Name: Lime-Oregano Vinaigrette (Vinagreta de Oregano)
Prep time: 10 min
Total time: 10 min
Yield: About 1 cup
Cuisine: Mexican
Ingredients: 2 teaspoons dried Mexican oregano; 1 small garlic clove; 1 teaspoon kosher salt, plus more to taste; 1/4 teaspoon freshly ground black pepper; 1/4 cup fresh Mexican lime juice, from 5 to 6 small limes; 2 tablespoons white vinegar or mild cane vinegar; 1 teaspoon agave syrup or piloncillo syrup, optional; 1/2 cup mild olive oil or neutral vegetable oil

Question 1

Can I use Italian oregano instead of Mexican oregano in this vinaigrette?

Accepted Answer

Use dried Mexican oregano for lime-oregano vinaigrette because it tastes citrusy, resinous, and slightly bitter. Italian oregano is softer and sweeter, so it makes the dressing taste flat. Crush dried Mexican oregano between your palms into flakes before mixing, not dusty powder.

Question 2

Why do I let Mexican oregano sit in lime juice before adding oil?

Accepted Answer

Let crushed Mexican oregano sit in fresh lime juice, vinegar, garlic-salt paste, and black pepper for 3 minutes before adding oil. The acid softens the oregano flakes and pulls their flavor into the liquid before the oil coats the herbs and slows extraction.

Question 3

How do I emulsify lime-oregano vinaigrette?

Accepted Answer

Pour mild olive oil or neutral vegetable oil into the lime-vinegar mixture in a thin stream while beating with a fork or small whisk. The lime-oregano vinaigrette should turn cloudy and lightly thickened, with oregano suspended through the dressing. In a jar, shake hard for 20 seconds.

Question 4

What should I serve with vinagreta de oregano?

Accepted Answer

Serve vinagreta de oregano over warm grilled nopales, market tomato salad, cucumber, or carne asada from the comal. Taste the dressing with cooked nopal, cucumber, or grilled beef instead of from a spoon so the salt, acid, herbs, and oil balance against real food.

Question 5

How do I fix lime-oregano vinaigrette if it tastes too sharp or too heavy?

Accepted Answer

If lime-oregano vinaigrette tastes too sharp because the vinegar is harsh, add 1 teaspoon agave syrup or piloncillo syrup to round the edge without making it sweet. If the dressing feels heavy, add a few more drops of fresh Mexican lime juice.

Question 6

How long does lime-oregano vinaigrette last in the refrigerator?

Accepted Answer

Lime-oregano vinaigrette keeps for up to 3 days in the refrigerator in a sealed jar. Shake hard before serving because the oil and acid separate naturally. For the brightest flavor, add an extra pinch of crushed dried Mexican oregano just before serving.
