"I cook with wine, sometimes I even add it to the food"

This quote by W. C. Fields is a humorous method of revealing his love for cooking with red wine. He is recommending that he not only utilizes white wine as a component in his cooking, but also includes it to the food itself. This could be analyzed as a metaphor for how he includes a distinct flavor to his cooking, or it might be taken actually as a tip that he adds wine to the food he is preparing. Either way, it is clear that W. C. Fields wants cooking with red wine and delights in the flavor it adds to his dishes. He is also most likely suggesting that wine can be used to boost the flavor of food, and that it can be a fantastic addition to any meal.
