Rhubarb season is here. Time for some Rhubarb cake, muffins, and Rhubarb strawberry pie. With the fresh produce now coming into the Calgary Farmers Market I’m back to my weekly shopping trip on Friday morning to see what I can load up on. The Innisfail growers had hanging strawberry plants and lettuce gardens available, so those items were purchased first.

I’m keeping my lettuce garden on my kitchen counter,  it’s great to pick off fresh lettuce for salads. The strawberries are getting ate every time someone goes outside which I love. I picked up my usual variety of organic tomatoes, cucumbers, peppers and was ecstatic to see that Rhubarb stalks were available.

Rhubarb technically is a vegetable with a rich tart flavor. It’s a low calorie vegetable full of fiber, anti-oxidants, minerals and vitamin A and B. Rhubarb’s nickname is “pie plant”.
I’ve been adapting some of my old recipes to gluten free using Cup4Cup gf flour mix and thought an old fashioned rhubarb sheet cake would be up for the challenge.
