A solid and liquid separating device includes an inner container and an outer container. The outer container is sized to receive the inner container. The inner container retains solids. The inner container includes an open bottom that is covered by liquid permeable membrane. The liquid permeable membrane is preferably stretchable. The outer container is filled with a liquid. The inner container floats on a top of the liquid in the outer container. A utensil (such as a spoon) is inserted into the solids and pressed into a portion of the liquid permeable membrane. The liquid permeable membrane stretches and allows liquid to enter the inner container. The liquid combines with the solids in the inner container. When the utensil is withdrawn from the liquid permeable membrane, the liquid no longer enters the inner container. The inner container now floats on the liquid in the outer container.
