Lime Bars

One of the things left over from my birthday party was a giant bag of limes, and I have been thinking that I need to make something with them.  I just bought a new dessert cookbook from William Sonoma which has a recipe for Key Lime Bars (I used regular limes in stead of key limes).  I can't find a similar recipe online because they all use sweetened condensed milk, and this one called for eggs, sugar, lime zest, lime juice, sour cream and a little flour.  But either way I don't think you can go wrong with graham cracker crust and a citrusy, sugary, custardy filling.  Joy!
