As much plaster mix as you can get in the water and still manage to get a pour with some resolution. The less plaster to water, the easier it is to pour and the weaker the mold. More plaster, stronger mold.

Mixes based on volume are not accurate since a given volume of dry powder may be firmly packed or lightly packed. If you don't have a scale just pour the dry mix into the water untill it peaks, let it slake for 5 minutes then mix.
