Tito, animal testicles, with a pinch of humour, are back on the menu, at least at one Serbian food festival.

A visitor needs no road signs to reach the tiny central village of Lunjevica, population 500. They can follow the smoke and smells from the barbecues and kettles at the 10th unofficial testicle-cooking "world championship".

"In our region, we have cooked testicles for ages: our fathers prepared them, our grandfathers before them," local farmer Dragan Todorovic said, slicing a set or horse testicles.

The challenge for this year's 20-some competitors was to make the best "balls-goulash", a twist on the ubiquitous regional stew but replacing classic meat cuts with testicles from rams, calves, bulls, donkeys, horses or other animals.

Some say the testicles should be diced into tiny pieces and soaked in wine for at least 30 minutes for the right consistency before simmered with the onions, garlic, peppers, tomatoes and herbs.

"Beware. They should be cut diagonally, otherwise they lose their aphrodisiac effect," warned Zdravko Djuric, a competitor from northern Serbia.

Local lore considers testicles an aphrodisiac, given their naturally high testosterone level, and organisers tap into this reputation.
"Better for the libido than any Viagra," reads one of the slogans for the festival, which draws up to a thousand people, many from abroad.
"It's so totally crazy, I had to be here," said German cook Andre Niediek, a chef in a Cologne restaurant, stirring a pot of bull testicles spiced with "fine Serbian paprika".

His own secret is timing. "Two and a half hours at least. This is not a quick lunch or fast food meal."

Some come "out of curiosity", like Zoran Jeftic from the capital Belgrade who found the stewed glands "tasted similar to chicken."

The festival's founder Ljubomir Erovic says the event is not only a culinary competition but a bid to sweep away prejudice against Serbia that dates back to the 1990s wars in the Balkans. So he injects lots of humour, starting with the official poster -- a drawing of a pot-bellied, mustachioed chef with his own testicles drooping right into his boiling cauldron of stew.

"The French boast with the Tour de France, and we boast with balls," joked farmer Todorovic.

Erovic, who has authored a book entitled "Cooking with Balls", said the delicacy was a favourite with many past notables, including Serbia's 19th-century ruler prince Milos and communist Yugoslavia's strongman Josip Broz Tito.

The four-member jury includes an American, Boston filmmaker Anna Wexler, its sole woman and non-Serb who discovered the festival "googling weird things late at night".

When she contacted Erovic, he invited her to the event where she has been a regular since 2009. "Every year I come all the way out here just to judge the balls," she said laughing.

A ram's testicles stew was this year's winner, but all entries were sampled at gala dinner where cocktail nibbles were grilled lamb testicles rustled up by a Danish competitor.

An annual tongue-in-cheek prize is also awarded to the "person with the biggest balls", which this year pits German Chancellor Angela Merkel against US intelligence leaker Edward Snowden. Voting goes through the end of the year on the festival's website.

Among previous winners were US President Barack Obama in 2010 and Wikileaks founder Julian Assange in 2011.

  • Batalla del Vino — Haro, Spain

    Every year on June 29 in the heart of La Rioja, Spain, the Batalla del Vino takes place. What began as a medieval dispute over a mountain range between neighboring towns has evolved into a celebration with hundreds of Spaniards soaking each other by any means possible. Traditionally dressed in all white except for a red bandana, they proceed to pour gallons of the area’s famous red wine until everyone is stained purple and undoubtedly tipsy.  <a href="http://www.thedailymeal.com/world-s-most-unusual-food-festivals?utm_source=huffington%2Bpost&utm_medium=partner&utm_campaign=foodfests" target="_hplink"><strong>Click here to see All of the World's Most Unusual Food Festivals</strong></a> <em>Credit: WikimediaCommons/BigSus</em>

  • World Black Pudding Throwing Championships — Ramsbottom, England

    Despite the name, there isn’t actually any pudding thrown in this contest… at least not as most Americans know it. The ancient rivalry between Yorkshire and Lancashire is played out annually at the World Black Pudding Throwing Championships by hurling black pudding — a type of sausage — at Yorkshire pudding, an English dish made from batter and usually served with roast meat and gravy. Because who doesn’t love trying to knock stuff down by hurling sausages? <em>Credit: WikimediaCommons/Paul Anderson</em>

  • Cheese-Rolling — Copper’s Hill, Britain

    The cheese-rolling festival is definitely one of the more unique food festivals around. Here's how it works: On top of an incredibly steep hill stand several large wheels of cheese. Competitors race to catch their wheel of cheese as it rolls down the hill with a one-second head start. The hill is so steep that the cheese can reach speeds of up to 70 miles per hour! <em>Credit: Wikimedia Commons/Dave Farrance</em>

  • Rocky Mountain Oyster Festival — Throckmorton, Texas

    Don’t expect to find any seafood here; some of you may have already guessed, but the Rocky Mountain Oyster Festival is actually a testicle festival. Cow testicles are considered a delicacy by many and Texans show their appreciation in a cook-off to see who can make the best "calf fries" aka mountain oysters.  <a href="http://www.flickr.com/photos/sklathill/" target="_hplink"><em>Credit: Flickr/Sklathill</em></a>

  • La Tomatina — Bruñol, Spain

    In Italy, they throw oranges. In Spain, they throw tomatoes. On the last Wednesday of August, bring your gloves and goggles and get rid of any pent-up aggression by throwing tomatoes at complete strangers for an hour. The fight can’t begin until someone manages to climb a two-story-high greased pole and throw down the ham sitting at the top. After that, it's every person for themselves in the world’s biggest food fight. <em>Credit: WikimediaCommons/Graham McLellan</em>

  • SPAM Jam Festival — Waikiki, Hawaii

    Hawaiians love SPAM. In fact, more than 7 million cans of the pink meat are consumed in Hawaii every year.  SPAM Jam brings together SPAM lovers and celebrates the "spiced ham" that became popular during the meat scarcity of WWII. If you haven’t tasted it yet, you might consider it —but be warned, it might not be what you expect.  <em>Credit: WikimediaCommons/Neil Motteram</em>

  • Night of the Radishes — Oaxaca, Mexico

    Here is another food festival where the main goal isn’t actually eating. Night of the Radishes is celebrated every year on Dec. 23, and radishes are specially grown for the event and kept in the ground past harvest season so they develop a strange shape and become unusually large. The unusual sculptures that are created using the radishes make it worth a trip.  <a href="http://www.thedailymeal.com/world-s-most-unusual-food-festivals?utm_source=huffington%2Bpost&utm_medium=partner&utm_campaign=foodfests" target="_hplink"><strong>Click here to see more of The World's Most Unusual Food Festivals</strong></a> <a href="http://www.flickr.com/photos/drewleavy/" target="_hplink"><em>Credit: Flickr/drewleavy</em></a>
