Which of the following is a common filling for Danish pastries?

Fruit preserves are a common filling for Danish pastries due to their sweet and flavorful nature, which complements the flaky and buttery texture of the pastry itself. Danish pastries are traditionally sweet baked goods that often incorporate fruit fillings to enhance their taste and visual appeal. Common fruit preserves used can include apricot, cherry, raspberry, and blueberry, allowing bakers to create a variety of options that cater to different palates.

The use of fruit preserves not only adds sweetness but also introduces moisture and a burst of fruity flavor, making them a popular choice among consumers. In contrast, the other options are less fitting for traditional Danish pastries due to their savory or unconventional nature in this context, as Danish pastries primarily focus on sweet flavor profiles.
