Okay, I can now attest to the Power of Ratios™ in cooking. Knowing the basic ratio of cookie dough (1 part sugar, 2 parts fat, 3 parts flour), and then added cocoa powder and chocolate chips, I’ve got some damned good chocolate chocolate chip cookies.

That kind of explains my success in taking the recipe on the back of the chocolate-chip bag and cutting the sugar in half.
