Preheat the oven to 225, and line 2 large baking sheets with parchment paper.
Separate the eggs, making sure not to get any egg yolk in the egg whites (the meringues will not form if egg yolk gets in).
Add the cream of tartar and salt into the egg whites mixture. With an electric mixture start mixing on high.
Once the mixture becomes white and bubbly, start gradually adding the sugar.
Mix until the mixture forms stiff peaks (if you flip your bowl upside down, the mixture should stay intact and have a shiny, white appearance).
Stir in the pink food coloring and vanilla extract.
Transfer the mixture into a large piping bag with a small tip, and pipe small hearts onto the parchment paper. You can put them close together, as they do not spread.
Bake the meringues for 1 hour, and allow to completely cool before consuming.
