In a blender shear the water and agar agar. Bring the mixture to a boil and add the sugar and salt to dissolve. Remove from the heat and whisk in the yuzu juice. Pour into a shallow container and refrigerate until set. Transfer to a blender and blend thoroughly until a smooth puree is achieved. Strain through a fine chinois.
