Add roughly 50g of flour to feed your starter (you want 100g of active starter for the recipe, so it depends on how big you keep your starter (say you may want to feed it for a couple days without discarding if you keep a small one going)(or if youâre taking yours out of the fridge youâll def need to do one feeding before itâs strong enough to bake with).
Add enough spring water (you donât want filtered, you really do want the added minerals) until the dough resembles a thick pancake batter. Generally 50g of water/50 g of flour (i.e. a 100% ratio) is enough to get the consistency right (but if you're dealing with warmer temperatures you may want to do just 70% to have a more stable starter).
Allow to rest for 3-6 hours in a warm(ish) place: until it doubles in size. You can test for prime activity fairly well either using the float test (as it sounds: check if your starter floats in a little water) or the burn test (tap your starter on the counter to âbreak the surfaceâ, light a match and if it blows out it means your starter is using up all the oxygen in the surrounding area i.e. itâs sourdough time).
3-6 hours later: make your dough
Add the water (preferably at room temp), pumpkin puree, active starter and honey to a large bowl. Using your hands (though some peeps favor a danish hook) mix until thoroughly dissolved.
Add in the flour and salt and mix with your hands until just combined and the dough is all shaggy (and sticky).
Cover with a kitchen towel and let it rest for 30 minutes.
30 mins later: bulk rise (plus stretch ân folds)
Thirty minutes in youâll want to do a set of âstretch ân foldsâ: grab a hold of the dough, stretch it upwards and fold it down towards the center of the bowl. Rotate and repeat four times (you can watch me do it here).
Repeat three more times every thirty minutes (sourdough pumpkin baked goods take a little longer to develop gluten, so its important to do a few sets!).
Transfer to a smaller bowl (as itâs easier to gauge the rise if you can actually mark it with a sharpie) and cover with a kitchen towel.
Allow to rest for 3-10 hours, or until at least doubled in size (remember that time here is directly influenced by temperature so itâll vary greatly)(p.s. I generally let mine go until it almost tripes as Iâve pushed it just until the point that it begins to recede back and it still comes out superb)(and I personally find it easiest to digest).
4-8 hours later: shape
See post for guidance! Lightly flour your working surface, turn the dough out and stretch it out gently (allow it to rest for 10 minutes if it âfeelsâ like itâs resisting)(youâll know, trust me!). Stretch it out, sprinkle with cinnamon sugar, fold the sides in, and roll it gently but tightly. You then want to roll it gently against the counter towards you a few times (this creates surface tension, making for a better crust!).
Transfer to a (very well floured or lined) banneton or small-ish bowl and cover with a paper towel, place inside a plastic bag and refrigerate for 6-24 hours (sourdough breads with added starches and sugars can't really go much longer than 24 hours)(I did 48 once and it was ok, but a little too sour).Or allow to proof at room temperature for about 2 more hours, until it springs back to touch (you literally want to poke it gently, and if it springs back you know youâre golden)(though if it springs back too quickly itâs actually under-proofed)(and, you mayâve guessed it, if it doesnât spring back at all youâre now over-proofed). i.e. this is why baking a few loafs and poking them around throughout itâs stages is highly suggested.
2 hours later: bake away!
Preheat oven to 450°F/230°C with your Dutch oven inside for 20 minutes (some peeps bake at a lower temperature, say 420°F, it depends a bit on your oven).
Wrap loaf with bakers twine and score it (please see video story for a little tutorial).
Bake lid on for 20 minutes, remove lid and bake for 20 more minutes or until deeply golden brown (if you tap it on the bottom itâll also sound hollow).
Allow to cool completely if you want it at its bestâ but 20 minutes will do if you simply canât hold your horses (and you donât want to wreck your crumb).p.s. my best suggestion for storing your sourdough is to simply keep it in your bread or Dutch oven (what I do). But investing in a bread tin is neat too!
Notes
*please note that all sourdough recipes on the site are developed around King Arthur's Organic Bread Flour (for consistency sake)(and because its my personal favorite "generic" flour to bake sourdough with)(but I generally also test all the recipes with other heirloom & heritage floursâ Hayden Flour Mills makes some of my favorite blends).Â
