1Preheat your oven to 180°C (350°F).
In a mixing bowl, combine the almond paste and sugar until smooth.
Add the eggs one at a time, mixing well after each addition.
Melt the butter and let it cool slightly, then add it to the almond mixture.
In a separate bowl, sift together the flour and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Pour the mixture into a tart pan, spreading it evenly.
Bake in the preheated oven for 25-30 minutes, or until the tart is golden brown and a toothpick inserted into the center comes out clean.
Allow the tart to cool before serving.
