To achieve proper marination, which technique involves the periodic movement of raw products?

The technique that involves the periodic movement of raw products to achieve proper marination is rotation. This method ensures that all surfaces of the meat or vegetables come into contact with the marinade, promoting even flavor distribution and enhancing the overall taste and tenderness of the product. By regularly turning or rotating the items, the marinade can penetrate more deeply and uniformly, which is crucial for achieving optimal results.

In contrast, soaking refers to immersing products in the marinade without the added benefit of movement, which can lead to uneven flavor absorption. Simmering is a cooking technique that involves gently heating food in liquid, whereas turmeric is a spice and not a technique related to marination. Therefore, rotation is the most effective method for ensuring that all aspects of the raw product benefit from the marinade.
