5 half-pints of blueberry butter
Source: Source: Tree Ripe Citrus
Recipe: Blueberry Bonanza, p. 60, Ball Complete Book of Home Preserving, 2006
Notes: 2 half-pints left from 2011; used three Tattler lids and two regular lids; two Tattler lids did not seal. When I reviewed the Tattler box, it recommends fingertip tight before processing and then fully tighten when removing jars from bath.
