Instructions
Remove any loose, papery layers from the garlic bulb/head. Slice off about ¼ to ½ inch from the stem/pointy side. Cut just enough to expose the tops of all the cloves. Leave the root side of the bulb intact so cloves stay together.
Drizzle the exposed cloves with cooking oil and wrap the bulb completely in foil. If you’re roasting multiple bulbs, wrap each one separately.
Air fry in a preheated air fryer at 380°F (190°C) for 20 to 24 minutes, until the cloves are soft. Alternatively, you can roast in a preheated oven at 400°F (200°C) for 30 to 35 minutes. Roasting time can vary depending on the size of the bulb.
Let the garlic cool for a few minutes, then squeeze the roasted cloves out of their skins into a bowl. Add truffle oil, lemon juice, black pepper, cayenne, and salt, and mash it all together with a fork.
Add this mashed mixture to the mayonnaise and mix well. Taste for truffle flavor. If it’s too weak, add a little more oil, a few drops at a time. The flavor can get strong really fast, so be careful. If you try this recipe, I’d love to know how it turned out through ratings and comments.
Notes
Note A: Truffle oil – These oils can vary a lot in flavor intensity depending on the brand and type. That’s why I’ve mentioned a small quantity to begin with. You can use either black or white truffle oil for this aioli, but black tends to be stronger and more pronounced.
