A form-retaining pad for preparing a beverage suitable for consumption includes a first covering and a form-providing stiffening body, and a substance which is soluble in a liquid. The covering includes a top sheet and a bottom sheet that are manufactured from a material non-transmissive to the soluble substance, but transmissive to the substance dissolved in a liquid. The form-providing stiffening body is between the top sheet and the bottom sheet. The stiffening body has a compartmenting wall configuration having a grid structure which is transmissive to liquid from the top side to the bottom side. At least a part of the soluble substance is accommodated in the grid structure, and each compartment is surrounded by the wall configuration, the top sheet and the bottom sheet. At least the bottom side of the stiffening body includes a bulging part extending away from the top sheet.
