Place the cottage cheese, fresh lemon juice, lemon zest, and maple syrup in a blender.
Blend until the ingredients form a completely smooth and evenly combined mixture.
If the mixture is too thick for the blender to process efficiently, add 1 tablespoon of the milk and continue blending until smooth.
Transfer the blended cottage cheese mixture evenly into an ice cube tray.
Place the tray in the freezer and leave it there until the mixture has frozen completely into solid cubes.
When ready to prepare the ice cream, remove the frozen cubes from the tray and place them in the blender.
Add only enough of the remaining milk to allow the blender blades to move freely.
Blend until the frozen mixture becomes creamy and smooth.
For a thicker, scoopable ice cream, use only a small amount of milk during the final blending stage.
Transfer the creamy mixture to a bowl once it reaches the desired scoopable consistency.
For a softer, soft-serve-style texture, gradually incorporate additional milk while blending until the mixture becomes lighter and softer.
For a firmer ice cream texture, spoon the blended mixture into an airtight container and freeze for an additional 1–2 hours.
If the ice cream becomes excessively firm after freezing, leave it at room temperature for approximately 15–20 minutes before serving.
