Rhubarb, with its vibrant pink or reddish stalks, often gets a curious glance in the produce aisle. Its resemblance to celery, in terms of appearance, leads many to wonder: does rhubarb taste like celery? The short answer is a resounding no. However, the long answer is far more interesting, delving into the nuances of flavor, texture, and culinary applications that set these two vegetables apart.
Decoding the Flavors: Rhubarb’s Tartness vs. Celery’s Freshness
Rhubarb and celery, while visually similar in their stalk-like structure, offer drastically different taste experiences. Understanding these differences is key to appreciating their individual roles in the kitchen.
Rhubarb’s Signature Tartness
Rhubarb is known for its intense tartness, almost to the point of being sour. This is due to the presence of malic acid, a compound also found in apples. This tartness is the defining characteristic of rhubarb and what makes it such a unique culinary ingredient. Raw rhubarb is generally considered unpalatable due to its overwhelming sourness.
Celery’s Mild and Refreshing Taste
In stark contrast, celery boasts a mild, slightly salty, and refreshing flavor. It has a crisp, watery texture and a subtle sweetness that makes it a popular snack and ingredient in various dishes. The taste of celery is quite different from rhubarb. It is often used as a background flavor, adding a fresh, herbaceous note to soups, salads, and other preparations.
Texture and Culinary Uses: Where the Paths Diverge
Beyond the flavor profile, rhubarb and celery also differ significantly in their texture and how they are used in cooking.
Rhubarb’s Transformation Through Cooking
Rhubarb’s texture is firm and fibrous when raw. However, when cooked, it breaks down into a soft, almost jam-like consistency. This characteristic makes it ideal for pies, crumbles, jams, sauces, and compotes. The tartness of rhubarb is typically balanced with sugar during cooking, creating a delightful sweet-tart flavor combination. The cooking process allows rhubarb to shine.
Celery’s Versatility in Raw and Cooked Forms
Celery retains its crispness even when cooked, although it can become slightly softer. It’s commonly eaten raw as a healthy snack, often paired with dips like hummus or peanut butter. In cooked dishes, celery adds texture and flavor to soups, stews, stir-fries, and stuffings. Its versatility makes it a staple in many cuisines. Celery is a versatile ingredient.
Botanical Background: Understanding the Plant Families
Rhubarb and celery belong to different plant families, which further explains their distinct characteristics.
Rhubarb’s Relation to Buckwheat
Rhubarb (Rheum rhabarbarum) belongs to the Polygonaceae family, which also includes buckwheat and sorrel. This family is known for plants with a slightly acidic or tangy flavor profile.
Celery’s Membership in the Carrot Family
Celery (Apium graveolens) belongs to the Apiaceae family, also known as the carrot family. This family includes other aromatic vegetables like carrots, parsley, and dill.
Nutritional Value: A Comparison of Rhubarb and Celery
Both rhubarb and celery offer valuable nutrients, but their nutritional profiles differ.
Rhubarb’s Vitamins and Minerals
Rhubarb is a good source of vitamin K, vitamin C, and fiber. It also contains calcium, although its bioavailability may be limited due to the presence of oxalic acid. Oxalic acid can bind to calcium and inhibit its absorption. However, cooked rhubarb has a lower concentration of oxalic acid, making it easier for the body to absorb nutrients.
Celery’s Hydration and Fiber Benefits
Celery is primarily composed of water, making it a hydrating vegetable. It also provides fiber, vitamin K, and some vitamin C. Celery contains antioxidants and compounds that may have anti-inflammatory properties.
Culinary Applications: Rhubarb’s Sweet Side vs. Celery’s Savory Role
Rhubarb and celery are used in very different ways in the culinary world.
Rhubarb in Desserts and Preserves
Rhubarb is most commonly used in sweet applications, such as pies, crumbles, jams, and sauces. Its tartness pairs well with sweet fruits like strawberries and apples. Rhubarb is also used to make rhubarb wine and rhubarb liqueur. The sweetness balances the tartness.
Celery in Soups, Salads, and Snacks
Celery is primarily used in savory dishes, adding flavor and texture to soups, stews, salads, and stuffings. It’s also a popular ingredient in vegetable juices and is often served as a healthy snack with dips. It is a versatile ingredient in different cuisines.
Why the Confusion? Appearance and Misconceptions
The confusion between rhubarb and celery likely stems from their visual similarity. Both have long, stalk-like structures that can be mistaken for one another at first glance.
