Fire can be done with 3 samples

1 - Blow in to the mic.
If yo blow in your microphone and record it you'll see that you'll have an awesome sample for fire wind, the lows.

2 - Crumple a piece of paper
This one is great for crackles and ignite sounds, mix it with the other sounds and it'll sound awesome

3 - Bubble Wrap
And this is the most fundamental sound, the crackles, if you mix this three sounds correctly, you'll get an awesome fire sfx
