This is a recipe video for a professional-grade no-bake cheesecake that achieves the ultimate melt-in-your-mouth texture without the need for gelatin. The base is made with crushed biscuits and melted butter, and cream cheese that has been warmed in the microwave and brought to room temperature is mixed with yogurt, granulated sugar, and lemon juice. The heavy cream used is 42% milk fat, and the key is to whip it firmly while cooling it in ice water. Mix all the ingredients together, pour into a mold, and chill in the refrigerator for at least 4 hours to set. It is a visually appealing treat with a fluffy, creamy texture and refreshing tanginess.
