[header] How to make absinthe cocktail [title] Mix a simple blend. [step] Add 3 parts ice-cold water to 1 part absinthe. For a single serving, this is roughly 3 ounces of absinthe (or 3 shots) to 1 ounce of absinthe (or 1 shot). <sep> (A) [substeps] If you don't like the bitterness of the mixture, you can dilute it with 1 ounce of milk or cider vinegar instead. If you don't like the strong, milkier flavor, you can substitute nothing at all. (B) Place the absinthe in a cocktail shaker. [substeps] This drink will only last if you serve it in a cup, as the glasses will be fairly small, and will take up a lot of room. (C) For each single serving, stir in 1 teaspoon of sugar. [substeps] Alternately, absinthe can be sipped neat if you prefer the undiluted taste. (D) [title] Add the ingredients to the cocktail shaker. [step] Stir the absinthe mixture well with a cocktail spoon.

Ex Input:
[header] How to swat a fly without a fly swatter [title] Slap the fly with one hand. [step] Swat a fly by trapping it between one hand and a hard, flat surface that you have gotten it to land on. Move slowly toward the fly, then slap it quickly and firmly with your hand. <sep> (A) A very light slap like this works well to send the fly flying, but even a smack would work very well depending on the fly's size. [substeps] Using a fly swatter should be enough to remove the fly fly from your hand. (B) The movement of your slap will force it to land on the floor, suggesting that you are probably right for it. [substeps] If the fly lands on the ground instead of a tough surface, you've caught it mid-flight or might have hit it again. (C) [substeps] Approach the fly very slowly until you are within an arm's length of it. Keep your arm still until you are in position, then move it as quickly as possible in one motion toward the fly to hit it. (D) Repeat this until the fly lands quickly and you can swat any fly quickly. You may not get to swat very easily, but most people do.
