Trim the top of the garlic bulb so that the cloves are cut. Place the bulb on tin foil and drizzle with olive oil, season lightly with salt. Close the foil tightly and bake the packet in a 175-220 degree oven until the garlic is soft (about half an hour, can be made well in advance with other oven dishes). Squeeze the garlic out of the skins.
For the aioli, combine garlic, orange juice, zest, bread crumbs, egg yolks, mustard, vinegar, pepper, salt and a tiny bit of juice from one lemon in a hand mixer form and mix well. Then, while continuing to mix, slowly add the mixture of sunflower oil or other vegetable oil and olive oil.
Season the aioli.
Goes well with grilled mayor Mediterranean and oven-baked vegetables.
