Rich, creamy and smooth with notes of butter, brown sugar, and vanilla, this Homemade Butterscotch Sauce was originally published in the Teena in the Kitchen Cookbook, published in 1954. Just goes to show that the best recipes stand the test of time.
In a medium saucepan, mix brown sugar, corn syrup, water, butter, and salt together. Over medium heat, bring the mixture to a boil, do not stir, and let it cook until it reaches 236°F (soft ball stage).
Remove from heat and cool mixture to lukewarm.
Stir in cream and vanilla.
Pour into a heatproof jar and store in the refrigerator. Use within one month.
To reheat before serving, pour into saucepan and warm over low heat; or set jar in a small pot of simmering water.
