Rinse and thoroughly dry the coriander leaves. Remove most of the stems. Chop the leaves coarsely.
Peel and chop the garlic coarsely.
Rinse and dry the peppers. Chop coarsely.
Place the coriander, garlic and peppers in the food processor and process on high for several minutes to obtain a chunky paste.
Add salt, pepper (and cumin for red schug) and process again to incorporate.
Stop the processor and stir the olive oil in by hand. For the green schug, pour the lemon juice over the surface before putting it away. This will help preserve the green color.
