Wow I got this from a friends post, I did not know this!!!!
"Been doing this for years! My mother taught it to me! Unopened can of
sweetened condensed milk + 8 hours on low (completely submerged in
water) in the crock pot + cool down in the fridge = Caramel! This is the
best caramel I've ever had, let alone made! It's so easy! Need to try
this! — 3 hours on the stovetop!"
