Since then, the internet has been dying to know exactly what is in that secret recipe.
Then last night, Olivia shared a snap to her Instagram story of a recipe from Nora Ephron’s book Heartburn (which, tellingly, is about divorce) revealing the secret ingredients.
So we simply had to try making it.
The recipe calls for fairly simple ingredients: “Mix 2 tablespoons Grey Poupon mustard with 2 tablespoons good red wine vinegar. Then, whisking constantly with a fork, slowly add 6 tablespoons of olive oil, until the vinaigrette is thick and creamy; this makes a very strong vinaigrette that’s perfect for salad greens like arugula and watercress and endive.”
What on earth is Grey Poupon mustard, you may ask? Yeah, we couldn’t find it either, so we replaced it with the classic Dijon mustard. (Upon reflection, this may have been a mistake - you’ll see why).
We chose a simple bag of mesclun lettuce for our salad, mixed the dressing ingredients together, and unleashed the Olivia Wilde salad upon our unsuspecting colleagues.
Watch the video above to see what they thought.
The verdict:
Lifestyle & Entertainment editor Jenni said the dressing was “fine”. Front Page podcast host and secret foodie Damien said it was not worthy to sit alongside a steak. Our cameraman Cam declared it tasted like Big Mac Sauce. Not exactly glowing reviews.
But don’t take their word for it - here’s the recipe so you can try it for yourself.
