2 tsp (10 mL) unflavoured gelatin
1 cup (250 mL) milk
3/4 tsp (4 mL) cinnamon
2 egg yolks
3 tbsp (45 mL) granulated sugar
1/2 tsp (2 mL) vanilla
2/3 cup (150 mL) whipping cream
1/4 tsp (1 mL) cinnamon
In small bowl, sprinkle gelatin over 2 tbsp (25 mL) water; let stand for 5 minutes to soften.
Meanwhile, in small heavy saucepan, heat milk and cinnamon over medium heat until bubbles form around edge.
In bowl, whisk egg yolks with sugar; whisk in hot milk. Return to saucepan and cook, stirring, over medium-low heat until mixture is thick enough to coat back of spoon, about 10 minutes. Remove from heat. Add softened gelatin; stir until dissolved. Add vanilla. Pour into large bowl. Place plastic wrap directly on surface; refrigerate, stirring twice, until consistency of egg whites, about 1 hour.
In bowl, whip cream; fold one-quarter into gelatin mixture. Fold in remaining whipped cream. Pour into 4 greased 6-oz (175 mL) fluted moulds, ramekins or custard cups. Cover and refrigerate until firm, about 6 hours. (Make-ahead; Refrigerate for up to 2 days.)
Garnish: One at a time, run knife around edge of mould, or warm mould for a few seconds in bowl of hot water. Invert chilled serving plate onto mould; invert to unmould mousse onto plate. Using fine mesh sieve, dust cinnamon over mousse and plates.
