Step 1

Preheat the oven to 350ºF. Grease a 9- or 10 x 5 x 3-inch loaf pan (see notes above!) with butter (grease it very well). In a medium bowl, combine the flour, baking powder and salt. Stir to blend.

Step 2

Using a mixer, cream the butter, ricotta and granulated sugar until blended, about 3 minutes — I never really go over three minutes, and it’s ok if there are some visible pieces of butter. In other words, the batter will not look entirely smooth (see photo). With the machine running, add the eggs 1 at a time. Add the vanilla, zest and lemon juice until combined. Add the dry ingredients, a small amount at a time, until just incorporated.

Step 3

Pour the batter into the prepared pan (Note: Do not fill pan higher than 3/4 — save extra batter to bake off in a mini pan or muffin tin … if you fill the pan higher than 3/4 you risk the batter spilling over. See notes above.) and bake until a toothpick comes out clean and the cake pulls away from the sides of the pan, 45 to 60 minutes (about 35 minutes for mini pans). Let cool in the pan for 10 minutes, then transfer to a rack to cool completely.
