Vegetables and fruits for garnishes or side dishes should contribute visual interest to the plate by adding a contrasting shape. For a scallop dish, shape contrast can be created by cutting carrots into bâtonnets or juliennes rather than rounds. Melon cut into parisiennes contrasts nicely with pineapple cubes.
Vegetables or fruits that will be mixed together in a salad or medley should be roughly uniform in size. This looks best and makes eating easier. Soft vegetables, which are likely to shrink when cooked, should be cut slightly larger than firmer vegetables that will retain their original size after cooking.
