01 - Combine ube halaya, ube extract, sweetened condensed milk, whole milk, salt, and vanilla extract in a blender or large mixing bowl. Blend or whisk until completely smooth and well incorporated.
02 - In a chilled bowl, beat the cold heavy cream using an electric mixer until stiff peaks form. Do not overwhip.
03 - Gently fold the ube mixture into the whipped cream using a spatula. Incorporate carefully until the color is uniform and no streaks remain, taking care not to deflate the cream.
04 - Pour the ice cream base into a loaf pan or freezer-safe container. Smooth the surface evenly with a spatula.
05 - Cover tightly with plastic wrap or a lid. Freeze for 6 to 8 hours, or until the ice cream reaches a firm, scoopable consistency.
06 - Remove from freezer and let stand at room temperature for 5 minutes before scooping to achieve optimal texture.
