Photoshop: I typed the word “hot” in a typeface called Krungthep. I used the smudge tool to make them look like that they are on fire, but I could not use the smudge tool on a type layer unless I first rasterized it. I used erase tool to make some holes in the word to make it look like the word is actually being consumed by the fire. Then used drop shadow to make the smoke.
