Preheat oven to 350°F with a rack in the middle of the oven. Grease a 9x5 loaf pan and set aside.
In a medium bowl, combine flour, baking powder, and, salt.
In a separate bowl, using a stand mixer fitted with the paddle attachment (preferred) or a hand mixer beat butter, sugar, and lemon zest on medium speed for 3-4 minutes, until light and fluffy. Add the eggs, one at a time, beating well between each addition and scraping the sides and bottom of the bowl and beater as necessary. After both eggs have been added beat in the almond extract.
In a liquid measuring cup combine the buttermilk and lemon juice.
Alternate adding the dry ingredients and the buttermilk into the butter mixture. Add one third dry ingredients, beat until almost combined. Add half buttermilk, beat until almost fully combined. Follow with half of the remaining dry ingredients, the remaining buttermilk, then the remaining dry ingredients. Beat between each addition until just combined and scrape the bowl and beater as needed. Once everything has been added, beat the whole mixture on medium-high speed for about 15 seconds.
Pour batter into prepared loaf pan and smooth the top. Bake for 45-55 minutes, until a toothpick inserted into the center comes out clean (be careful not to overbake). Rotate the pan halfway through bake time to ensure even browning. Place the pan on a rack to cool for 15 minutes. Proceed with the syrup.
