First time I tried this and cakes rose about 1-1-1/2" above top of jar, Pushed cake into jar and added glaze. It was about 5-10 min. before I put the lids on. They did not pop but look and feel tight. Is is safe to mail these to Irag or need i start over with a new batch? Thank you. Pls ans quickly as I need to get this box sent.
