In a medium sauce pan combine water, sugar, and salt; bring to a boil over medium heat stirring occasionally until sugar has dissolved and comes to a boil. Continue to cook over medium heat until sugar mixture is light amber in colour, swirl pot occasionally during this stage. Do not stir (approx. 20 minutes).
Remove from heat and add cream, butter and vanilla (mixture will bubble and double in size then settle). Once mixture begins to settle, stir just until combined.
Use in Salted Caramel Apple Pie or as a topping for your favorite dessert. Mixture can be refrigerated for up 2 weeks in an air tight container.
Tips & Variations
To prevent crystalization of sugar- avoid stirring the sugar once it begins to boil in the initial stage. Use a pastry brush with water and brush sides of pot where sugar is accumulating.
