Old Fashioned Ice Cream Makers²

老式冰淇淋机

Have you ever seen an old-fashioned ice cream maker¹?

你见过老式冰淇淋机吗？

Nestled inside the wooden bucket, there's a metal canister with a hand crank on top.

这种冰淇淋机带有木桶，而木桶内安装了一个顶上带手摇曲柄的金属罐。

Cranking the handle scrapes the sweet, creamy mixture from the sides of the metal canister, which sits in a bath of ice water and salt.

摇动手柄将糖和奶油的混合物从泡在冰盐水中的金属罐的一边挤出来。

But what does salt have to do with freezing?

但是盐在冰冻过程中有什么作用？

Why not just use plain ice water?

为什么不是只使用淡冰水？

The bath of salty ice water freezes ice cream faster than plain ice water could.

盆中的冰盐水能比淡冰水更快的冻结冰淇淋。

And speedy freezing does more than minimize the cranking time on a hot summer's day.

在炎日的夏天，快速制冷能够最大限度的减少摇动手柄的时间。

A fast freezing process also yields small crystals, insuring a silky texture³.

快速制冷过程也能够产生微小的冰晶，确保丝滑的口感。

Slower freezing could make big crystals with an unpleasant crunch⁴, kind of like ice cream that's gritty with freezer-burn.

较慢的制冷过程则形成大的冰晶体，使口感变差，似乎冰激凌表面因为冷冻变硬了。
