Standard home blenders often struggle to pulverize ice cream uniformly with dairy liquids without leaving fat streaks. Using a high-powered jar running at high speed for precisely 45 seconds ensures the instant coffee granules dissolve completely without overheating the liquid mixture. Cold dairy proteins trap air efficiently during high-speed agitation, creating the necessary foam structure.
Condensed milk introduces sucrose and lactose alongside reduced water content, which alters the freezing point and thickens the body far more than liquid sugar can. When combined with the fats in vanilla or chocolate ice cream, this concentrated dairy solids ratio coats the palate slower, prolonging the perceived bitterness of the coffee.
Blended dairy beverages containing ice cream do not store well in the refrigerator beyond two hours because the air incorporation rapidly collapses. Pouring leftover mixture into ice cube trays allows for up to seven days of freezer storage before noticeable oxidation alters the milk solids.
