(1) 硬糖在技术上是由糖制成的玻璃!

(2) 糖的熬制分为三个阶段,达到的最高温度决定了最终糖果的物理性质(我认为这主要是糖混合物中剩余水分多少的功能)。

(3) 如果你观看视频,你就会明白为什么硬糖的边缘总是有一个环。这是我以前不知道的。

请享用。也许我稍后会写一篇关于你吃完糖后身体如何处理所有糖分的文章。:)

"Life creates [the Force], makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter," Yoda explains in The Empire Strikes Back, gesturing to Luke's physical body. This quote is striking because of the apt juxtaposition of the wonder of life with its often disgusting vessel. Like many other animals, we secrete, excrete, expectorate, defecate, flatulate, regurgitate, urinate, circulate, masticate, menstruate, ejaculate, and ventilate. We are filled with gas and feces and blood and guts and mucus and any number of rude things. Life as we know it is possible because of the countless impolite things we do every day. Are we luminous beings? Perhaps, but that's neither here nor there. This blog is about the crude matter that keeps us alive.
