For any rhubarb newbies here, let’s start by answering all your rhubarb questions!
What is Rhubarb?
Rhubarb is a stalky vegetable with a similar texture to celery. It has a tart flavor and is usually baked like a fruit in cakes, pies, and crumbles.
When is rhubarb in season?
In the United States, rhubarb season is typically April through June. However, in the Pacific Northwest, rhubarb has peak flavor and texture all the way through July!
When in season, the stalk is crisp and the flavor is tart.
Do I need to peel rhubarb before cooking?
As long as the skin is thin and rhubarb is in season, you do not need to peel rhubarb.
What does rhubarb taste like?
Rhubarb is thick and juicy and has a tart taste. It is usually dipped in sugar or a sweet substance if eaten raw, or used in a sweet baked good where sugar or other fruits balance the tart flavor.

Can you replace the coconut butter with a vegan buttery spread?
Jamie
Hey Aurora! I haven't tried it myself but I think a vegan buttery spread will work well in place of coconut butter. Let me know how it turns out!
