The brustolina is a grill which fits over a gas burner on a hob.[1] It consists of a square sheet of metal with holes punched in it[2] (the base) and a square grid over the top (the grilling surface). Heat is applied from below and is evenly distributed by the base, deflected upward to the grid. Items placed on top of the grid are cooked by both convection and radiant heat. These grills are often used in Italy, for instance, grilling bruschetta, polenta, vegetables or toasted pumpkin seeds.
A brustolina can also be used as a heat diffuser, to provide well-distributed low heat, for example for cooking rice.
They are economical and widely available in Italy and Chile.
Similar grills are used for making toast over campfires[3] and in Japanese cooking.[4] [5]
