► Chop or mince the garlic cloves into the size you want them.
► Transfer the chopped or minced garlic into a small bowl and add some Extra Virgin olive oil. Mix the garlic and add more oil until all the garlic pieces are coated with oil and appear shiny.
► Place the minced garlic into a bowl. Add a small amount of olive, or any other kind of oil, and stir to combine. Keep adding extra oil until all the garlic is shiny and lightly, but thoroughly coated with oil.

Then press down firmly on each portion with the back of a spoon to exclude air bubbles and ensure an even size for the portions. Add extra oiled garlic as required until each compartment and container is packed full to the top with garlic.
