The Jig. The Jig is almost as important as ice if you ask me. A jig is used to perfect the art of making an awesome cocktail consistently. This thing is a two headed jig, one side has indentations for 1/2 ounce the second measurement is an ounce if you fill it to the top. The second side has and indentation that indicates one ounce, the second indentation is for an ounce and a half, the last measurement is my favorite it's 2 ounces to the top — cause that's how big papa makes the drinks for the people ; )
