The best way to cook tenderloin:
>Toast some spices (Star Anise, Mustard etc.)
>Make it spicy
>Oil up the pan with some Extra-Virgin Greek Olive Oil
>Onions
>Salt the steak
>Place it in the pan
>Wait until almost cooked
>Flambe with some Cognac
>While the Alcohol is still on fire throw in some cinnamon (Cool Harry Potter explosion effect)
>When the alcohol has evaporated throw in some fresh herbs (Oregano, Cilantro etc.)
>Take it out of the pan
>Lime
The tenderloin should be spicy, salty and aggressive which is why you should balance it out with a cool and fresh sauce:
>Extra Greek youghurt
>Some coconut cream (optional)
>Add Lemon Verbena and Spearmint
>Lime
>Mix it up
Serve meat and sauce seperately.
It doesn't have to be tenderloin but other kinds of meat don't need as much spice and flavor.
