Steep the tea: Add chai tea bags to ½ cup hot water. Steep 5-7 minutes until dark and concentrated. Remove tea bags and let cool to room temperature.
4 chai tea bags, ½ cup hot water
Blend the base: Add cooled tea, half and half, cottage cheese, sweetened condensed milk, vanilla extract, salt, and cinnamon to a blender. Blend on high for 30 seconds until completely smooth.
1 cup half and half, ½ cup cottage cheese, ½ cup sweetened condensed milk, ½ teaspoon vanilla extract, ¼ teaspoon salt, ¼ teaspoon ground cinnamon
Freeze: Pour into Ninja Creami pint container (don't exceed max fill line). Freeze on a flat surface for 24 hours.
Spin: Remove pint from freezer. Take off lid and place in outer bowl. Attach paddle lid and select **Ice Cream**.
Check texture: If crumbly or powdery (normal for tea-based ice cream), make a small well in the center and add 1-2 tablespoons half and half or milk. Select **Respin**.
Serve: Scoop immediately for soft-serve texture, or freeze 20-30 minutes for firmer scoops.
Notes
Steep the tea properly - 5-7 minutes. Set a timer. This makes or breaks the flavor.
Let the tea cool completely - Hot tea will curdle the cottage cheese. Room temperature is what you want.
Use full-fat cottage cheese - Low-fat won't blend as smoothly or taste as creamy.
Taste before freezing - The base should taste slightly sweeter and more intensely flavored than you want. Freezing dulls both.
Expect to respin once - Tea-based ice cream almost always needs it. Don't worry when it looks crumbly first.
Freeze on a flat surface - Uneven freezing = uneven texture.
Don't skip the cinnamon - It really does boost the chai flavor and round everything out.
Use what you have - I've tested this with three different chai tea brands. They all worked. Don't overthink it.
