In a large bowl, whisk together the ricotta, buttermilk, eggs, sugar, lemon zest, lemon juice, and vanilla. In a medium bowl, whisk together the flour, cornstarch, baking powder, and salt. While stirring with a rubber spatula, add the flour mixture to the ricotta mixture and mix just until combined. Set aside for 5 minutes.
Heat a large (12-inch) saute pan over medium heat. Pour in a tablespoon or two of the clarified butter and heat until the butter sizzles. Stir the batter with a rubber spatula. Using a standard (2 1/4-inch) ice cream scoop, drop level scoopfuls of batter into the pan and allow them to cook for a few minutes, until bubbles appear all over the top. While the pancakes cook, distribute the figs on the pancakes, then turn to cook on the other side, until they spring back when lightly touched. Repeat with the remaining batter, adding clarified butter to the pan as needed. Transfer to plates, sprinkle with lemon zest, dot with butter, and drizzle with maple syrup. Serve hot.
