Of course it's sarcastic George. The recipe is defined, and to prepare the dish as intended it should be followed. My comment is light hearted dig at the multiple instances in the video where variation or omission of what would appear to be integral ingredients is mentioned. Tej patta, cassia bark, lemon juice and jaggery to name the obvious ones.
Is the dish the same if you use European Bay leaf, cinnamon, lime juice, brown or refined sugar? Prawn, raw chicken, pre-cooked chicken, lamb or vegetables? All very different variations of the pathias cooked on Sunday. Factorial 10 is 3628800 possible variations just from these listed ingredients. Then if you take into account powdered spices and base gravy the possibility of any 2 dishes cooked on Sunday being identical is remote. (Of course you aren't going to use combinations of lamb, chicken and prawns but you could use 1 and vegetables so Factorial 5 or 6 is still quite a large number of possible variations).
Does it matter? Not in the slightest.
I also had a chuckle at the hosts assumption that people using vegetables know how long to cook the different ones "because they are vegetarians". It's a light-hearted video, a wonderful idea and very entertaining. It inspired me to buy 600 grams of lovely green prawns for tonight's dinner, which I will attempt to prepare to specification.
