I’m away from home now, but if you remind me next week I could share the exact recipe I used :) I’ve been following a Swedish book by Kenny Jakobsson for both the sourdough and the pizza. (It’s a nice book, but it’s written from the perspective of a much warmer kitchen than what I have, so everything takes quite a bit more time) There’s a lot of recipes online as well, but I found it helped me with a physical book with such a long term project.
