There are many types of food that are horrible in their supermarket versions, such as Pop Tarts, Spam, corned beef hash, "pressed" sandwich meats etc. I wonder if there exist tasty versions of these foods or appetizing ways to prepare them.
For example, one can make delicious fruit tarts, but can anyone make a nice pastry from the dry tasting filling in Pop Tarts?
Was there once a version of corned beef hash that people actually liked?
I've seen many recipes for preparing Spam, but none that would make me prefer it to hamburger.
Luncheon meats that are simply "sliced" make a good sandwich, but the ones that are "chopped, pressed and sliced" are disgusting. Nowadays you find this done to chicken and turkey as well as the traditional baloney.
