Stir in the pickling lime being careful not to breathe it in.
Stir in the corn and simmer for 40 minutes. Tip of corn will have darkened in color relative to dried corn ( shown on left ) . Exterior of corn will be softened enough to cut through, but interior will still be bright white, starchy and hard (al dente). Simmering may take longer for harder corns such a popcorn.
Take pot off heat and let the corn soak for at least 8 hours and up to 24 hours at your convenience.
Place pot in sink and use your hands to transfer nixtamalized corn to empty bowl, leaving sludgy water in pot.
Fill bowl with fresh water and rub corn for a few minutes until thin clear outer shell comes off the corn. Water will be very cloudy.
Carefully pour water out of bowl and refill with water 4 or 5 times, rubbing corn some more each time, until water is completely clear.
Hominy stage
Return corn to cleaned stainless steel pot.
Add 1 liter of water - water level should be about 1 inch above corn.
Add salt to taste if you intend to use on its own as a side dish.
Bring to a boil and then simmer for about an hour until corn is puffed up and tender through and through (cross section of corn, shown on left in picture is no longer bright white). It will have more than doubled in size (center of picture) compared to its dried form (shown on right).
Enjoy as a tasty side dish and substitute for rice or other starch in your recipes.
Freeze what you don't expect to use within 5 days.
