2/3 cup white sugar
1 1/2 cups milk
2 (.25 ounce) packages unflavored gelatin (such as Knox ®)
2 cups boiling water
2 teaspoons almond extract
1 (11 ounce) can mandarin orange segments, undrained
Whisk the sugar into the milk in a mixing bowl until dissolved.
Sprinkle the gelatin over top, and let stand for 1 minute to soften.
Whisk the boiling water and almond extract into the gelatin mixture until the gelatin has dissolved. Pour into a 7-inch square pan.
Refrigerate until firm, about 4 hours.
Once firm, cut the gelatin into 1-inch squares, and place into a mixing bowl. Gently stir in the mandarin oranges and their juice to serve.
