Step 4: Add optional flavorings
Remove the pan from the heat. Stir in the optional butter, vanilla extract, and pinch of salt until evenly combined. The butter adds richness, while vanilla gives the condensed milk a dessert-like aroma.
Step 5: Cool and store
Let the mixture cool briefly, then transfer it to a clean container. Refrigerate promptly. It will thicken further as it cools, so do not over-reduce it while hot.
