Add in the water, the piece of ginger, black lentils, cherry tomatoes, jalapeno, soy sauce, sherry, salt, pepper, and paprika. Cover the pot and bring to a boil. Lower the flame and allow to simmer for at least 30 minutes. The longer it simmers, the more the tastes will become strong and the black lentils will absorb. They do not absorb like dried lentils do, only just a little.
