Crunchy.
I couldn't find any brand of fruit granola called カリカリ (crunchy) so it's a nickname they made up.
Edit: In other news, I just bought the raws from a retailer which are slightly higher quality than the ones on Pixiv. Plus, each chapter has a proper name now (I thought the Pixiv descriptions were suitable chapter names so I used those up until now). So, I'll be spending a bit of time improving the chapters I've already scanlated.
Edit 2: The raws are only a tiny bit better resolution, so I didn't bother upgrading them (lots of redrawing required). So all I ended up doing was adding the official chapter titles and changing a few minor things.
