Under what circumstance can powdered or evaporated milk products be used?

Powdered or evaporated milk products are primarily utilized as additives in cooked foods due to their concentrated form, which enhances the texture and flavor of various dishes without adding excessive liquid content. This versatility allows them to be integrated into sauces, soups, and baked goods, where they provide creaminess and depth of flavor.

While they can also be used in other capacities like cold beverages or as part of a dietary supplement, their most common usage in culinary contexts is as an ingredient that complements and enriches the overall dish. This aligns with standard practices in cooking and food preparation where powdered or evaporated milk serves primarily as an additive rather than a standalone dish.
