Mary Lincoln Extra Credit Questions

[Anita]

Thanks, Anita - very colorful decoration! I wonder if in Mary's days such was colored, too, probably white-red-blue? White (natural) and red (beetroot juice) is easy, but blue?
PS: Mary would probably have loved these cookies:

Eva, I don't know if Mary's macaroon cookies were colored but it's possible to get a natural blue from blueberries.

And I agree Mary would have loved the cookies on the link you posted. They are gorgeous and I imagine their taste matches their beauty- scrumptious! Have you tasted such delights?
