For plate and cocktail garnishes, a simple way to release those oils is with a good slap.
Just place the leaf or leaves in your palm and give it a nice firm smack.
The slap breaks down some of the cell structure in herb, which in turn releases the oils.
Now you get the flavor enhancement without a crushed, chopped, or muddled mess.
