Another Chocolate Filling

This filling cannot be made ahead as the uncooked meringue will break down and become watery. The egg whites can be separated up to 2 days in advance and stored covered in the refrigerator, but bring to room temperature and whip just before assembling the cake.

Once assembled, the cake should be refrigerated and consumed within 24 hours. The filling will gradually weep and lose volume. Store covered loosely with plastic wrap to prevent drying while allowing some air circulation. Note that this recipe contains raw egg whites and should be handled with food safety in mind.
