Our tongues are so acutely sensitive to these that companies trying to lower the sodium content of their foods this way actually have to use a mix of regular salt and potassium salt so it's less noticeable.

我们的舌头对这些非常敏感，以图以这种方式降低食物钠含量的公司其实必须要使用普通盐和钾盐的混合物，这样就不那么明显了。

Took it home and boiled it in potash, Eph used to say; and there it is, just as good as it was thirty years ago.

伊夫常说，拿回家用钾盐煮了，你看，和三十年前一样好。

那里有钾盐矿藏。

That life hack is to switch the brand of salt you use in cooking and at the table to a low sodium salt that's potassium enriched, has anywhere from 15 to 50% potassium in it.

那个生活小窍门就是， 把你烹饪和餐桌上使用的盐换成低钠高钾盐，这种盐含有15%到50%的钾。

Now, that water dissolves the potash salt, so we get a briny solution down here.

现在，这些水溶解了钾盐，所以我们在这里得到了一种咸溶液。
