In a large bowl, thoroughly mix together the condensed milk, vanilla extract and the coconut.
In a medium bowl, beat the egg whites using a hand-held electric beater, till stiff peaks form, for about three to four minutes.
Using a spatula, gently fold in the beaten egg whites into the coconut mixture, being careful not to overmix.
Lastly sprinkle the salt grains on the mix lightly blend in with the spatula.
With moistened hands, form small balls of about 1 ½ inches diameter and place on the baking sheets, 1 inch apart, giving the macaroons space to expand while baking.
Bake in the preheated oven, for about 22 to 25 minutes, till the top of the macaroons start to brown.
Transfer to a cooling rack and they are ready to go!
Note: These can be stored in an airtight container in the refrigerator for three weeks, that is, if they last that long!
