Mix garlic and salt together in a metal pot.

In a separate pot, heat olive oil near the smoke point (~230°). Carefully pour olive oil over the garlic and salt a little at a time while constantly stirring.

Once oil has settled but is still hot, add in the red pepper flakes and stir to combine.

Allow oil mixture to cool to room temp.

Then pour oil mixture into a serving bowl and top with feta cheese, and squeeze in juice from a fresh lemon slice. Serve with toasted French bread.
