I have been told you can pour it over their F/V if you have a hard time getting them to eat them. And that goes for all of the HPW's. I've never done it because mine don't like it all mixed together.
I honestly don't know if you can force her to eat it. I was feeding Original HPW for over 6mo. when mine decided to stop eating it, and they held their ground... I mean 2 -3 nights in a row they wouldn't touch it. I caved before they did and had to get them some food. Not sure if anyone has ever outlasted a not eating suggie... we all worry so much about their food intake I think most of us give in before they do.
I personally really like the Original HPW...even have a batch sitting in my freezer hoping that one day I'll be able to give it and they'll eat it,....no such luck as of yet....but as we always say, you can be feeding what you think is the best diet out there but if your babies won't eat it, it's not worth much.
