My Starter isn't rising enough and it's an over 100 year old starter..... Help!!!!
I got a starter from my mom that has been in the family for over 100 years (My grandma's mother started it and my grandmother will be 91 this year). In other words it's a good starter and I shouldn't be having problems with it!!! But because I didn't pay enough attention as a child I'm paying for it now. At night when I feed my starter it seems as if it's not raising enough. It doesn't double in size. In a gallon jar it should be going up about 5-6 inches but it's only going up about 1 inch in an 8 hour period. So I figured I wasn't feeding it enough flour so I made it "thicker" but it's still not helping. I need help what should I do.... Can I add anything to the starter to help kick start it??? There's obviously still yeast there just not enough. Help!!!!
Thank you everyone for the comments but I finally figured out what I was doing wrong. I just wasn't saving enough starter for how much flour and water I was adding. It's doubling and bubbling just fine now thank you again =D
