In any chain grocery store, where you would buy the cupcake tins and whisks, there exists a stainless steel coil (~4in) attached to a plug in cord. This coil is made to keep liquid foods hot when clasped onto the side of any pot/heat-resistant bowl/or cookware. G**d C**k. I love its compactness, its freedom from hot plates in general. However, it gets a 2-quart pyrex bowl oil bath way too hot for my purposes. 275f. A knowledgeable friend suggested I make a rheostat but it is beyond my capabilities i believe. Is there something i can put in the bowl to lower the temperature of the oil? I know that I could use a much larger vessel and try lowering the temp that way but I want to ask this first because I like using scaled down things. If I am missing something obvious, please point it out after a suitable dressing down. Thanks.
