Method:
In a medium bowl, whisk together flour, sugar, baking powder and salt. In a large bowl, whisk together ricotta, eggs, milk, zest and vanilla. Add dry ingredients to wet ingredients, stirring just until combined. Stir in strawberries.
Heat oil in a large skillet or on a griddle over medium heat. When hot, drop the batter by 1/3-cup measures onto the skillet, working in batches so you don't crowd the pan. Cook until the bottoms are browned and bubbles begin to form on the tops, 3 to 4 minutes. Flip and cook the other sides. Continue cooking until all the batter is used, making about 12 pancakes; add more oil to the pan as necessary to keep pancakes from sticking. Serve pancakes garnished with more berries.
