Set a nonstick griddle to high heat.
In a small bowl, mix the flour, baking soda, nutmeg, salt, and sugar. In a large bowl, whisk together the milk, ricotta, eggs, lemon juice, and zest.
Add the flour mixture to the wet ingredients and mix them just until they are mixed. Spread butter on a hot griddle.
Pour about 1/4 cup of batter onto the griddle for every pancake, and cook until lightly golden brown on both sides. Continue until there is no more batter.
Pour the lemon curd into a small saucepan and warm it up over low heat. Alternatively, take off the lid and heat in a microwave on half-power for 2 minutes, stopping for 1 minute to mix the curd.
Top each pancake with a few tablespoons of curd, then garnish with fresh raspberries and confectioners’ sugar.
