Why Fingerprint Instead of Thumbprint?
If you use your thumb to make
indentions in cookies, you end up
with a lopsided indention that jam
can leak out from. Using a finger
(or mini bottle top) perpendicular
to the baking sheet means you
have a uniform hole to place your
jam. My neighbor Greta tried these
using peanut butter and Nutella.
PB&J cookies anyone?
