Sourdough in the Zojirushi Bread Machine

I managed to get a Zojirushi Virtuoso Bread Machine on Facebook Marketplace. So, I have been having fun baking new loaves of bread. I didn't believe it could make real Sourdough bread in a machine, but I was pleasantly surprised! The original recipe: https://www.thefreshloaf.com/node/702... Add to the bread machine in this order: 1 cup bread flour 1 teaspoon salt 1 teaspoon sugar 2 cups active starter 1/4 cup water 1 Tablespoon milk 1 Tablespoon butter diced 1 cup bread flour Zojirushi Custom Cycle times Pre-heat: 30 minutes (this just gets everything to the same temperature) Knead: 18 minutes (you may want to check and add more water if necessary) Rise 1: 1 hour, 30 minutes Rise 2: 1 hour, 30 minutes Rise 3: 1 hour, 30 minutes Bake: 1 hour, 2 minutes Keep Warm: Off
