Instructions
Grease a 9x5 inch loaf pan generously with softened butter. Line with parchment, then grease parchment with more butter.
Preheat the oven to 400 degrees F. You are going to turn down the heat to 350, but the goal is to start in a very hot oven.
Whisk the eggs in a bowl or large cup, then whisk in the milk, vanilla and lemon juice. Set aside.
In a large mixing bowl, stir together the flour, baking powder, salt, cinnamon and cardamom. Stir for a minute so that everything is uniformly blended. Grate the butter over the flour mixture and stir until butter coats the flour and mixture is crumbly.
Add the lemon zest, berries and nuts to the dry mixture.
Pour the egg mixture into the dry mixture and stir with a heavy duty scraper until evenly blended. This will take a few minutes. Be sure to get all of that flour blended in. The batter should be grey with blackberry streaks and tiny lumps of butter. Basically, the ugliest quick bread batter you've ever seen.
Scrape the ugly, lumpy the batter into the loaf pan, Stick a few more blueberries or whole walnuts in there, then sprinkle the additional 2 teaspoons of sugar (you can use more or less) to help create a shiny finish.
Bake for 12 minutes and 400F, then turn down the heat to 350F.
Continue baking at 350 for another 1 hour and 15 minutes or until brown and cracked on the top.
Let cool for at least a half hour, then remove from pan and let cool completely.
