4 servings
1 can sweetened condensed milk (regular size)
1/2 cup crushed graham crackers
3 regular limes (or 5-6 key limes)
1/4 cup butter

1) Zest the limes, put 3/4 of zest in bowl.
2) Slice the limes in half or quarters and squeeze juice into the same bowl.
3) Open can of condensed milk and mix with lime juice and zest. Let stand.
4) Heat a fry pan and melt butter. Mix with graham crackers. Scoop into an 8" fry pan and with a fork pat it down flat covering the base.
5) Pour contents of bowl (condensed milk, lime juice, and zest) on top.
6) Sprinkle the balance of the zest on top.
7) Cover and let sit 20 minutes. No cooking. This process firms it up.
8) Serve

As you may have noticed I had a "can" in the recipe. Anyone ever see condensed milk in anything other than a can? Any ideas to transfer to different containers and remain safe?

This is really fun and simpler than you think. Try it at home and you'll be surprised. It's a fun treat on a long trip.
