Blue Lagoon Cocktail

As to the history of this cocktail, I found only a reference to it being invented in the 1970s.

Curaçao, pronounced as if, "cure-ah-sow" (the last rhyming with "how"), is an orange flavored liqueur made from the peel of a type of bitter orange grown on the island of that same name. The island lies in the very southern part of the Caribbean, not far off the coast of Venezuela. Curaçao, the island, has a long history with the Netherlands; and indeed, it is a component country of the Kingdom of the Netherlands. The name "Curaçao" apparently goes back to a form of the word from the native inhabitants of the island. "Curaçao" (the island) was then taken over by the Spanish, but often used by Portuguese ships as a stopping place from the first half of the 1500s, and "apparently" it was the Portuguese who adapted the word to the Portuguese spelling. The Dutch came to the island during the 1600s and they have been there ever since.   

Now, you won't be condemned to death, if you don't have blue curaçao, but it is this specific drink that gives the cocktail its color and name; however, you can use triple sec. Blue curaçao "should" be available at your local liquor store, or supermarket, and it's not terribly expensive, although I'm sure there are more expensive brand names. I get mine from a neighborhood beverage store and it's only $7 a bottle. 

Ingredients:

1 1/2 ounces vodka
1 1/2 ounces blue curaçao
2 to 4 ounces lemonade (store bought or homemade*)
1 slice orange, halved 
ice 

A tall glass is best for this cocktail. Fill the glass two-thirds of the way with ice. Add the vodka, then the blue curaçao, then top off with lemonade. Put a half slice of orange into the cocktail and fix the other half slice of orange to the rim of the glass.

* For lemonade: bring 3/4 cup water to a boil. Add 2/3 cup sugar and the peel of 1 lemon; stir to make sure the sugar dissolves completely. Remove the mixture from the heat and let it sit for about 20 minutes to cool a little, then add 1 cup crushed ice. In a pitcher, add 3/4 cup lemon juice

WORD HISTORY:
Today-This compound is simply the combination of "to"^ and "day,"^^ but its true written form as one word is only from a little over a century ago, as it was long written as two words or, later, in hyphenated form. English once also had "heodæg" as a synonymous form, which meant, "this day, (of/on) this day." The close relative of "heodæg" is German "heute" (meaning, "today"), both of which are from the same Old Germanic form of two words, "hiu dagu," meaning, "this day," and which became "hiu tagu" in the high dialects. The Old High German form was "hiutu," which later became "hiute." The Old Germanic form "hiu" became the basis for modern English "he."
