How to make Pisco Sour

There are lot of recipes on the Net, but the way I make it:

1. I use shaker, the portion is for ~4 cups.

2. Put some ice cubes into shaker.

3. Pour one part of pisco, one part of fresh pressed lime juice, half part of egg white and some jaraba de goma (sugar syrup). If I don’t have the syrup, I just give teaspoon or two of sugar.

4. Shake really well, until ice breaks in very small pieces and there is nice foam on top.

5. Pour in the glasses, give few drops of Angostura bitter. Disfruta!

Actually I don’t give exact proportions and use rule of thumb. Taste if it’s good, and if not, give some more pisco or juice or sugar.
It’s important to use limes, not lemon. It tastes better.
