There are a few things to keep in mind when preparing herbs for use in soup. Here's a step-by-step guide on how to prepare herbs for use in soup: 1) Start by Wash the herbs thoroughly under running water. This will remove any dirt or debris from the leaves. 2) Next, using a sharp knife, chop the herbs as finely as possible. The smaller the pieces, the more flavor they will release into the soup. 3) Finally, add the chopped herbs to the soup during the last few minutes of cooking so they don't lose their flavor.
