I have long desired a cast iron enameled insert to a slow-to-fast cooker. I could sauté the onions and brown the meat and then place the whole pot in a slow cooker using the usual temperatures but in this invention, I'd have a dial and choose my temperature up to the electric skillet range.
This eliminates washing the skillet that the meat was browned in, or having the blandness of skipping the frying and just dumping in the meat. The pot could be used on the stove top and would have a flat bottom so it could be used on an electric stove as well as gas.
This pot would come with a domed lighter weight metal cover that would fit over quart jars so that you could ferment yogurt at 100° or your choice of temperature. Most electric cooking devices begin at 150° probably because that is considered a safe holding temperature for food.
Why this is diffierent:
Insert can be used as any Le Creuset type pot on stove top and in the oven and can fit in it's own slow cooker base. I could also sauté right in the base.
It can ferment yogurt at 100° which is lower than anything except a specific yogurt maker.
With a stainless second bottom, I could deep fry with a basket.
It eliminates a separate skillet to brown the meat.
It would have a cord caddy arrangement to keep it tidy.
