Crock Pot Method
Sweetened Condensed Milk
Heavy Cream; for thinning if desired
If you are cooking in the can, remove the label and put a towel underneath the can(s) to prevent rust stains in your slow cooker. (Do NOT open the can until after it's cooked.)
If using mason jars, pour condensed milk into the jar(s) top with lid(s) & and tightly close with canning ring(s).
Fill crock pot completely with water; enough to cover the top of the can(s) or jar(s).
Cover crock pot with the lid and cook on low for 8 hours or until preferred caramelization is achieved. (Mine turned to caramel right at the end in the 8th hour, so don't freak out if it looks white for a really long time.)
If you are using Homemade Sweetened Condensed Milk, it may look foamy on top once you've opened the lid & that's ok. Stir it up while it's hot because it will smooth out. Also, you can add heavy cream, 1 TBSP at a time, to thin the caramel for drizzling purposes or if it is too thick for your liking.
After cooling, refrigerate up to two weeks.
Stove Top Method 1
Pour the condensed milk into a saucepan.
Put it on medium-low heat, stirring continuously. (for 10-15 minutes)
Take off the heat when it is caramel in color and you can turn a cooled tablespoon of it upside down without it falling off.
Stove Top Method 2
Immerse closed unopened can on its side in a pot of water and bring to a boil.
Leave on a simmer or light boil for 2 to 2 and a half hours, topping up with water as needed. Be careful and don’t let the water dry out or the can could explode.
Remove from heat and let cool thoroughly before opening can. Don’t open the can while its still hot. The condensed milk should be thick and a nice caramel color.
Stove Top Method 3 Bulking
Two parts condensed milk to one part sugar and one part butter.
Melt equal weights of brown sugar and butter in a pan and simmer on a low heat until the two become a smooth liquid.
Add condensed milk and raise the temperature very gently until it starts to simmer. Keep the temperature low and stir continuously until brown. This should take around 20 minutes.
