Heat the Milk: Pour 2 liters of whole milk into a saucepan and heat on high, stirring occasionally to prevent curdling. Wait until bubbles form on the surface.
Add Vinegar and Curdle: Reduce heat to low and add 1/4 cup white vinegar. Stir gently as the milk curdles and separates into curds and whey. Continue stirring gently until the whey becomes clear.
Strain the Curds: Turn off the heat. Using a strainer, lift the curds and press gently to remove excess moisture. Leave to cool at room temperature, then cover and refrigerate.
Whip the Cream: In a separate bowl, whip half a box (237 ml) of heavy cream until fully stiff.
Combine Curds and Whipped Cream: Crush the curds and fold them manually with the whipped cream using a spoon until a homogeneous, airy, and smooth cream forms. Avoid using an electric mixer to maintain texture.
Chill the Cream: Cover the cream and refrigerate for at least 4 hours or overnight before using in cold desserts.
Serving Suggestions: Use this cream in cold desserts such as qatayef, warbat, halawat al-jibn, and rice desserts. Do not use in baked desserts as the cream may melt and lose consistency.
