Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line it with parchment paper.
Chop the strawberries and separate about 3 tablespoons of them. These will be used to press into the dough prior to baking. (If doing a long fermentation, hold off on chopping strawberries until ready to bake.)
Place all the strawberries to the side.
️In a large bowl, whisk together the fresh milled wheat flour, baking soda, baking powder, and salt.
️In a separate bowl, mix the sourdough discard, sugar, melted butter, eggs, vanilla, lemon zest, and buttermilk. Stir until well combined.
Gently fold the wet ingredients into the dry ingredients, being careful not to overmix. (At this point the dough can be covered and placed into the fridge until the next day for a long fermentation. See notes.)
Add the chopped strawberries to the batter.
️Fold in the diced strawberries until evenly distributed.
Pour the batter into the prepared bread pan and smooth the top.
Press the reserved chopped strawberries into the top of the dough so that the red skin is showing.
Bake for 40-50 minutes, or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
While the bread is cooling, combine the powdered sugar, lemon and milk.
After the bread has cooled, drizzle the glaze over the top of the strawberry discard bread.
Slice and enjoy!
