Let's imagine it's alreay 3006 and an efficient time machine allowing speed up or slow down the time within a certain volume of space was constructed several decades ago and since then this technology developed as intensively as computers from 1950 to 2006, so now a time machine has a size of a laptop and needs as much power as a toaster to work.
There I see a wonderful application of its functions in cooking! In order to season the green walnut jam or wine or bake a turkey or unfreeze meat or cool down kissel, meat-jelly or ice-cream, you only have to choose the necessary mode of time convertion or keep any delicate products from spoilage you only have to place the products into this portable kitchen time-machine, designed just like a microwave oven, then set it to proper mode. Then you can have any stew ready in several minutes or store them for ages. The modes you may use are the following:
+++ 1 week passing per one minute (for seasoning wine of green walnuts)
++ 1 day
