Separate garlic cloves and peel them. Shaking the cloves vigorously in a closed jar helps loosen the skin and makes peeling much easier.
Process in a small food chopper until the garlic is the desired consistency.
Add lemon juice and salt to the minced garlic and gently mix with a spoon.
Fill an appropriately sized jar with the garlic mixture.
Fill with olive oil until it just covers the minced garlic.
