I ran into the same struggle after constantly pausing videos with flour on my fingers. What finally worked was using an app that mirrors the iPhone screen straight to the TV over Wi-Fi, without touching the TV menus at all. This iPhone to TV screen mirroring is what I’ve been using lately. I just open the recipe on my phone, hit mirror, and it pops up on the kitchen TV right away. No lag, even when rewinding or jumping between steps, and it saves me from trying to operate the phone mid-cooking.
