Mix the sourdough, the milk and the fresh yeast in a big bowl.
Add the flour, sugar, salt, egg and butter and knead by hand or a stand mixer on level 2 for about 10 minutes until you have a smooth dough that comes off the side of the bowl.
Cover the bowl and let the dough proof for 1 hour.
If working on a wooden counter, flour it a bit. I work on stone and I find the flour to prevent me from rolling the dough so I leave the work surface blank.
Grease a baking pan.
Divide the dough in three parts. I use a scale for this to get three even parts and the braid looks balanced.
Roll each part into an about 35cm long log. Braid and transfer into the greased pan.
Brush the braid with some cream, cover it and let if raise until it has doubled in size. For me this took about 90 minutes to two hours.
Preheat the oven to 160°C/320°F.
Brush the loaf again with some cream and bake for 35 minutes.
I don't bake with cups, in my opinion, scales are far superior for baking. If you want to use cups, you can find converters from grams to cups all over the internet: https://www.thecalculatorsite.com/cooking/cups-grams.php
If that is the case, what do you suggest I do? Bake many loaves with various conversions until it hits the spot? Why would I? I weigh my ingredients and it works for me. I'm not a service station nor do I make money by posting a recipe here.
Jaryn, Grams are a measurement of weight, measuring cups measure volume, (unless it is a liquid and that is the confusing part). The two are not equivalent, which is why you are finding different website offer different equivalents. Vera K. is correct, in baking, weight is far superior and more accurate than volume. In cooking, not so much. Your best bet is to treat yourself to a kitchen scale, you will be amazed at how much your baking will improve.
