In a saucepan, Pour in a can of coke (I Kid you not).
Add half a cup of tomato sauce(I Kid you not)
This is the BASE
You simmer the liquid down until it has the thickness you want.
Now for surf and turf:
To the base you could add: Sake, Rice vinegar, Oyster sauce, Fish sauce, Hickory smoke water (I you like BBQ) , Chinese five spice,
Thers more , And not all at once.
Only a little of the after base flavours or it will be over the top.
Or in the case of sake, Mix half base and half sake to make a jus.
