The rhubarb plants at Rabbit Hill this year are magnificent. The white, frilly blooms are nearly seven feet tall, and abuzz with tiny, native pollinators. Against a backdrop of stately spruce, the view is not unlike a scene from a Monet painting.
Surely this was why rhubarb was once grown solely as an ornamental.
Rhubarb in full flower is my reminder that it needs to be harvested, processed, and enjoyed as products from the kitchen. Ruby juice, rhubarb sauce, ketchup and chutney, and of course, tempting and tasty baked goods, like pies, cobblers, muffins and cakes.
Because our crop of rhubarb here at the farm often yields over 100 pounds, I’m always the collector of recipes. And when I tasted Arlene’s Strawberry Rhubarb Coffee Cake, she was happy to share the recipe.
Arlene Wusterbarth is a beautiful baker and a dedicated, community volunteer. She bakes every week and delivers her delicious goods to the Community of Christ Church. Seniors enjoy her treats in Healthy Island Project’s programs like Lunchbox, that delivers 125 meals to seniors weekly, and Coffee Socials, which offers seniors the opportunity to both socialization and get computer tech help. Tender muffins, delicate cakes, and scrumptious cookies, everyone looks forward to whatever Arlene bakes.
“My mother was a baker,” Arlene explained to me. “She always had a dessert on the table. And I raised four children, and really enjoyed baking for them.”
One bite of Arlene’s Strawberry Rhubarb Cake and you’ll be addicted. The crumb of the cake, the bright red, tart filling, and the buttery crumb topping…just sinful!
This is a cake in which attention to detail is important. There are several steps and bowls before it is all assembled and ready for the oven. The first time I prepared the recipe, it was hard to judge when the cake was done as the filling was so juicy. Arlene and I concluded that is was because I had used frozen berries, instead of fresh, which had more juice.
This fruit-infused and buttery cake is rich, and meant to be savored with a nice fresh cup of coffee or pot of tea. One piece was enough for my husband and me to split for our morning break. As always, teenagers and younger, active folks can always consume more.
Maine is fortunate to have wonderful folks and volunteers like Arlene who are the many vital threads of what makes our communities. And now we all can enjoy the satisfying taste of Arlene’s Strawberry Rhubarb Coffee Cake. Quintessential summer: sweet and way-too-short.
