Heat oven to 350°.
Grease the bottom and sides of two bread pans. [I prefer glass/pyrex for sweet breads.]
In a large bowl or in a stand mixer, beat sugars, oil, and melted butter until combined.
Add eggs and beat well.
Add citrus juice, zest, and cognac, and stir until combined.
In a medium bowl, combine flour, baking soda, salt, cardamom cinnamon, nutmeg, and poppy seeds.
Add small, alternating batches of flour and buttermilk [or water] to the sugar mixture, beating until combined.
Add pumpkin and beat until combined.
Pour into prepared bread pans.
Bake for 60-65 minutes or until a knife inserted into the centre of the loaves comes out clean.
Cool in pans on wire racks for 20 minutes.
Remove from pans and cool completely.
Slice and serve.
