To: Editors of Eat Right Magazine As a long-time subscriber to Eat Right Magazine, I have frequently sampled your recipes and must credit you with some excellent results. Your recent April-May issue was, as always, packed with healthy, delicious meals, many of which I have already prepared at home. Several days ago, however, I attempted to make the apple and celery salad from the recipe on page 57 of the magazine in the Healthy, Quick, and Easy section. While the salad was flavorful, I was not satisfied with the recipe for two reasons. First, it should be noted that a salad containing 100ml of mayonnaise, to be divided among eight servings, is not particularly healthy. I was surprised to find a recipe with so much mayonnaise in an Eat Right recipe. Second, while the directions suggested that five minutes' preparation time was sufficient, I found the time to be underestimated by quite a bit. Finely slicing so much celery and so many apples was quite time consuming and certainly took longer than five minutes. You might adjust this assessment when you publish this recipe in the future. I look forward to receiving the next issue of Eat Right Magazine, and I hope that it will contain more of the simple, nutritious recipes that I have come to expect. Sincerely. Francesca Bertolini According to the recipe, what should be done first?
A. The apple should be peeled. B. The mayonnaise, cilantro, and lemon juice should be mixed. C. The celery should be chopped. D. The salt and pepper should be measured.
