In a large mixing bowl (or the bowl of a stand mixer attached with a whisk attachment), whisk together cake mix, flour, sugar and salt. In a medium bowl, combine eggs, sour cream, water, cherry syrup and almond extract. Add egg mixture to flour mixture all at once. Beat on low speed for 30 seconds, then on medium for 2 minutes, scraping sides of bowl as needed. Fold in 3/4 cup chopped maraschino cherries.
