In a heavy 2-quart saucepan over high heat, combine the jalapenos, peppers, sugar and vinegar and bring to a boil. Reduce heat to medium and simmer for 20 minutes, stirring every 5 minutes. Be careful not to let the mixture boil over. Turn off the heat and add the pectin slowly, mixing well. Turn the heat on again to high and cook until the mixture comes back to a boil. Let cool. Separate individual ribs and serve.
