Sometimes there are folk who grow up with bad food all of their lives and all they're comfortable with is, well, bad tasting or poorly prepared food. It's like someone who endured their mother or father's terrible cooking and so they cook the same, or worse, then, they feed it to their children...thinking that this is how it's supposed to be and the children learn to be unable to discern the difference between good tasting food and really bad food.
For myself, I keep trying to get it right with my cooking and food preparation for sometimes it's great and other times, well...
I can readily admit when I've struck out trying to prepare a really tasty and wholesome meal.
My wife and I will periodically watch food shows on television, some from around the world. We learn secrets from foreign lands, near and far and how they use different seasonings and the variety of ways to prepare delicacies indigenous to their particular culture and upbringing.
I've discovered that the best cooks who seem to really know what they're doing aren't pretentious nor glamorous or pretty. They simply have the taste buds for what is right and good and know how to use quality products with the right ingredients and the perfect amount of seasonings that suits them and the folk that they are preparing the food for.
People who lack a discernible palate will decimate good quality ingredients with the wrong seasoning, improper handling, under-cooking or over-cooking...and, what's worse, they don't even know what they've done wrong or even that they've done anything wrong to make the food taste bad. Bad food just tastes the same to them. The indiscernible palate will make the good bad in order to have what they're used to and most comfortable with; that is, bad food. Furthermore, their children will grow up with the same indiscernible palate, oftentimes repeating the same process by teaching others to do the same...make bad food and eat it, thinking that it's good, or thinking that this is how it's supposed to be, so why complain.
Even still, there are others who think they know good food when they taste it because they have partaken of fine delicacies and great quality food. These folk strive to work and busy their lives in order to purchase richly prepared dinners. Somehow, they believe that because of their income level, they deserve to eat the best; they certainly do not know how it's prepared, and they really don't care, because their finances afford them the luxury of lavish meals at any cost. It is their finances that give them the illusion that they have a finely established palate discernible to the richest of tastes, when in truth, the discernible palate for that which is good doesn't really cost anything but the ability to know that good is good and bad is bad and there is no fine line in-between the two.
One either knows good food and recognizes it or they don't. It is what is inside the person that discerns the good from the bad and that doesn't cost a dime.
