ah.. you misunderstand the burger theory Miss glitterfairy.
The burger is not pre-made and reheated, only the ingredients are prepared before hand.
Its like when you open a resturant, you can't go open until you've got the tables, chairs, cutlery all ready and set. Thats just making you look organised and calm to attract customers (not panick before exam).
Then in the kitchen, you won't make everything that you can offer. You don't have the time and money to do that! You can only prepare the main ingredients that is needed in all your courses (paragraphs). Still need to season the meat IF they order it. You're a quality resturant, if you serve pre-made pizzas from Franklins, you're gonna go bankrupt (lose marks)!
First, customer orders, then, and only then, do I place the ingredients in the way they want it cooked.
Formulas, techniques whatever you want to call it, are to get newbies at english tackle it at a understandable level, get them in the correct mindset when they begin! (you can compare it to pickup lines when to the game
)
After countless times of practicing, they've understood and applied all the basics, they'll realise that there are no more need for 'techniques', then, and only then, they will have mastery.
amen.
