Separate the 5 garlic bulbs into cloves, make sure that you remove the external rough skin of the bulb but that you keep the cloves’ skin.
Put the garlic cloves in a saucepan full of cold water. Put the saucepan on your stove at high heat. Bring to the boil and let it boil for 2 minutes. Drain. Rinse the cloves under fresh water. Repeat this 4 times (5 if the cloves are big) each time starting the boil with cold water.
Remove the skin, mix, add salt and pepper and mix again.
You can add some milk if you wish to have a softer texture.
Notes
The main steps: Separate garlic bulbs in cloves, boil them 5 times, remove the skin and mix.
