In a small mixing bowl, whisk together garlic, vinegar, and salt. Sit for at least 20 minutes.
Briskly whisk in olive oil, followed by the cream. Taste and adjust for salt and acid as needed.
Dressing should have a distinctive garlic bite that will balance out when combined with other ingredients. Dressing will keep refrigerated for up to 3 days.
Salad
In a large mixing bowl, add all of the shredded cabbage and apply enough of the dressing to coat very well. Don’t be shy with the vinaigrette!
Divide the cabbage among 4 chilled plates.
Sprinkle the copped olives and pistachios around each of the salads and grate Mahón cheese over the top. Finish with a sprinkle of parsley.
