This was the easiest thing to make and quite surprising to me. Buy three 14 ounce cans of sweetened condensed milk (organic is available for about a buck more). Pierce each tin once with a can opener. It's the kind of can opener we used to open can's of juice with when we were kids, now everything is twist off , so it made this seem like an old fashioned thing to do.
Cover the tops of the tins with tin foil, get as tight a seal as you can and place the tins in a heavy bottomed pot of hot water and bring to a rolling boil. The water should come up to within an inch of the top of the tins. The tins may bounce a bit, the water may get a little milky and even developer a scum. Water may spil onto the top of the tins: Not to worry.
Fill the pot with more hot water when ever it starts to get low. Do this for 4 hours. Yes it is a time commitment, but worth it! You need to be checking in every 20 minutes or so.
When the 4 hours are up turn off the heat, with tongues carefully remove the tins, discar the tin foil and let sit until they have cooled enough to be able to handle comfortably: 10-15 minutes.
date nut bars into it.
date nut bars were pretty awesome. And if you got the link you'll notice that the bars there are just called Date Bars, I felt with the heaping cup of pecans that I added that the nuts should get equal billing.
