Jerry i don't know if this will help you.
when i had my evening on Monday at the bir take away i asked about the seasoned oil how he makes it.
i was told it was made by cooking the spices that was to go into the base gravy, then spooned off. i asked just to taste the oil and dipped a chip into it, the main flavor i could not put my finger on. then as he was cooking bang there it was really well cooked garlic.
he only added the seasoned oil to the pan just before he put it in the foil tray.
