My grandma's handwritten recipe for sourdough starter from 1978 worked on the first try, but my phone app failed three times. | Forgotten Skills Revival - Talk Freely
Grandma's notes are always the best tech. My mom's old cookie book has stains and notes that work better than any blog recipe. Those old handwritten tips just have the magic touch.
Honestly @mary372, have you ever tried a recipe blog that actually tests their stuff? Some of those sites fix all the old mistakes grandma never caught.
