[[1]] is the method used to separate cream from curd.

We shall learn about the technique used to separate cream from curd in the answer to the question. We'll employ a technique that, within seconds of a combination being rotated at a very high speed, helps separate mixtures.

When separating mixtures in the same condition, such as cream and curd, the particles are separated from the solution based on the density, size, shape, medium viscosity, and rotor speed of the medium. The process is referred to as centrifugation. And the use of centrifugal force is a component of the substance separation method known as centrifugation. The machine is referred to as a centrifuge.

The cream, which is lighter than curd and can be readily retrieved from the curd and separated, will float on top of the curd when it is cycled into the centrifuge at a high speed, while the denser particles sink down at the bottom and the lighter ones float over the surface.
As a result, the centrifuge operates on the sedimentation principle, which separates materials based on their densities beneath the influence of gravity or g-force.

Hence, the answer is Centrifugation.
