Are lilacs edible?
Lilacs are totally edible, part of the olive family. And we have some favorite ways to enjoy them. If you have the opportunity, spend a very beautiful day hand-plucking each individual flower off their stem and soak them in a bath of cream to let the flowers infuse into a floral milk for the cake and buttercream. The precious liquid can then be turned into creamy and dreamy lattes, buttercreams, like for our lilac cake and lilac ice cream. Or infused into a floral sugar, like lilac brown sugar. Or preserved in a raw local honey, like in this lilac honey recipe.

If you haven't tried baking with flowers before, this is the perfect place to start. Once you try you will be so pleasantly surprised with the outcome you'll want to make them over and over again.

Frequently asked questions:
Should you sift flour when making shortbread?
We recommend sifting flour for all baked goods to break up any clumps. It’s especially a good idea in this in a recipe like this that has such few ingredients. However, if you don’t have a sifter, you can skip this step.
Why is my shortbread too soft?
Shortbread contains a high amount of butter, so if you find your shortbread too soft, try chilling the bars before baking. This will allow the butter to harden.
Do I need to poke holes in my shortbread with a fork?
Forking shortbread is not necessary, but it prevents the butter from bubbling. Pricking your shortbread also gives it that signature Scottish shortbread cookie design!
How should I store shortbread cookies?
Because shortbreads have a high fat content, they must be handled carefully to prevent crumbling. To store, arrange your cookies in a single layer, adding a piece of parchment or waxed paper between layers.
How long will shortbread last?
Shortbread cookies keep longer than most other cookies, making them perfect for edible gifts or when you need to make something ahead. They even taste better the next day or two after you bake them! They will keep in an airtight container at room temperature for up to 3 weeks or in the freezer for up to three months.
