Gourmet Black Truffle Mushroom Burger Aioli

1.In a large, non-reactive mixing bowl, combine the mayonnaise, black truffle mushroom sauce, and Dijon mustard. Whisk thoroughly until the mixture is completely homogenous and smooth.

2.Slowly drizzle in the black truffle oil while continuously whisking. Start with 80ml and taste. Truffle oil is potent, so add the remaining oil incrementally until the desired intensity is reached.

3.Add the fresh lemon juice and garlic powder. Whisk again to incorporate the flavors evenly. The lemon juice provides necessary acidity to cut through the richness.

4.Season the sauce with fine sea salt and freshly ground black pepper. Start with small pinches and adjust seasoning until the flavor profile is sharp and balanced.

5.Fold in the finely minced fresh chives. The chives add a visual element and a slight oniony freshness.

6.Transfer the sauce to an airtight container. For optimal flavor development, cover and refrigerate for at least 4 hours, or preferably overnight, to allow the flavors to fully meld. The sauce will also thicken slightly upon chilling.

7.Before serving, give the sauce a final stir. Store refrigerated and use within 5-7 days for best quality.
