Step 1

Line a baking sheet with some parchment paper and preheat your oven to 220 degrees F.

Step 2

Place the egg whites into a bowl and, using a hand mixer, beat until stiff peaks form. In a separate bowl, mix the cream of tartar with powdered sweetener. Add a spoonful of the mix at a time add it into the egg whites while continuing to beat at high speed.

Step 3

Add the lemon juice (and food coloring if you want) beat for a few more seconds.

Step 4

Place the mixture into a piping bag and pipe out some of it onto the baking sheet into cookie-sized shapes. Place the baking sheet into the oven and bake the meringues for 45 minutes.

Step 5

Turn the oven off and leave the oven door slightly cracked open. Leave the meringues in the oven for an extra hour. Then take them out and let them fully cool down at room temperature.
