Prepare a cup of raspberries. Wash them and dab the water out.
Roughly blend the raspberries with a blender. Don't blend it fine; otherwise, it will blend the seeds and make it bitter.
Pour the raspberry blend into the strainer. Press the raspberry pulp through the mash using a spatula or the back of a spoon. Move the spatula or spoon in a circular motion to help push the juice and pulp through while leaving the seeds behind.
Take 1/2 cup of raspberry purée and 1/8 cup of oats. Mix 1/3 cup of sugar of your choice with the raspberry purée. Add a tablespoon of lemon juice and 1/4 teaspoon of salt.
Blend all of it again with a blender. Pour the mixture into the pint. Place the storage lid on a pint and freeze for 24 hours.
Remove the pint from the freezer and remove the lid from the pint. Place the pint into the Ninja Creami Ice Cream Maker.
Select GELATO. Run the program.
When processing is complete, remove the gelato from the pint.
Serve immediately. Buon appetito!
