Blueberry recipe contest winner: Kennewick girl’s dish has international flair

Katherine Cooper's blueberry recipe has French and German influences.

A creative and talented teen chef has won the kids’ recipe contest (we told you about it here) sponsored by the Washington Blueberry Commission.

The winner is Katherine Cooper, 15, of Kennewick, a student at Hanford High School. She created and baked a Blueberry, Lemon and Lavender Entremet Cake.

There is an interesting story behind Katherine’s recipe:

“I had just come back from a cross-state road trip and had met a baker from Munich. She had learned French baking styles and combined it with a Munich style,” she explains. “She helped inspire me to include more of a French touch in my baking. With this inspiration, I decided to make an Entremet Cake using a lavender cake, lemon mousse and blueberry jelly.”

If you aren’t familiar with the term “entremet,” we did a little research. It literally refers to a sweet course in a multicourse meal, generally following the cheese course (fancy!) However, in baking practice, it is a multilayered, mousse-based dessert with varying flavors and textures.

Katherine says she has “always looked forward to blueberry season when I can have blueberries in my pancakes, coffee cake, waffles and muffins.”

After winning this blueberry recipe contest, she can stay busy in the kitchen because her prizes are a flat of Washington blueberries and a DIY kit from Trophy Cupcakes.

Judge Sadie Davis Suskind, an accomplished young chef herself, said this to say:

“Before even reading through your recipe, I was amazed by your professional plating skills. You structured your entremet with elegance and style! The recipe itself seemed carefully crafted. I so appreciate how you took the time and effort to build the different components of your dish from the blueberry and lemon fillings to the cake to the lemon curd and the blueberry glaze. Outstanding dish, Katherine!!”

Katherine shared her recipe, which we’ll print below.

We previously shared a recipe from Sadie for a buttermilk panna cotta with blueberry compote.

The blueberry folks also have a bunch of kid-friendly recipes (some quite simple!) In addition, they have a list of places to get berries. Finally, we have listed some of our favorite u-picks.
