I baked a loaf or rye bread today, that I started yesterday with a sponge made with half barley flour and half rye, soaked about 18 hours. It was made of 2/3 c barley and about 2 c rye, so it was relatively low in whole wheat, which I think ended up only around 1 2/3 c. I added a little wheat gluten, but it fell a little when baking, and the bread will be a little dense, but it will still be delicious, I'm sure.

This time it was a similar bread, that started with a sponge with some rye and barley flour, with a tb each of caraway and instant yeast and some water. It sat on my counter for 3 days. I was making these outside on my grill, since I don't like to turn the oven on in this heat! Or any kitchen heat, for that matter! First, I made the chicken I was going to marinate, to grill after the bread, and put that in the fridge, then made the bread. I added the sponge, some essential gluten (since I had so much rye flour), a little brewer's yeast, blackstrap molasses, oil, a tb of salt, 2 more tsp of yeast, another tb of caraway, 2 c water, and 4 c of whole rye flour, then mixed it all up with the bread whisk, then put the bowl on the mixer, with 2 c WW flour, and set it to mix with the dough hook on 4 for 6 minutes. This was fairly quick, since this time, with the hydration being perfect, once the "kneading" started - no extra flour needed (what usually happens), so it was all whole grain, and not too dry.

The bread didn't keep much of the height, but that's normal, with a bread using that much rye, compared to WW. Only added 1/4 c gluten - could have used more.

I made another one of those breads I put some barley flour in, partly because I only had about 3/4 c rye, and partly to use up the 3/4 c of barley flakes, which made about 1 c of flour. The rest was whole wheat, and fortunately, I didn't have to bake them outside. I made this loaf of bread today, to make sandwiches with - something to snack on, when I start all baking all those cookies. Those get started tomorrow.

I made a batch of WW, potato, barley, and rye bread yesterday - started it Saturday, when I milled that rye flour. I started by making a sponge with some mashed potatoes, about 1 1/3 c (using flakes - they're good for this!), the last 3/4 c barley flour, and 1½ c rye flour, about 1¼ c additional water, and 2 tsp yeast. About 24 hours later, I added the remaining ingredients - 1 c water, 3 oz blackstrap, 2 oz oil, 1/2 c wheat gluten, 2 tb brewer's yeast, 2 more tsp instant yeast, 1½ c rye flour, 2 c WW flour, mixed to a sticky ball, then let it sit 15 min, for the whole grains to absorb the water. Then I added 2 tsp salt (I always put this in, before I cover, so I can't forget it), and start mixing in with the dough hook, and add bread flour, just until it's the right hydration - sticking to the bowl a little, but still pulling away. Only took about 3/4 c of the bread flour. Then I sprayed it with the baking spray, and rolled it in the bowl, and covered for 15 minutes, in between the 3 "folds", and then let it rise about 80 min. Got 2 pans ready for 2 lb loaves, shaped the loaves, and after rising about an hour, baked them 40 minutes in the convection oven, on 300°.
