Today in the modern world we take freezers, and the frozen results of freezers for granted. But in ancient times, cold drinks, frozen desserts, and chilled tropical cocktails were a luxury unknown to most people. However the idea of artificially freezing goods is nothing new. As far back as 400 BC, the ancient Persians built special freezers called yakhchals. Yakhchals were large buildings used for storage of ice and foodstuffs during the hot Persian summers. Typically they were around 60 feet tall, and had a large subterranean storage space dug out from under it. The Yakhchal itself was made from a special type of mud clay called sarooj which was composed of clay, sand, lime, goat hair, egg whites, and ash mixed in a special proportion which made it extremely resistant to heat transfer. In other words the inside stayed cool, while heat from the outside was prevented from entering the building because of the thick insulated walls. This combined with the subterranean storage ensured that whatever goods were stored in the pit stayed cool, as temperatures below ground level are usually around the 60 to 65 degree Fahrenheit range. However, these designs were not what made a yakhchal a freezer. There was one other brilliant design feature which ensured that the yakhchal would stay frosty all year long.
At the top of the dome was a small hole, or series of small holes called windcatchers. Typically windcatchers were pointed in the direction of the prevailing winds. Due to its conical shape there was always a negative pressure gradient inside the yakhchal. According to Bernoulli’s Law air flow at a high pressure will always move toward areas of low pressure. Thus air from the outside was constantly flowing through the yakhchal. In addition, according to Venturi’s Principal, whenever air flows through a small hole, the smaller the hole, the greater the speed of the flow. The small hole, or series of holes of the yakhchal ensured that air passed into it at great flows. What resulted was a great amount of outside air entering into the yakhchal at high speeds. While the air itself wasn’t cool, the flows at which it was being entrained into the yakhchal created temperatures that were below freezing. Typically the windcatchers were cut in such a way that the incoming jet of air would be directed onto the storage pit.
The ancient Persians primarily used their yakhchals for storing ice and foodstuffs. During the summer, Persian nobles often enjoyed a refreshing frozen treat called faloodeh (pictured above), which is made from thin noodles with syrup made from sugar and rose water, then flavored with lemon, lime, fruits, almond, pistachio, and other flavorings. Due to the Persian’s freezing technology, faloodeh (which is still popular today) goes down in history as one of the first frozen desserts. The practice of building and using yakhchals continued up to the 20th century, when they were eventually replaced with modern freezers and refrigerators.
Okay I just saw the most beautiful NaruSasu video and I’d like to point out a few things…
Firstly, is this…
LOOK AT THEM.
They’re so beautiful I could cry. Itachi is officially my hero. He ships them so hard.
Next is this…
Sasuke cut the eggs which splits apart the NaruSasuness. Heart broke a little, but then I realized…
HE EATS THE NARUTO EGG.
I mean, C'MON!
Sasuke didn’t eat the uchiha symbol and leave Naruto’s insignia to sit on the plate and not give it a second thought. NO, he takes the symbol that represents Naruto and PUTS IT IN HIS MOUTH AND EATS IT.
Hey, hey guys, Naruto’s inside him. HEHEHE.
And after he’s done, he wakes up from his “dream” and BOOM! Naruto’s there like c'mon sleeping beauty time to wake up and kill something. Whats cute is that he wakes Sasuke up by flicking his forehead. Something Sasuke adores due to the influence of his big brother.
Lastly, I notice this…
Sasuke’s asking Naruto to wait for him! Instead of ignoring him and passing him off as an illusion or something stupid he pleads with Naruto to wait and chases after him! WHAT.
Few people know this, but I am Filipino. My mother was born in the Philippines and she came to the U.S. when she was a teenager.
When I was younger, I used to occasionally help my Lola (grandma in English) cook traditional Filipino food for special occasions. One of those dishes is called “lumpia” and it’s essentially an egg roll.
My Lola had a special but simple mixture of meats and spices that she used for her preparation and I have fond memories of rolling and stuffing lumpia in her kitchen in Los Angeles. I have even more fond memories of eating lumpia - usually to the point of spoiling my dinner.
We took my Lola out for lunch on the lake this weekend and she gave us the recipe and supplies and for the first time ever, we made them and they are delicious!!!
Such a special and yummy tradition to pass down to the girls.
