Gluten Tag,

I'm Hendrik - a passionate sourdough nerd with a mission to enable everyone around the world to bake delicious bread at home.

I’m obsessed with understanding the science behind each recipe, and the name theBread.code(); originates from my background as a software engineer. My goal is to democratize baking by showing people that you don’t need expensive tools to make amazing bread. With the right techniques and knowledge, anyone can bake great bread on a budget, because I believe bread around the world can always be improved.


The Bread Code

Do you speak Starter? 🫙
7 things your sourdough starter is trying to tell you. Swipe through all the images.

glub. = Not dead. Parmesan. Stir me back in.
BLOOP! = That wasn't me. Give me 7 days.
BLUB BLUB! = NOW. Bake with me now.
pffff. = You're late. Use half as much of me.
fzzzt. = Nothing bad. Want me milder? Make me runny.
blub. = I'm rye. I don't do doubling.
hic! = I'm stiff. I always smell like a party.

Which one did your jar say this week? Tell me in the comments.

Gluten Tag. Same recipe as yesterday but this time the 60 hour sourdough edition. In love with the symmetry 😂. Never felt more German.

Sandwich bread in 3½ hours 🍞

Today is World Bread Day, and this is a loaf you can still bake today. Start it after lunch and it's out of the oven before dinner.

Sourdough is my default. When I need bread the same day, I use fresh yeast:

800 g bread flour
200 g whole wheat flour
650 g water (65 %)
20 g salt (2 %)
20 g fresh yeast (2 %) or 7 g instant yeast

Mix everything. Bulk 2 hours at 22 °C with one stretch and fold, until doubled. Shape, put it into a lidded loaf pan (mine is 34 × 13 × 12 cm) and proof 30 minutes. Bake 1 hour at 200 °C with the lid on.

Swipe for the recipe as a flowchart. On Loafy you can bake it step by step with free timers: loafy.ai/bake/22rSw8VNSqEnB2KwKCo3CFCk

Log any loaf in Loafy by Sunday and your country lights up on the World Bread Day map.

Sourdough or yeast for your sandwich bread? Tell me in the comments.

Happy Baking.

What's the max amount of yeast you ever used to make a dough? Sometimes it has to be fast and I use more yeast to make the dough, but I feel bad 😁

The Sourdough Thermometer 🌡️

12 temperatures every sourdough baker should know, from the fridge to the oven. Swipe through all six images.

A few that surprise most bakers:
• 4 °C: fermentation pauses, so your dough can wait up to 24 hours
• 60 °C: yeast and bacteria die
• 92 °C in the core: your bread is done
• 118 °C: acetic acid boils, but the steam already carries it off earlier, mostly from the crust. That's why a dark bake or toast tastes less sour.
• The crumb never gets hotter than about 100 °C

Which one surprised you? Tell me in the comments.

All numbers come from my free book The Sourdough Framework.

Happy Baking.

Baking season is back - what's the type of bread you bake after taking a break?

I opted for a free-standing bread made overnight with little % of starter. Turned out great 🙏.

Gluten Tag. Just shipped a pizza calculator update (also my default sourdough calculator by the way). For pizza you can now simplify shopping and see exactly how much mozzarella and sauce you should purchase. The basic calculator is a bit basic 😂. Link in comments.

I’m excited for a warm, down-to-earth chat with Mike and to learn from his expertise. Now I want YOU to be part of the conversation - what would you ask Mike about sourdough baking, fermentation, or home cooking? Drop your technical questions or curiosities in the comments, and we might ask a few during the interview!
