Add in 24 ounces evaporated milk very, very slowly, whisking/stirring constantly while boiling. Make sure the addition of the milk isn’t slowing the boil. This should take about 20 minutes.

Lower to medium-low heat and attach a candy thermometer, heat stirring often until mixture reaches 238°F. Remove from heat immediately and pour into the prepared pan.
Allow to cool on the counter for 4 to 5 hours.
Wet a sharp knife with cold water, and slice caramels into 10 rows across, then 8 rows lengthwise (or desired size/shape).
Wrap with wax paper squares or pre-cut candy wrappers.
Notes
Make sure you are using a heavy-bottomed pan. Thin pots tend to heat unevenly and may not give you the desired results.
The temperature is key when making caramels. Make sure you are using a candy thermometer so that you can be precise.
If you’re having difficulty cutting the caramels, you can throw them in the freezer for about 15 minutes to harden them up and make them easier to work with.
