Preheat oven to 350°F.
In a medium bowl, combine graham cracker crumbs, melted butter, sugar, and a pinch of salt. Stir until the mixture is evenly coated and crumbly.
Press the mixture into the bottom of individual muffin tins. Use your fingers to evenly press the crumbs up the sides to form a crust.
Place the muffin pan on a baking sheet and bake for 8–10 minutes or until lightly golden and firm. Let the crusts cool completely.
In a bowl, combine the Bellwether Farms A2 Organic Whole Milk Yogurt, lemon juice, honey, egg white, and a pinch of salt. Whisk until smooth.
Spoon the lemon yogurt mixture into each cooled tart crust, smoothing it out to fill evenly.
Bake the filled tarts at 350°F for 10–12 minutes until the filling is set and slightly golden around the edges.
Allow the tarts to cool to room temperature, then refrigerate for at least 1 hour to fully set.
Enjoy!
