Wait, don't dump that milk! It may have a slightly sour smell and be expiring tomorrow, but you can still put it to good use by making sour milk jam.
Sour milk jam is made by cooking down the expiring milk with sugar and then adding crème fraîche. The pleasantly sour flavor of the crème fraîche will overcome the potentially unpleasant flavor of the milk to create a dessert topping that is as delicious as it is unusual.
Please note that if your milk was purchased from the grocery store (meaning it was ultra-pasteurized) and is way past the date (use your nose to judge how far gone it is) on the bottle or carton, you should not use it—even for this preparation.
Condensed Milk vs. Sour Milk Jam
Condensed milk is a combination of milk and sugar. According to Serious Eats, condensed milk is reduced to 60% of its original volume. The texture of condensed milk is thinner than cream but thick enough to coat a spoon. It is syrupy and very sweet, and commonly enjoyed in coffee or drizzled over desserts.Sour milk jam, on the other hand, is not as sweet as condensed milk. The sour flavor of the crème fraîche complements the caramelized sugars in the milk, but neither the sweetness nor the sourness is overpowering. Sour milk jam is also thicker in texture than condensed milk. After refrigeration, the sour milk jam turns into more of a spreadable consistency, while condensed milk remains thin and pourable.
Dulce De Leche vs. Sour Milk Jam
It is easy to tell dulce de leche and sour milk jam apart by their color alone. Dulce de leche has a deep caramel color and may even be mistaken for caramel itself. This is because dulce de leche is composed of milk and sugar cooked down slowly until the sugars are completely caramelized. The texture of dulce de leche is thick and gooey, so it makes a great topping for rich and creamy desserts like ice cream.Sour milk jam is white because it has very little caramelized sugar. Sour milk jam may thicken slightly in the fridge, but it never becomes sticky nor gooey. It is also much more mellow in its sweetness than dulce de leche. Sour milk jam adds a light, creamy sweetness atop ice cream, but it also pairs well with a simple cup of fruit.
