Gluten-Free Rhubarb Muffins with Oat Crumble


There was another wonderful selection of produce at our CSA pick-up last week including a pretty bunch of rhubarb. I have to say the most striking differences between the fruits and vegetables I am used to buying at the grocery store and those I am receiving from Rexcroft farm are size and flavor. Those from my local farm are tiny by comparison however, they are packed with flavor.

The rhubarb stalks I am used to working with are easily 1 – 1 1/2 inches thick. My thickest one from the farm was about 1/2 inch. It’s the same thing with my strawberries. They are teeny tiny compared to the ones I generally buy, even the organic ones, yet incredibly sweet. A lot of the vegetables are small too. Little cucumbers and squash that look like those we might characterize as “baby” normally. They are still full of flavor. The largest items I’ve received are the greens.

It makes you think a lot about what is being put into commercially sold produce which makes it get so much bigger. Whatever it is, is definitely not adding any flavor. If a CSA is not an option for you, I highly recommend shopping your local farmer’s markets when you can. Especially in the summer since there is so much delicious fruit out there right now.

Rhubarb is actually a vegetable. However it was legally defined as a fruit in 1947 by a New York court because it was more often used as one in recipes and apparently tariffs are lower for fruit than vegetables. Who knew? Whatever you want to definite it as, it is a great filling for pies and mixes well with some other fruits like strawberries and blueberries. I wanted to keep it simple today with a muffin recipe you could whip up and eat for breakfast or a midday snack.

I used the new Bob’s Red Mill 1-to-1 baking flour blend. Samples were sent to Bon Appétit recently. One of the editors swung through the test kitchen and dropped off a couple of bags for me to try. I’m pretty happy with it so far. I definitely find it to be more versatile than their other all purpose flour blend which has chickpea flour in it. The 1-to-1 blend worked great in these muffins as well as a batch of cranberry muffins I made in the test kitchen a few days ago. For both recipes, I added some almond flour to give it a little bit of a nutty flavor. Enjoy!
