On the day 3 of making our sourdough starter you should barely notice any bubbles or unusual activity in your starter. If you see lots of bubbles just ignore it and continue on with the feeding as shown in the video bellow. Because of inadequate pH level int he mixture some other than yeast bacteria may temporarily take over- and may look like you got a good starter because of many bubbles. Generally it would be too soon to achieve a vibrant enough starter to use in a recipe. Don’t repeat my mistakes! You really need to be patient for another day or two to see the proper results. Enjoy and as always, ask you questions in the comments below the video.
