1) Place cherries in a heavy medium-sized saucepan, and cook over medium heat, covered, for 10 minutes.
2) Meanwhile, combine cornstarch and sugar in a small bowl. Add lemon juice and whisk until smooth. Stir this into the hot cherries, and cook over medium heat, stirring frequently, until thick (5 to 8 minutes).
3) Remove from heat and stir in lemon rind, almond extract and slivered almonds. Serve hot, warm, room, temperature, or cold, top with whipped cream, whipped ricotta or yogurt.
To blanch almonds, place them in a colander over a sink. Pour boiling water over them, and rub off the skins. Cut vertically with a sharp knife to sliver them. To whip ricotta, beat it vigorously with a whisk or at high speed with an electric mixer.
