  • Patent number: 6055901
    Abstract: A cooking set including an perforated inset and a support ring. The support ring is adapted to fit within and rest upon the rim of a conventional cooking pot or dutch oven to support the inset at various heights. The inset is adapted to fit within the support ring so that it can be lowered into and raised out of the pot. The support ring defines a set of notches and the inset includes a set of corresponding protrusions. When the notches and protrusions are aligned, the inset can be lowered into and raised out of the pot. When the protrusions are not aligned with the notches, they can engage and rest upon the support ring to support the inset in a raised position. In the most preferred embodiment, the inset includes multiple sets of protrusions, each set positioned at a different height along the wall of the inset. Each set of protrusions permits the inset to be supported at a different height.
