Place the oats, water, cinnamon, cloves, sugar and salt in a large pot and bring to a boil on medium heat.

Add the milk, bring to a boil once more on medium heat. Cover, lower heat to low and simmer for about 10-15 minutes.

Pour the oatmeal mixture into a jar or container, let it cool completely, cover and refrigerate for at least 3 hours.

Strain the mixture through a sieve to remove the cinnamon sticks and whole cloves, place the mixture in a blender and blend for a few minutes until you get a smooth consistency. Taste the oatmeal to see if it needs more sugar, you can also add more milk if you want it to have a thinner consistency.

Serve cold.
