If feeding into a clean jar, always add water first, then sourdough starter then flour. This will enable you to mix it together more easily and you won't have such a mess.
Once you've discarded, add water to your jar, screw on the lid and shake to mix the water and starter, then add the flour. Your starter will love this! Watch it grow!
