Cookie success

...hard on the heels of much cookie non-success.  I've figured out the key to edible baked goods: measuring.  Follow the recipe.  It's not like sewing, it turns out.

My baking goes in a cycle- I measure meticulously for a while, and make great baked goods.  My confidence builds, I start to throw in experimental additions and substitutions, things get wild; quality declines.  Eventually I have a couple disasters, the kind that make me feel like I should have just dumped a bunch of flour and sugar in the garbage and saved the interim steps.  Then I go back to following recipes.  Repeat.

I'm back on the top of the quality cycle now, with this recipe.  Tahini cookie success.  Cookie quality is measured in hours, after all- how many hours the cookies last.
