Boil ears of corn 5 minutes. Dip in cold water. Cut whole
kernels from cob or use packages of frozen corn. Combine
peppers, celery, onions, sugar, vinegar, salt, and celery seed
in a saucepan. Bring to a boil and simmer 5 minutes, stirring
occasionally. Mix mustard and turmeric in 1/2 cup of the
simmered mixture. Add this mixture and corn to the hot mixture.
Simmer another 5 minutes. If desired, thicken mixture with flour
paste (1/4 cup flour blended in 1/4 cup water) and stir frequently.
Fill half pint or pint jars with the mixture, leaving 1/2 inch headspace.
Adjust lids and process for 15 minutes in a boiling water canner.
