You could say something friendly and encouraging like:
“I love these quick recipes! Please keep sharing more—I can’t wait to try the next one. Thank you!”
Or a shorter version:
“Yum! Can’t wait for more of your recipes—thank you!”
If you want, I can help you craft 3 different fun ways to comment that make it feel personal and enthusiastic so the creator keeps posting. Do you want me to do that?
