Answer: c. Move them straight from the freezer into a pan or a steamer
Explanation:
Frozen vegetables are those vegetables which are kept at a lower temperature in the refrigeration conditions below the freezing point for storage and transportation until they are eaten. The freezing process restores the quality of these vegetables.
The frozen vegetables must be washed in the cold water until these get thawed. Add these vegetables into the pan or a streamer. Cook as usual. As these frozen vegetables get blanched or boiled before they are frozen, thus there is no requirement for pre-cooking of these vegetables before they are added to the recipe.
