Grandma's Meringue Cookies

Steps

1. Preheat oven to 225°F. Line a baking sheet with parchment paper.

2. Mix egg whites and lemon juice until foamy. Add tartar and set mixer to medium high.

3. Beat in sugar 2 tablespoons at a time, mixing after each addition. Continue mixing until shiny and stiff peaks form, about 3-4 minutes. Ensure the sugar is dissolved.

4. Fit a large star tip onto a piping bag and fill with the meringue mixture. Pipe into 1-inch kisses. Add sprinkles if desired.

5. Bake for 1 hour or until firm. Turn the oven off and leave meringues in the oven at least 3 hours or overnight.
