Ingredients Method Notes

Ingredients
  

Creamy Base
  • 1 head of garlic (whole, unpeeled)
  • 120 g plain Greek yogurt full-fat or 2%
  • 60 g mayonnaise
Brightness & Finish
  • 15 ml fresh lemon juice
  • 15 ml extra-virgin olive oil
  • 3 g salt or to taste
  • Freshly ground black pepper to taste
  • Optional: 5g fresh herbs — chives parsley, or dill

Method
 

Roast and Mash the Garlic
  1. Roast a whole head of garlic: slice off the top, drizzle with olive oil, wrap in foil, and bake at 200°C (400°F) for 35–40 minutes until soft and caramelized. Let it cool completely. Squeeze the cloves into a bowl and mash with a fork into a smooth, uniform paste with no visible chunks.
Combine the Creamy Elements
  1. Add Greek yogurt and mayonnaise to the mashed garlic. Whisk or stir thoroughly with steady strokes until the mixture is fully smooth and evenly tinted light golden from the garlic. Proper mixing ensures no concentrated pockets of flavor remain.
Add Lemon for Balance
  1. Whisk in fresh lemon juice to brighten the sauce and prevent heaviness. The acidity sharpens the roasted garlic’s sweetness and gives the sauce a lighter, more versatile profile.
Incorporate Olive Oil and Season
  1. Stir in extra-virgin olive oil until fully blended. Season with salt and freshly ground black pepper, tasting as you go to keep the balance clean and rounded.
Finish with Herbs and Chill
  1. Fold in finely chopped herbs such as chives, parsley, or dill if using. Refrigerate the sauce for at least 30 minutes before serving to allow the flavors to meld and develop.

Notes

Roasting garlic is transformative. The long exposure to oven heat caramelizes the sugars naturally present in garlic, converting the harsh sulfurous compounds responsible for raw garlic's pungency into sweet, nutty, complex flavor molecules. The resulting cloves taste almost nothing like raw garlic — they are sweet, mellow, slightly nutty, deeply savory, and completely devoid of sharpness.
The ratio of Greek yogurt to mayonnaise is weighted toward yogurt for a specific reason: yogurt provides tangy brightness and a lighter body that balances the richness of the roasted garlic and prevents the sauce from tasting heavy. Increasing mayonnaise produces a richer spread; increasing yogurt produces a lighter, more drizzleable sauce.
The 30-minute resting period is non-optional when time permits. During this time, the lemon juice penetrates the garlic paste further, the herbs infuse the base, and the entire sauce knits together into a cohesive, more complex flavor.
