Do cakes with strawberry preserves as the filling need to be refrigerated?

Whether or not a cake with strawberry preserves as filling needs to be refrigerated depends on a few factors:

Factors that make refrigeration more likely:

* Type of preserves: If the preserves are homemade or contain fresh fruit, they are more likely to spoil quickly and require refrigeration. Commercial preserves often contain preservatives that extend their shelf life.

* Cake recipe: Some cake recipes, particularly those using perishable ingredients like eggs or milk, may make the cake itself more susceptible to spoilage.

* Temperature: Warm temperatures will accelerate spoilage.

General guidelines:

* Commercial Preserves: Cakes with commercial strawberry preserves can typically be left at room temperature for 1-2 days. However, it's always best to check the specific recommendations on the preserves jar.

* Homemade Preserves: Cakes with homemade preserves should be refrigerated.

* Cake Recipe: If the cake recipe includes ingredients that are prone to spoiling, it's generally best to refrigerate the cake.

In most cases, it's safer to refrigerate a cake with strawberry preserves, especially if you're unsure about the ingredients or the temperature. This will help to keep the cake fresh and prevent spoilage.

Here are some additional tips:

* Store the cake in an airtight container. This will help to prevent the cake from drying out and absorbing odors.

* Check the cake for signs of spoilage. If you notice any mold, discoloration, or an unpleasant odor, discard the cake.

Ultimately, the best way to determine whether your cake needs to be refrigerated is to consult the recipe and the label on the preserves jar. However, it's always better to err on the side of caution and refrigerate the cake if you are unsure.
