In a spacious mixing bowl, gently beat together the softened butter, confectioners' sugar, and salt on low speed until they are just combined. Then, increase the speed to medium and continue beating for about 2 minutes until the mixture looks light and fluffy.
Reduce the mixer speed to low. Add the maraschino cherry juice, almond extract, and the optional red food coloring (if you're using it). Mix well. Next, carefully fold in the chopped maraschino cherries.
Gradually add the all-purpose flour to the bowl on low speed, mixing just until everything is combined and a soft dough forms. Be careful not to overmix!
Take small portions of the dough, about 1 1/2 tablespoons each, and roll them into smooth, 1-inch balls. Place these dough balls on ungreased cookie sheets, making sure to leave about 2 inches of space between each one.
Preheat your oven to 350°F (175°C). Bake the cookies for 8 to 10 minutes, or until the edges are just beginning to turn a very light golden brown.
As soon as you remove the cookie sheets from the oven, immediately place one unwrapped Hershey's Kiss into the center of each warm cookie. Press down ever so slightly. Don't worry if the cookie cracks a little around the edges—that's perfectly normal!
Let the cookies cool on the baking sheet for a couple of minutes before transferring them to a wire rack to cool completely. Once fully cooled, these delightful cherry-chocolate treats are ready to be savored!
