A Better Bit Of Batter

Time to make crumpets again today - what else are cold winter afternoons for, after all?
And while we're waiting for the batter to rise, we can practice that well-known tongue-twister:
Betty Botta bought some butter;
“But,” said she, “this butter’s bitter!
If I put it in my batter
It will make my batter bitter.
But a bit o’ better butter
Will but make my batter better.”
Then she bought a bit o’ butter
Better than the bitter butter,
Made her bitter batter better.
So ’twas better Betty Botta
Bought a bit o’ better butter.
