Makes one loaf
Preheat oven to 325 degrees
Steam carrots and let cool down a bit. Mash them with your mixer until fairly smooth. Set aside.
Combine ½ cup softened butter, sugar and eggs and mix until well blended. Add the mashed carrots and beat them into the batter.
In a separate bowl, whisk together the flour, flax seed, baking soda and cinnamon. Add this mixture to your batter along with the 1/3 cup of warm reserved liquid. Beat on medium until well combined.
Stir in walnuts and raisins.
Lightly butter your loaf pan. I use a metal pan. Spoon in the batter and smooth out the top.
Bake on 325 for about one hour. Test by inserting a toothpick. It is finished when it comes out clean.
