Add 1 teaspoon (4 g) of sugar and 1/2 cup (120 ml) of cold water. Put the lid on the blender or processor. You could substitute your favorite low-calorie or natural sweetener for the sugar. Blitz the guava mixture just until the guava is smooth and mixed with the water. Avoid blending the mixture for too long or the seeds will become finely ground. This will make it difficult to strain them out and your guava juice will be gritty. Set a fine mesh strainer over a bowl. For even smoother juice, line the strainer with cheesecloth. Scoop the guava mixture into the strainer and use a spoon to gently push the mixture through it. You can discard the tiny, hard seeds that are left in the strainer. Place several ice cubes into 2 small serving glasses. Pour the strained guava juice into the glasses and serve it immediately.
Summary: Peel and chop the guavas. Measure the ingredients into a blender. Blend the guava mixture. Strain the guava juice. Add ice cubes and serve the guava juice.
