Using a fork, crush garlic and coarse salt together in a small bowl until mixture is soft and moist, interspersed with large chunks of garlic. Gradually drizzle in olive oil while mixing vigorously with a fork. Add a generous sprinkling of pepper and continue to mix.

Whisk in lemon juice to make a smooth dressing. Strain dressing through a fine sieve, discard solids, and adjust the seasonings. Store in the refrigerator for up to 7 days.
