I don't know if this will help with Ella but Racci is the same way and one of the worst I've seen. I get her texture just the way she likes it with water and put it in the microwave to the exact temp she likes. I bring her on the ottoman with me & put it right in front of her making a super fuss about how wonderful her food is so she has to smell it to see what I'm raving about out of curiosity. if she still refuses to eat, I prod her a little and continue to tell her i made it just the way she likes it, and taste it, etc. If she still won't try it, I pick it up and walk into the kitchen and 'fix' it, usually by putting my finger in and stirring it or putting a tiny bit more solid or water to the mix or heating more and stirring again. She will usually eat it the second time when I tell her I fixed it and help her eat it with my fingers.
