Things You’ll Need:
- Two heads of garlic
- 7 Yukon gold potatoes
- 1/2 cup extra virgin olive oil
- 1/2 cup pure olive oil
- 1/3 cup tarragon vinegar
- Salt
- Freshly ground black pepper
- Food processor
Step1
Pre-heat the oven to 350-degrees F. Place 2 unpeeled heads of garlic on a baking sheet, sprinkle with some of the olive oil, cover with foil and bake 45 minutes. Remove from the oven, let rest about 10 minutes and then squeeze the garlic until the pulp comes out. Reserve the pulp in a small bowl.
Step2
Peel 7 Yukon gold potatoes and boil in salted water till tender. Drain and place in a large mixing bowl. Use a fork to mash the potatoes slightly. Sprinkle again with salt. Immediately add the garlic pulp and blend.
Step3
Combine the extra virgin and pure olive oils. Place about 1 cup of the potato-garlic mixture in the food processor. Cover the processor and pulse the mixture on and off while adding 1/4 cup of the mixed oils in a steady stream.
Step4
Continue pulsing while adding several tbsp. of vinegar. Transfer the mixture to a large bowl. Repeat the pulsing in the food processor until all of the potato-garlic mixture, the oils and the vinegar have been used.
Step5
Add salt and pepper. Mix again by hand and allow the sauce to cool uncovered for 30 minutes. Then cover tightly with plastic wrap and refrigerate at least 4 hours. Intermittently, change the plastic wrap if condensation forms. Serve cold.
