On a Rick Bayliss show, one of his cooks made a garnish he called
"black pepper air" - ground pepper in an emulsion, whipped with a
stabelizer. I must have missed something. A very fluffy cloud of, I
guess, pepper flavored air. Looks a little silly for my normal table,
but could be a useful trick for my stunt cook bag.

Have you heard of this?
