WHAT IS RHUBARB?

Before I can convince you to make this delectable cake, I should probably explain what is in it!

Rhubarb, with its vibrant reddish or greenish stalks, is a distinct spring vegetable and one of the few that are still truly seasonal. While rhubarb may resemble celery, it stands out with its beautiful pink/magenta stalks, making it highly appetizing. It’s important to note that only the stalks are edible, as the leaves contain high levels of oxalic acid and can be toxic if consumed in large quantities. Therefore, it’s crucial to avoid using the leaves for any purpose.

Rhubarb has a tart and tangy flavor, which is why it is often combined with sweeter fruits like apples or strawberries to balance out its acidity. Rhubarb is generally in season between April and June, so now is the perfect time to stock up, try out some recipes, or even freeze some for later use.

STORING RHUBARB CAKE

Before storing the rhubarb cake, make sure it has cooled down to room temperature. Store any leftover cake in an airtight container in the refrigerator to keep it fresh. The cool temperature will help preserve the cake and prevent it from spoiling. Rhubarb cake, like most cakes, is best enjoyed fresh. Try to consume the leftovers within 2-3 days for optimal taste and texture. Beyond that timeframe, the cake may start to dry out or lose its flavor.

FAQ

Is it better to eat rhubarb raw or cooked?

Raw rhubarb tends to have a sour taste and a tough texture, making it challenging to chew. However, if the stalks are young and tender, it is possible to eat them raw in small quantities. Most commonly, rhubarb is prepared by cooking it, and it is generally recommended to cook it with an generous amount of sugar. Adding sugar helps to counterbalance the tartness, enhancing its overall flavor and making it more enjoyable to eat.

How to store rhubarb?

Store trimmed stalks of rhubarb in a loose plastic bag or wrap it loosely in a damp paper towel. Put it in the vegetable crisper drawer of your refrigerator. The perforations or the damp towel will help to maintain the right level of moisture without causing the stalks to become soggy.
