Because it gives you a recipe for salted water:

When salting water for cooking, use 1 tablespoon of salt for every 4 quarts of water.

And the eight hundred reviews of the recipe.

* As a Canadian, I am on the metric system and have no idea what a quart is. Furthermore, I had to substitute beavers for the salt, and beer for water. The boiling process caused my igloo to melt, leaving me homeless. Two forks.

* I used iodized sea salt and added an extra 1/8 tsp. Definitely upped the ante. My guests were begging me for the recipe.

* I have been making something similar to this since it first appeared in Gourmet magazine in 1992. But I misplaced the recipe years ago and have had to improvise since, with out much luck. Thank you Epicurious for reacquainting me with this oldie but goody!

My own review: this website gave me my review for lemon icing. Proceed with caution.
