Flavoring
If you are making a fruit cake, then you may want to use fresh fruits as the flavoring agents. The other flavors which can be used are ground spices, extracts, citrus peels, citrus oil or even liquors. If you are going to use liquors, then it is recommended that you use only small quantities, as it has a tendency to dry out the cake. The other possibility is that it can cause the cake to fall. If there is too much liquid flavoring in proportion to the other ingredients used for baking, then the structure becomes weak.
