In a small bowl or cup, dissolve the Junket tablet in the cold water.
In a small saucepan, heat the milk to lukewarm (98°F). Remove from the heat.
Stir in the granulated sugar, vanilla extract, and food coloring. Then, when the sugar is dissolved, pour the Junket tablet and water into the milk and stir briefly.
Pour the mixture into four serving bowls and let sit at room temperature for about 15 minutes. Then, refrigerate until serving time. Ideally, at least 2 hours.
When ready to serve, whip the whipping cream with the powder/confectioner sugar until stiff peaks form.
Spoon the whipped cream on top of the junket and top with the sliced strawberries. Dust more powder sugar on top if desired.
Notes
You can use a whole Junket Tablet for a firmer set.
