To do well, you must be able to taste delicious food first. Of course, you are not required to have the taste of a gourmet, but at least you can't deviate from the public taste. In that case, you should try the food that everyone thinks is delicious first. In this respect, you can buy some food magazines and introduce where the food is famous. You can try it. Write down the taste of food with your sense of taste.

Then, you should buy "kitchen tools", that is, spoons, mixers and so on, which are good helpers to help you adjust the taste of dishes when cooking. So, for beginners, don't save!

Furthermore, you need to buy an adaptive cookbook, cook the dishes according to the method in the book, give them to your friends to taste and let them express their opinions.

This is my personal experience, I hope I can help you.
