Remove avocados from serving board. Cut each avocado in half, remove the seed and peel. Slice or cut each avocado as follows:
For avocado wedges: slice avocado half lengthwise into wedges about ½-inch wide at its widest part. Gently pile into an empty space on the serving board.
For avocado cubes: Cut avocado half into ¾- to 1-inch cubes. Gently pile into an empty space on the serving board.
For avocado fan: Place avocado half flat side down on cutting board. Slice avocado half length-wise into very thin slices. Gently press down on the rounded end of the slices to create a fan. Use the broad side of your knife's edge or a thin spatula to move the avocado fans to a spot on the serving board. You may use more than one avocado to create multiple overlapping fans.
For avocado rose: Place avocado half flat side down on cutting board. Slice avocado half cross-wise into very thin slices. with both your hands, carefully slide the slices apart into a "caterpillar," then shape into a rose by curling the caterpillar, starting with the smaller end. Gently press down on the slices and outward from the center to "open" the flower shape. Use the broad side of your knife's edge or a thin spatula to move the avocado rose to a spot on the serving board. Generally, one avocado half creates one rose.
For whipped avocado: Place two halves of peeled avocado in food processor. Add ¾ teaspoon salt, 1 tablespoon lemon juice, 1 tablespoon ice cold water, and 1 tablespoon mild olive oil. Run food processor until avocado is pureed and has the consistency of frosting. Add more water, then olive oil, 1 teaspoon at a time until you get the desired consistency. You can also use a blender for whipped avocado. Transfer Whipped Avocado to a small serving bowl, then place on the serving board.
Garnish the board with edible flowers and fresh herbs.
Add small serving spoons and forks. Cheese serving tools work well for sliced and cut avocado!
Leftovers: Avocado halves can be stored in an airtight container in the refrigerator for up to one day. Rub the cut surfaces with olive oil first. Generally, leftover sliced or cut avocado does not keep well, no matter what you do to it to keep it from browning. Your best bet is to freeze untouched wedges, cubes, and slices and use for smoothies. Whipped Avocado, depending on the avocado itself, may keep up to one day in an air-tight container in the refrigerator. Treat Whipped Avocado as you would guacamole.
Other fruits, vegetables, and other ingredients can be stored in zipper plastic bags or airtight containers in the refrigerator.
