gluten free sourdough starter notes; day 3
Something silly about me is that the idea of fermentation really freaks me out because I am terrified of alive bacteria and mold and fungi, which my brain lumps together for some reason. Terrified. I cannot deal with mushrooms, for example, unless I’m hiking and see them in the woods. This fear doesn’t make any sense but I still have it. Like, I learned about the bacteria in yogurt and did not eat it for 4 years. I still have to actively block out my knowledge of cheese and yogurt. I was only recently able to start eating pickles. Blue cheese, Sauerkraut, and Kimchi all freak me out. This is silly and I am actively trying to get over it. It took me a while to become alright with the idea of making sourdough due to this, but the allure of being able to cheaply make my own bread instead of paying a ton of money for gf bread from the farmer’s market or store was so powerful I decided to try and over come my fear (prompting friends and my partner to be like omg so proud of you--that’s how bad my phobia is). My rough understanding of sourdough is that it is not like cheese, it is different because yeasts are feeding on the flour rather than the flour molding (???). If I am wrong please do not tell me! So I have been reading about sourdough for a fuller understanding, esp. about different yeasts types.
This brief article suggests that the diversity of sourdough microbial communities cannot be explained by location--and here’s another article talking about how microbial communities in sourdough are also on bakers’ skin biodome. But both articles are talking about gluten flours (wheat, rye, etc). I was wondering if there are specific yeasts attracted to rice flour, but this Serious Eats article suggests that the flour doesn’t matter as long as it converts into the right kind of sugar for microbial production. However this Scientific American article says a lot of yeasts come from the flours itself and the flour determines the flavor, I guess because of the yeasts and lactic acid bacteria (LAB) attracted to the flour/attached to it?? Hm! If this works out maybe I will also try a sorghum flour starter.
The Serious Eats article says that the lactic acid bacteria (LAB) in sourdough are also at work in pickles and sauerkraut and kimchi! so I need to get over myself!! 😭
I started my gf sourdough starter, Jonathan, 3 days ago. A baker once told me to bring my mix of flour and water outside and walk through a field to attract wild yeasts so I took my starter out into the yard and took a lap around. I’m using brown rice flour based on this recipe. I also have been tying a dishtowel over the quart jar I’m using instead of using the lid. I am storing it on the top of the fridge for temperature reasons.
I was a little concerned about the starter working because I chose to use tap water and the recipe advises to not do this b/c most tap water has chlorine, which impedes the growth of the starter. However my city has some of the best tap water in the world, so I ignored this. It’s working out quite well. I’ve been feeding Jonathan 50 g of brown rice flour & 50 g of water twice a day. By last night there was some sort of liquid on top--it is possible this was hooch? The recipe says hooch forms when the starter is “hungry” so I am wondering if 50 g of flour is not enough. I hope to start switching to 100% hydration feedings (1:1:1 ratio of starter/flour/water) soon.
By this morning at 7:30 the starter had almost tripled in size and was light and springy with a lot of bubbles. The recipe advises to start discarding today. There’s still some bad bacteria in the mix since it’s only 3 days old so I can’t use the discard for anything yet. It definitely smelled sour.
I am going to try to make sourdough with this recipe. I will start with the suggested flour mix and boule shape. I am fascinated by the idea of using psyllium husk as a binder/gluten replacement. I haven’t used it before; these days I mainly use flax egg as an egg replacement. My research suggests psyllium husk is very popular with the gf sourdough community right now. Since it’s a literal husk (the recipes I’ve consulted do not advise using psyllium husk powder) I’m a little concerned about how it will mix in with the bread. I’m hoping I can start experimenting with the bread itself after I’ve had the starter for about 2 weeks.
