Synchronicity city

Here's Grandpa Vine.After the previous 2 blogs I was checking out Cream of Tartar on the web,having finished our 20-year-old container the other week making rather tasty pancakes,and finding it hard to come by around here.Turns out that C of T comes from the crystalline [!] acidic deposits in wine-barrels [!],earliest examples found in Iran in pottery vessels [!] from 7000 years ago.Without checking further [I'm going to make a batch of pancakes] it seems to me that baking powder is just soda bicarb [as used in soda firing,by the way] with cream of tartar,so I'll try using that.If you come by in the next day or so,you might even get a taste.