The Stalk Similarity

FAQ 1: Does rhubarb actually taste like celery?
The short answer is no, rhubarb does not taste like celery, despite their visual similarities. Raw rhubarb stalks are intensely tart, almost sour, due to their high concentration of malic acid. This tartness is the dominant flavor profile and bears little resemblance to the mild, slightly salty, and refreshing taste of celery.
Celery, on the other hand, is known for its subtle, watery flavor and crisp texture. It lacks the pronounced acidity that characterizes rhubarb. While both vegetables may share a certain crispness when raw, their taste profiles are vastly different. Rhubarb requires cooking and often sweetening to be palatable, whereas celery is commonly eaten raw as a snack or in salads.
FAQ 2: Why do people sometimes compare rhubarb to celery?
The comparison between rhubarb and celery often stems from their similar appearance. Both vegetables feature long, fibrous stalks and share a pale green or reddish hue, especially at the base. This visual resemblance can lead to initial assumptions about their flavor profiles, even though they are botanically unrelated.
Furthermore, both vegetables are frequently used in savory dishes, albeit in very different ways. Celery is a common ingredient in soups, stews, and stuffing, providing a subtle background flavor. While rhubarb is most often sweetened for pies and desserts, it can also be used in savory chutneys and sauces, perhaps further blurring the lines for some regarding their culinary uses.
FAQ 3: How should rhubarb be prepared to reduce its tartness?
The key to taming rhubarb’s intense tartness lies in cooking it, usually with the addition of sugar or other sweeteners. This process helps to break down the acids in the rhubarb, creating a more palatable and balanced flavor. Simple stewing with sugar is a common method, allowing the rhubarb to soften and release its juices.
Beyond sugar, other ingredients can complement and offset the tartness. Pairing rhubarb with fruits like strawberries or raspberries can naturally sweeten the dish and enhance its flavor complexity. Spices such as ginger, cinnamon, or cloves can also add warmth and depth, creating a more harmonious taste experience.
FAQ 4: Is rhubarb safe to eat raw like celery?
No, rhubarb should not be eaten raw in large quantities due to the presence of oxalic acid, which is toxic. While small amounts of raw rhubarb might not cause significant harm to most people, the levels of oxalic acid can lead to symptoms such as nausea, vomiting, and abdominal pain. In very high doses, it can even be fatal.
Cooking rhubarb significantly reduces the oxalic acid content, making it safe to consume. The leaves of the rhubarb plant are particularly high in oxalic acid and should never be eaten under any circumstances. Always discard the leaves and only use the stalks for culinary purposes.
FAQ 5: What are some popular dishes that feature rhubarb?
Rhubarb is most famously known for its use in sweet desserts, particularly pies and crumbles. Rhubarb pie, often combined with strawberries, is a classic spring dessert. Rhubarb crumble, topped with a buttery oat streusel, offers a comforting and textural contrast to the tart fruit.
Beyond desserts, rhubarb can also be used in savory applications. Rhubarb chutney, with its sweet and sour flavor, makes a delicious accompaniment to grilled meats or cheeses. Rhubarb sauce can be a vibrant and tangy addition to roasted pork or duck. Its versatility extends to jams, preserves, and even cocktails.
FAQ 6: Can rhubarb be used as a celery substitute in recipes?
While the visual similarity might tempt you, rhubarb is not a suitable substitute for celery in most recipes. The intense tartness of rhubarb would significantly alter the flavor profile of dishes designed for the subtle taste of celery. The distinct textures also contribute to their incompatibility as substitutes.
Celery provides a mild, slightly salty flavor and a crisp texture that acts as a supporting ingredient in many savory dishes. Using rhubarb in place of celery would overpower the other flavors and create an unbalanced result. While experimentation in the kitchen is encouraged, these two vegetables are simply too different to be swapped effectively.
FAQ 7: What are the nutritional benefits of rhubarb?
Rhubarb, when consumed in moderation, offers some nutritional benefits. It is a good source of dietary fiber, which aids digestion and promotes gut health. It also contains vitamin K, important for blood clotting and bone health, as well as vitamin C, an antioxidant that supports the immune system.
However, it’s important to remember that rhubarb is often consumed with added sugar, which can offset some of its nutritional benefits. It also contains oxalic acid, which, while reduced through cooking, can still bind to minerals like calcium and prevent their absorption. Therefore, it’s best to enjoy rhubarb as part of a balanced diet and in moderation.
