What is rhubarb?
Despite being used in many sweet applications (like my Strawberry Rhubarb Pie,) rhubarb is actually a vegetable!
It looks like large stalks of red celery.
The stalks of rhubarb are edible, but the leaves are not!
The flavor of raw rhubarb is similar to a super sour and tart green apple while having the texture of celery.
It’s commonly found in the spring and summer months at most major grocery stores and farmers’ markets.
If you can’t find fresh rhubarb, frozen rhubarb can be found in your grocery store’s freezer section!
Variations and additions
Crisps are perfect for adjusting to your tastes and dietary needs.
If you need a gluten-free version, just swap out the all-purpose flour for a gluten-free variety!
Looking for a dessert with no added sugars? Swap out the sugars for your favorite sugar alternative.
If you’re looking to add some crunch, add some chopped walnuts or pecans to the oat topping!
