Preheat oven to 450
1 cup of pureed squash
2 tsp sugar
11/2 cups of milk
1 package of dried yeast dissolved in 1TLB of warm water
31/3 to 41/3 cups of bread flour. You can substitute some whole wheat here but the bread will be heavier.
Scald the milk, then mix in the pureed squash, butter, sugar and salt. When this mixture cools to lukewarm add the yeast and enough flour to make a soft supple dough. It should be slightly tacky.
Knead well. (My mother used to say that a well kneaded dough should be as soft and smooth as a baby's bottom. As funny as that sounds it's actually a perfect description)
Let rise until doubled in bulk. Punch it down and shape your loaf. Place in a well oiled bread pan that has been sprinkled with a little cornmeal of whet germ, and let sit in a warm place until it is well risen over the top of the bread pan.
Place in the oven to bake lowering the temp to 425 after the first 15 minutes.
