Gas flame simulation help please!

Very grateful for any advice here please folks.

I need to reproduce this flame:

It’s a rapidly flickering gas burner flame, deflecting off the roof of an oven. The burner itself is only about six inches in diameter, the fire covers an area about twice that.

I have spent days attempting it by trial and error, in both the old smoke sim and Mantaflow, and I am tearing out my overgrown lockdown hair. The main problem is that the more I increase the quality settings, the larger-scale the result appears. So I either have a fuzzy, blurry blob of orange light, or napalm.

How would you go about recreating this effect?

I wish I had the knowledge to tell you how you should do it, but I don’t. I did happen across a YouTube video teasing an upcoming tutorial that looks a lot like what you are trying to do. Maybe keep an eye on that channel to see when the full tutorial drops.

That does look promising, thanks for the tip, I will indeed keep an eye on it!
