Prepare the guajillo chile peppers: With scissors, cut off the stems off the peppers. Cut them open, then remove and discard the seeds and veins. Place the peppers in a bowl and cover them with the boiling water. Cover the bowl and let the chile peppers soak while you do the rest.
Place the halved limes on the table where all can reach them, so that each person can squeeze the juice to taste into their flavorful bowls of Mexican shrimp soup. Provide saltines or other crackers or tostadas, if desired, for a wonderful texture complement.
