I’m moving away from white flour toward whole grains. This is my first 2:2:1 whole wheat/rye/white loaf and I’m loving it. The trick is to stick to one loaf per week.

A photo of a fresh whole wheat/rye/white sourdough boule on a cooling rack. It’s our favorite, so far.

White dog doesn’t like carrots. She just likes whatever brown dog has.

Testing different flavors for second fermentation to get some fizz and flavor profiles.

What’s logical thing to do when it’s 90F out? Well, fire up the oven, of course!

First attempt at a 60/40 white/rye loaf. I’m think a bit less time in the oven for the next one.

#fermentation #sourdough #baking
A not-so-bad attempt at a loaf of a white/rye blend sourdough cooling on a wire rack. The outside is a bit burnt.

Moving on to trying my hand with rye and a whole new recipe. So far, so good.

#sourdough #bread #fermentation
A photo of a loaf of sourdough bread in the over after the cover was removed from the Dutch oven. This one is a rye/white flour mix of about 10% rye. It seems to be coming along nicely.

Looks like I’m out of excuses. Time to get to work.

The rack of ribs is done and resting. They worked hard. The final product: sourdough bread cooling in a rack.

I didn’t go to the Cape this weekend because I need to work. How I say, “I’m procrastinating” without saying, “I’m procrastinating” in two photos. Not seen: Prepping for kombucha making and maybe coffee roasting. Nothing like a little self-induced angst.

Last weekend, I roasted Full City and City+ and have started testing my first blend. Not half bad. I just have to dial back the number of tests in a day or they’ll be peeling me off the ceiling.

Working on my home roast technique and understanding the aging process. 7 days off roast and not awful. Decent, actually. I think it’s getting to its sweet spot.

With the bread baked, I’m now onto my next substance of choice and trying to dial in my roaster. Tasting notes in a few days.

Today’s loaf of #sourdough. Getting back into it after a couple weeks off. Time to start working in some rye or spelt. I’m ready.

#fermentation
Yet another loaf of sourdough bread.

There’s a ton of day job-type work I need to get done today, so of course I’m bottling kombucha and roasting #coffee. It’s important to ease into one’s weekend work regimen.

After a 2-week carb load, it’s time to back off the sourdough and get back to my #kombucha. Batch 23 is ready for F2.

Here’s this morning’s loaf and the last one for a while. It’s been really fun learning how to do this, but for a guy who barely eats bread, I’ve been plowing through half a loaf in a sitting.

Today, I went from all-purpose to bread flour and it turned out pretty decently. Reminds me of perfecting martinis at home. “Maybe this isn’t a good thing.”

A photo of sourdough bread on a cooling rack. It’s got a nice rustic bread look to it, if I may.

A neighbor came sniffing around the house this morning. She must have seen my post about the bread.

Second attempt at sourdough and I’m pretty pumped, so much so that I’m working on a song to celebrate. I’ve only got the first line:

“Take me down to Carbohydrate City

Where the bread is hot and the crust is crunchy.”

Maybe I should stick with guitar.

A photo of the crumb of a loaf of sourdough. Is it OK to admit that I’m quite pleased with myself?
