Experimenting with @runpunkrun's lemon bars

Over on the gluten_free community, I posted Experimenting with @runpunkrun's lemon bars, a detailed discussion of my baking experiments.

Things I have learned while experimenting with this recipe:

• I am an engineer, not a scientist. Obviously I should have changed one thing at a time and held everything else constant until I achieved what I wanted. What I did is use available ingredients and eyeball quantities and see how it turned out. At least I took some notes!
  
• My intuition about what to change works a lot better for the filling than the crust.
  
• The kind of oil matters.
  
• The kind of citrus matters.
  
• Buy an extra lemon. Not all lemons are equally juicy.
  
• My cat likes lemon bars. Who would have thought! I left a full pan cooling on the counter, and when I came back the top looked different... like it had been... licked???
