Basil mayonnaise transforms an ordinary sandwich to a summertime staple; make extra and use it on everything from grilled corn to egg salad to lobster rolls.
Ingredients
1 cup packed basil leaves, finely chopped
3 tablespoons extra-virgin olive oil
pinch kosher salt
1 egg yolk
1 tablespoon lemon juice
1/2 cup canola oil
1 teaspoon white wine vinegar
4 slices multigrain bread
1 ripe avocado, sliced
2 cups sprouts
1 cup shredded red cabbage
2 handfuls green leaf lettuce
1 cup shredded carrots
1 large cucumber, sliced thinly
1 ripe tomato, sliced
Directions
For the mayonnaise: Whisk together the egg yolk, lemon juice, vinegar, and salt in medium bowl. Whisk rapidly until well-combined (about 45 seconds).
Very slowly drizzle in the olive oil, a little at a time, whisking as you go. Then gradually and slowly drizzle in the 1/2 cup of canola oil, whisking constantly (you can use a food processor for this if you prefer), until the mayonnaise thickens.
Whisk the finely chopped basil into the mayo (I often blend it with a blender or food processor quickly), then refrigerate for at least 1 hour to let the flavors mellow together.
For the sandwich: Spread the bread thickly with the basil mayonnaise, and layer on the remaining ingredients, dividing them evenly between both sandwiches. Adjust to your taste!
