When Should You Just Buy Prepared Kosher Food?
When nobody needs cooking on site. If the family is comfortable warming food according to its own practice and the menu does not need to be personal, prepared food from a kosher market or restaurant costs less and takes less coordination. This is a common case where hiring a chef is more service than the occasion requires.
Aventura, Surfside, Miami Beach and Hollywood all have kosher food retail within a short drive of most rentals and homes.
