What is rhubarb?
Rhubarb originated from Asia and was originally used for medicinal purposes before it became a culinary darling. It looks like big leafy celery and tastes like sour green apples. Rhubarb stalks come in a variety of colors ranging from green to pink to dark red. It is technically a vegetable because it does not produce seeds. However, most consider it a fruit because it’s mainly used in desserts.
Is rhubarb poisonous?
Only the leaves are poisonous. They contain a toxin called oxalic acid which can cause health problems when eaten in high amounts. Cases of poisoning are rare because you would have to consume several pounds of the leaves in one sitting to reach the lethal dose of oxalic acid but it’s still best to avoid the leaves. The stalks and roots are edible. The stalks are used for culinary purposes and the roots are used for medicinal purposes. (source: Healthline)
Should frozen rhubarb be thawed before baking?
It depends on the recipe. I normally do because baking from frozen takes much longer and it also releases more water.
Why is my rhubarb crisp runny?
Rhubarb contains a high level of water which can make the crisp runny. Add a touch more cornstarch or flour and that will help make it less runny.
How do you cut rhubarb for crisp?
Arrange the stalks parallel on a cutting board. Using a sharp knife, cut the stalks into ½- to 1-inch pieces, depending on the recipe.
