Answer:
According to the recipe, B) When the color of the paste begins to lighten slightly, it has been beaten enough.
Step-by-step explanation:
Creaming or Beating is amongst the most essential techniques of blending used in the recipe. The paste's appearance seems to have become lighter when it is thoroughly beaten as the air bubbles have now been added to the paste; When the appearance of the paste becomes lighter, we came to know that that the paste has been beaten enough. Hence, option (A) is correct.
Since the recipe is not mentioned, considering the question asked according to the mixing method, the paste will stick to the wooden spoon even if the paste is not beaten. No one will use an oven to test the beaten consistency of the paste. As we never know why the paste is being used for, we should not consider that it is correct to have the consistency of the pudding. So, options (A), (C) and (D) are incorrect.
