When cooking edible food...
1. Do you taste your food while you are cooking? If not how do you know what it taste like?
2. Are you cooking 2 fast meaning the temperature of your food is 2 high...this will cause your food to be dry and/or bland, and hard
3. You learn from your mistakes. I messed up and burned a lot of meals before I figured out what not to do when I was left alone in the kitchen, this just comes from practice and not being afraid to try.
You simply need to get in the kitchen more and experiment, my mom was a dietician at a hospital and she would always bring new recipes that they got for me to cook at him. So if the family liked it then she cooked it for work.
Take your time, read the directions and follow the directions, and lower the temperature on the stove.
For seasoning I use a combination of sea salt, onion powder, garlic powder, basle, parsley, black pepper, onion, green onion and celery....when baking always cover with foil and maintain a liquid in the pan.
Use a variety of seasoning for the perfect taste. and you have to taste your food as you are cooking to see if anything extra is needed. Also when the food is really hot the seasoning is not as strong as it will be once the food cools down.
If you burn or stick your food cut a potatoes in half and a onion in half put in a put pour the remaining unstuck or burned food in the new pot (please do not stir stuck food) and continue cooking the potatoes and onion will draw the burnt taste out.
If you use too much salt add a little sugar, if you use too much sugar add a little salt.
I think the biggest problem for people who say they can't cook is PATIENTS...
Good Luck
