Place the cornmeal in a medium size pot.
Add the oil and salt and stir well, until all the grains are well coated.
Pour in the water and bring to a boil over high heat, stirring occasionally.
When a boil is reached, move to your lowest heat (you want the grains to steam).
Cover the pot and cook for 10-14 minutes, until the grains on the top of the pot feel dry to the touch (if the feel wet steam for a further 3-5 minutes).
Remove from the heat and allow to rest for 30 minutes or until cool enough to handle.
Move to a large bowl, stir to brake the mixture into small lumps.
Place the lumps in a food processor and pulse3-4 times until aerated and separated to individual grains. Alternatively, run the lumps trough a couscous sieve to separate them to individual grains.
Now you have couscous!!!
The prepared couscous keeps refrigerated 3-4 days and can be frozen (see notes)
Place the cornmeal, oil and salt in a microwave safe dish with a tight-fitting lid. Stir well.
Add the water, stir and close the lid.
Microwave on high for 5-7 minutes.
Take out the dish, remove the lid (carefully! hot steam)), stir well, cover and microwave for 5 more minutes.
Allow to cool, for 30 minutes or until cool enough to handle, then aerated as mentioned above.
