I'm not one of the pro's; but you're welcome to try this if you like:

227 grams each wheat flour, malted barley flour, rye flour, whole grain rye flour  (total 908 grams)

300 grams warm (100 - 110 degree) water

115 grams vinegar

18 grams active dry yeast

15 grams salt

1 Tbsp caraway seed

1 small onion, finely chopped

115 grams granulated sugar

In food processor, combine onion, caraway seeds and 60 grams of the water.  Pulse just until fully combined. 

Mix vinegar with equal amount of water to dilute.  Add to the onion, caraway seeds, salt mixture

In large mixing bowl, combine salt, sugar and flour.  Whisk to combine well.  Add the yeast and whisk briefly to distribute evenly

Mix with paddle until dough forms into ball and pulls away from mixer bowl sides.  Add water or AP flour as needed to create a slightly tacky dough.  It should not stick to your fingers.

so much as to pull away from the formed ball when pressed with fingertips.

Replace paddle attachment and introduce dough hook.  Knead, mediium speed, 10 - 12 minutes or until dough is smooth and elastic.

Place dough in oiled bowl at room temperature (70 deg. or above) and cover with tea towel; allow to rest until double in volume.

Remove from oiled bowl and divide into two loaves.  Shape each loaf on parchment paper dusted with corn meal.

Lightly spray top of loaves with oil and cover with plastic wrap.  Allow to rest at room temperature until double, or nearly double, in size.

Bake until linternal temperature reaches 195 degrees (This may take 40 minutes to one hour   -  watch it closely so it doesn't get too brown)

Remove to cooling rack and allow to cool for minumum of one hour before slicing.
