Did you ever wonder what to do with a glut of rhubarb? Are you stuck with baking the exact cake over and over again? Here you will learn everything there is to know about cooking, baking, or preserving rhubarb. And just in case you are wondering what kind of cake I bake repeatedly, it’s this simple and comforting Rhubarb Crumb Cake.

What is rhubarb?

A herbaceous perennial plant growing in cooler climates. Its origins are unknown, but what is know is that the plant was primarily grown for medicinal purposes before the 18^th century. Then, during the early 18^th century, people started growing it as a vegetable, mainly in England and Scandinavia.

It can be pink, green streaked with pink, or completely green. When searching for a recipe, you will see pink images of jam or desserts, while those on this blog are primarily green.

The reason for that is that I use the stalks of a standard green (slightly streaked with pink) plant growing in my neighbor’s garden. I would never dream about buying the pink supermarket stalks just for the color when there is so much growing wildly next door.

Vegetable or fruit?

Botanically, rhubarb is a vegetable, meaning it consists of roots, stalks, and leaves (while fruit is supposed to have seeds).

However, legally (in the US), the plant was classified as a fruit in 1947. The reasoning behind it was that people use it mainly to make cakes, desserts, and jams. This way, importers would pay fewer taxes when dealing with rhubarb than they would pay if the plant would have been classified as a vegetable.

Is rhubarb poisonous?

The stalks are edible, but the leaves are poisonous. They contain oxalic acid, which is toxic to both humans and animals. Eating several pounds of leaves (!!!!!) will cause stomach pain, nausea, diarrhea, and vomiting. But who would eat that?

Season

The plant has a short season in spring; try to make the most of it! Depending on where you live, you can pick it between April and the end of June.

How to pick rhubarb?

• Pick firm, upright, glossy stalks. The leaves should also look fresh and not be wilted.
• Grab the stalk near the bottom, twist it gently to the side and pull it up; it will easily separate from the rest of the plant. Discard the leaves.
• The best time to pick it is when the stalks are about 25-30 cm/ 10-12 inches long. But I don’t bother if the stalks are larger than that; if they look crisp and fresh, they will still taste great.
• Although technically, you can harvest it until the fall, it is better to stop at the end of June/ beginning of July to allow the plant to store enough energy to make it through the winter and grow again in spring.

How to prepare it?

• Discard the leaves, they are poisonous!
• Snap off the root ends; they might feel slightly slimy, but that’s ok; you will discard them anyway.
• Wash the stems thoroughly under running water. Dry with kitchen towels.
• Chop the stalks as instructed in the recipe you are following. If they are too wide, you can half them lengthwise before chopping them into smaller pieces.
• Peeling is unnecessary unless the peel is damaged in places or the stalks are very large (older). If the peel is blemished, remove those spots with a small knife.

How to store rhubarb?

You can store the whole stems in the crisp drawer of the refrigerator. Or chop the plant first and store it in airtight containers in the fridge. It will keep for up to 4 days.

How to preserve rhubarb?

Freeze:

• Clean and chop it into small pieces. Place in freezer bags and freeze. It will keep for about one year. For detailed instructions, see How to Freeze Rhubarb.
• Frozen rhubarb can be used in most recipes. Defrost and drain thoroughly before using. If you find you still have lots of frozen pieces in the freezer shortly before the new season, you can even use them to make jam.

Can:

• Canning or Preserving Rhubarb in jars is quick and easy. And incredibly delicious, so good, you can eat it as it is, instead of dessert.
• Or you can use it to top other desserts, for instance, custards or puddings. You can use it to make a trifle, mix it with yogurt or quark, or serve it with a dollop of whipped cream or sweetened crème Fraiche.
• Delicious for filling crepes or for topping pancakes, semolina, or rice pudding.

Jam:

• I make several kinds of rhubarb jam every spring, starting with the most uncomplicated and the most aromatic Rhubarb Butter, which allows you to use a great deal of the plant at a time.
• And there are endless other jam combinations as well. Try this amazing Blueberry Rhubarb Jam, the Strawberry Rhubarb Jam (No Pectin), the Rhubarb Raspberry Jam, the Sugar-Free Jam, or my newest discovery: Rhubarb and Orange Jam. In the recipe card, you will find a bonus recipe for a jam mixed with ginger.

Drinks:

• I make this incredibly aromatic Rhubarb Syrup every spring. Serve with sparkling water and ice cubes. Add to other drinks, like sparkling wine, gin, vodka, and so on.
• You can also try this Rhubarb and Ginger Gin; it’s fantastic!

How to Cook with Rhubarb?

Rhubarb is an incredibly versatile plant when it comes to cooking. You can use it like you would any other fruit and make desserts and cakes. Or you can cook savory rhubarb dishes.

Cooking rhubarb in a savory way:

• Use the stalks to make soups, stews, curries, and so on. You can even add raw pieces to salads.
• Start with this tangy and aromatic Rhubarb Soup with Bacon Omelet; it tastes better than you could imagine. And you should cook the Rhubarb Chicken, our favorite savory rhubarb recipe.
• The plant is also excellent when cooked into curries. How about a Rhubarb Chicken Curry or a Sweet and Sour Rhubarb Fish Curry? They are both packed with flavor.

Rhubarb desserts:

• How about a delicious and straightforward Apple and Rhubarb Crumble? I think I bake that recipe or the Rhubarb Crisp with Apples and Oatmeal every spring. Perfect recipes for using frozen stalks as well.
• And then there is this delicious compote perfect for filling French crepes or for serving over pancakes or other desserts.
• Not to forget Nigella Lawson’s Baked Rhubarb Custard, a typical British recipe, comforting and delectable.
• And try this simple and flavorful dish of Stewed Rhubarb and Apples; it’s amazing, especially when served with vanilla ice cream or custard.

Baking with rhubarb:

• Try The Best Rhubarb Meringue Pie; I am convinced you will not find a better recipe for this kind of pie; it’s just out of this world! Or the Rhubarb Meringue Cake. The same tangy and sweet topping combination, but this time on a soft cake base. You will love it!
• Combine the plant with other berries to make Rhubarb Loaf Cake with Blackberries or Strawberry Rhubarb Bundt Cake. You can combine it with strawberries again to make a delicious Rhubarb Crumble Tart with Strawberries. Or try our favorite Rhubarb Blueberry Tart or the Rhubarb and Ginger Cake.

The rhubarb season is almost to an end, but I will keep adding a couple of recipes now and, for sure, quite a few of them next year as well. So, if you love rhubarb as much as we do, do give some of these recipes a try; you will not be disappointed. And I would love to hear some feedback!
