This year I experimented a bit while baking gingerbread cookies. 
I cut out a circle in the middle of each flower. I placed a hard candy in the circle and baked the cookies. The candy melted and formed a pink center.
When the cookies had cooled, I piped white decorations. Easy and fun, and the kids love the cookies!
And I love this – being able to have a hyacinth at home! I am usually too allergic to stand their fragrance, but nowadays I feel so much better that I can finally have some natural Christmas scent around!
