Recipe: Sweetened Lime Juice

I saw this recipe on eGullet's Spirits & Cocktails forum (how's that for some linkage?!). I happen to have some beautiful fresh limes on hand... I may have to try this:

Take a clean soda bottle (8oz is fine). Fill it half-way with sugar.
Fill the other half with water. Cap. Shake well. Let settle.
This takes 5 minutes.
Shake 2 more times until syrup is clear.

Zest of 1 lime, and add that to the bottled syrup. Save lime.
Cap, and give a light shake. Put directly into fridge.

Do not cut lime until the next day.

Next day, strain lime syrup, and then put back into bottle.
Juice lime.
Add lime syrup to taste.

I would interpret this recipe as:

Ingredients

• 1 cup simple syrup (cooked or shaken)
• Zest of 1 lime
• Juice of 1 lime

Method

1. Steep zest in simple syrup overnight, in fridge.
2. Strain resulting lime syrup and re-bottle.
3. As needed, add lime syrup, to taste, to fresh lime juice for exceptional sweetened lime juice.

I want to try this in a cosmo, to see how the flavors differentiate.
