Food Processor Pound Cake

Directions

1. Adjust the oven rack to middle position and heat oven to 350° F (adjust for convection according to the instructions with your oven). Grease and flour a 8 1/2 by 4 1/2 inch loaf pan, or line the bottom and all four sides with parchment. (You can use a 9 by 5 pan, but check for doneness 5 minutes early)
2. Put the sugar, baking powder, salt, eggs, and vanilla in the bowl of a food processor and process for about 10 seconds until totally blended. With the processor running, add hot melted butter in a steady stream until incorporated. Scrape the mixture into a large bowl.
3. Sift flour into the bowl in three additions, whisking just until most of the flour is blended after each addition. After the last addition whisk until just until there are no visible lumps or veins of flour (do not over whisk).
4. Scrape the batter into the prepared pan. Bake until a toothpick inserted in the center comes out nearly clean—with few crumbs clinging to it, 50 minutes to 1 hour.
5. Let the cake cool in the pan on a rack for 10 minutes. Slide a thin knife bade around the sides to detach the cake (or lift the parchment liner) and remove the cake to the rack to cool completely, about 2 hours, before serving. Cake may be wrapped and stored at room temperature for 3 days, or frozen for 1 month. Thaw at room temperature without unwrapping.
6. VARIATIONS .
7. Lemon or Orange: Grate the zest of two medium lemons or a large orange directly into the food processor and add 2 teaspoons lemon or orange juice, before adding the sugar etc.
8. Toasted coriander with cardamom and cinnamon: Add 1 1/2 teaspoons ground toasted coriander seeds*, 1/2 teaspoon ground cinnamon, and 1/2 teaspoon cardamom seeds that have been finely crushed in a mortar (or not-to-finely-ground in a spice grinder) to the hot butter, cover and let steep for 10-15 minutes. Reheat butter if necessary before adding it (with the spices) to the batter as directed. *Toast whole coriander seeds in a dry frying pan over medium heat, shaking the pan, until then are golden brown and fragrant. Pour onto a dish to cool. Grind in spice grinder or crush finely in a mortar.
9. Brown Butter: Add 1 1/2 tablespoons of water and an extra pinch of salt to the food processor with the sugar. Use hot browned butter in place of the hot melted butter.
10. Brown Sugar (with or without nutmeg): Replace half of the sugar with dark brown sugar and add an extra pinch of salt. If desired add 1 teaspoon freshly grated nutmeg to the hot butter, cover and let steep 10-15 minutes. Reheat the butter as necessary before using as directed.
11. Buckwheat: Swap one quarter of the cake flour (6 tablespoons/42 grams) for an equal weight (42 grams/5 1/3 tablespoons) of buckwheat flour. Proceed as directed, adding the cake flour in two additions and the buckwheat flour last
12. Vanilla saffron: Split a vanilla bean and scrape the seeds into the hot butter. Drop the pods into the butter as well. Add a scant 1/8 teaspoon crushed saffron threads. Cover and let steep 10-15 minutes. Remove the vanilla pods. Reheat the butter if necessary before using as directed.
