What goes in the bottom of a 1/6 pan containing prepped oranges?

The most appropriate choice for the bottom of a 1/6 pan containing prepped oranges is a drain shelf. The primary reason for using a drain shelf is to allow excess moisture and juices from the fruit to drain away, preventing the oranges from sitting in their own liquid, which can lead to sogginess and spoilage.

Furthermore, a drain shelf helps maintain the quality of the oranges by promoting airflow, thereby keeping them fresher for a longer period. It is designed specifically for this purpose – to elevate the fruit and allow drainage, while still being accessible for serving or using in recipes.

The other options, while they might have specific uses in a kitchen, do not provide the same functionality as a drain shelf. Ice may keep items cool but does not facilitate drainage. Wax paper and parchment paper are typically used for lining surfaces to prevent sticking or for food preparation, but they do not offer the same benefits of drainage necessary for keeping the oranges in optimal condition.
