Make the garlic sauce: Add the garlic and salt to a food processor and process until completely smooth, scraping down the sides of the bowl as needed.
2. Step
With the processor running, slowly pour in ½ cup (120 ml) of olive oil and continue to process until smooth and creamy. The mixture should begin to thicken as the oil emulsifies with the garlic.
3. Step
Pour in 2 tablespoons of lemon juice, while continuing to process, so that the lemon juice incorporates completely and the mixture does not separate.
4. Step
Add the remaining olive oil and 2 tablespoons lemon juice and process until very smooth. Transfer the sauce to a small bowl.
5. Step
Serve the fries with the garlic sauce and sprinkle with parsley.
