Finally attempted my first loaf !

Finally made my first loaf today with my starter!! I followed this recipe https://foragersofhappiness.com/beginner-sourdough-bread-recipe/#recipe

• 100g starter, 420g water, 15g salt, 600g bread flour
• Mixed dough, let it rest for 30 min, then did 3 sets of stretch & folds over 2 hour period
• Let it sit covered for about 10 hours for bulk fermentation (my home is pretty cold, & I also was a bit confused on what to look for to know when it’s done with BF lol)
• Shaped the dough best I could then put into a floured banneton, covered
• Put in my fridge for about 12 hours
• Baked in my Dutch oven at 450f for 17 min then removed DO lid & baked for another 18 min
• Let cool on a cooling rack for about 3.5 hours before cutting

I’m shocked it turned out the way it did, I was mentally preparing for the worse outcome 🤣 Although, I do wish I left it in the oven for a few more minutes at the end.

I’m pretty proud of it, but would love some feedback or tips on how to improve.
