Pour the half-and-half into a small saucepan and sprinkle with the gelatin. Allow to soften for 3 minutes. Place over medium-low heat and bring the mixture just barely to a simmer, stirring often to dissolve the gelatin, about 5 minutes. Add the sugar and stir to dissolve.
Meanwhile, add the heavy cream, ricotta, almond extract, orange zest, vanilla extract, cinnamon and salt to a blender. Blend on low to combine. Add the warm half-and-half and blend to combine, about 10 seconds. Pour into 6 small ramekins. Sprinkle in the chocolate chips and refrigerate for at least 4 hours or overnight until set. Serve with the toasted almonds on top.
