I would say if you're just starting and you're just keeping the tarts for yourself and close family, Id say use some ice cube trays. You can buy a whole bunch and just pour. Also, if you want pretty ones keep your eyes open at the dollar stores, because you can find ice cube trays with shapes. I have heart shaped ones from Target that I use. I hope I helped and good luck. Put your next batch in the gallery so we can all see them.Becky
