If I am making a mixed drink, what does 2 cl mean?!
Answers: It says 2 cl amaretto, 2 cl baileys, and 2 cl kahlua
The person that told you centiliters is correct, and the person that told you it doesn't matter is also correct. When making drinks most recipes will tell you parts rather than an actual measurement. So in other words the recipe you listed should look like this.
1 part amaretto, 1 part baileys and 1 part Kahlua.
A part can be anything you want it to be, an ounce, a cup, a liter or a gallon.
cl = centiliter
1 oz is about 3 cl
Actually, it doesn't matter if all measurements are the same; it's just equal parts amaretto, irish cream and kahlua. Use a shot glass or tablespoon or whatever you want to measure the three parts.
2cl = 20ml = 1tablespoon + 1teaspoon
