ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to cooking utensils.
2. Description of Prior Art
The food contacting surfaces of cooking utensils are commonly formed of or coated with non-stick materials so that such surfaces are more easily kept clean. Nevertheless non-stick coatings are subject to damage and wear, even when washed and rubbed with normal cleaning cloths and pads available in the kitchen. More often than not, the contacting surfaces include crevices and ledges where it is difficult to remove burnt-on foodstuffs and it is often impossible to soak the utensil suitably in water to loosen stuck-on foodstuffs. Such problems arise in a griddle or sandwich toaster which are preferably formed with a complex, e.g. patterned, contacting surface.
SUMMARY OF THE INVENTION
It is an object of the invention to reduce or overcome this problem.
According to the invention there is provided a cooking utensil having heatable complex contact surface for preparing foodstuff including a removable self-supporting complimentary shaped liner formed of heat conducting material formed to mate with and fit snugly against at least a major part of the contacting surface, including releasable holding means to maintain said liner in intimate contact with said contacting surface, said liner retaining said complimentary shape upon removal from said utensil.
The liner is preferably formed with a non-stick coating that contacts the foodstuff in use.
The liner may extend to some extent beyond the heatable contact surfaces.
The liner is preferably formed of alumina.
The cooking utensil may have heatable contact surfaces formed by a metallic plate and the liner have a thickness that is less than 50% of the thickness of the plate.
The cooking utensil may comprise one of a sandwich maker, a griddle and a multi-pie maker.
