Homemade Caramels..mmmm

Yesterday I got a craving for caramels but couldn't find anything that looked good at the store. So I decided to make my own. The first batch turned out ok-- the flavor is great, but its too soft (I should have cooked it longer/hotter). Then my mother in law heard about my efforts and gave me her grandmother and great-aunt's recipe. Tomorrow I'm going to go to the grocery store and get the ingredients to try again. 

Great Grandma's English Caramels
