Cut avocados in half, remove pit and skin; cube, and spoon avocado into a mixing bowl.
Mash avocados to desired consistency using the back of a large spoon or fork; squeeze the juice from half of the lime into the avocado and stir to combine.
Fold in remaining ingredients and the juice from the remaining lime half.
Store, covered, in the refrigerator. Remove an hour before serving.
Note: The lime allows the guacamole to retain its "avocado" color as it sits in the fridge. You can use lemon juice, but it affects the flavor more dramatically than lime. If you find the stored guacamole has darkened, stir it before serving.
