Rhubarb, often misunderstood as a fruit but technically a vegetable, is a versatile and nutritious ingredient that can add a unique twist to a variety of dishes, from desserts to savory meals. Its tart flavor and crunchy texture make it a favorite among chefs and home cooks alike. However, to fully appreciate rhubarb’s culinary potential, it’s essential to understand how to pick and prepare it properly. In this article, we will delve into the world of rhubarb, exploring its characteristics, the best methods for picking, and the various ways to prepare it for consumption.
Understanding Rhubarb
Before diving into the specifics of picking and preparing rhubarb, it’s crucial to have a basic understanding of this vegetable. Rhubarb belongs to the Polygonaceae family and is closely related to buckwheat. It is characterized by its large, leafy greens and long, fleshy stalks, which are the edible parts of the plant. Rhubarb is known for its tart flavor, which is due to its high concentration of malic acid and oxalic acid. This acidity not only gives rhubarb its distinctive taste but also contributes to its potential health benefits and culinary versatility.
Health Benefits of Rhubarb
Rhubarb is not just a flavorful addition to meals; it also boasts a range of health benefits. It is rich in vitamins C and K, as well as minerals like potassium and magnesium. Rhubarb also contains a significant amount of dietary fiber, which can help promote digestive health. Furthermore, its antioxidant properties can contribute to protecting against oxidative stress and inflammation in the body. However, it’s worth noting that the leaves of the rhubarb plant are toxic due to their high concentrations of oxalic acid and should never be consumed.
Culinary Uses of Rhubarb
The culinary applications of rhubarb are diverse and exciting. It is perhaps most famously used in pies and tarts, paired with sweet ingredients like strawberries or sugar to balance out its tartness. Rhubarb can also be used in jams, preserves, and sauces, as well as in savory dishes like stews and braises. Its unique flavor profile makes it a great addition to salads and can even be used as a vegetable in dishes like stir-fries. When cooking with rhubarb, it’s essential to remember that its flavor will mellow with heat, so it’s often added towards the end of the cooking process.
Picking Rhubarb
Picking rhubarb at the right time and in the right manner is crucial for ensuring its quality and flavor. Rhubarb is typically ready to harvest in early spring, about 6-8 weeks after the first signs of growth appear. The stalks should be firm, crunchy, and a vibrant red or green color, depending on the variety. Avoid picking stalks that are wilted, soft, or showing signs of flowering, as these can be bitter and less palatable.
When to Pick Rhubarb
The timing of rhubarb harvesting is critical. Early spring is the best time to pick rhubarb, as the stalks are at their most tender and flavorful. Waiting too long can result in stalks that are tough and less palatable. For those growing their own rhubarb, it’s recommended to wait until the plants are at least a year old before harvesting, to ensure the roots have enough time to establish themselves. After the initial harvest, it’s advisable to stop picking the stalks about mid-summer to allow the plant to replenish its energy reserves for the next year’s growth.
How to Pick Rhubarb
Picking rhubarb requires a gentle touch to avoid damaging the plant or the stalks. Here are the steps to follow:
- Hold the stalk near the base and gently twist it away from the plant. This method helps to avoid pulling on the roots and potentially damaging the rhubarb crown.
- Only pick stalks that are at least 10-12 inches long and about the thickness of your thumb. These are typically the most tender and flavorful.
- Avoid pulling on the leaves, as this can cause damage to the plant. Instead, focus on the stalks themselves.
Preparing Rhubarb
Once you’ve picked your rhubarb, the next step is preparing it for use in your favorite recipes. Preparation involves cleaning, trimming, and sometimes cooking the rhubarb to bring out its unique flavor and texture.
Cleaning and Trimming Rhubarb
After picking, rinse the rhubarb stalks under cold running water to remove any dirt or debris. Use a vegetable brush to gently scrub the stalks, especially in the crevices where dirt might accumulate. Remove any leaves, as they are toxic, and trim the ends of the stalks. Cutting off the ends helps to remove any tough or fibrous parts and prepares the rhubarb for cooking.
Cooking Rhubarb
Rhubarb can be cooked in a variety of ways, depending on the desired texture and flavor. It can be stewed, roasted, sautéed, or even pickled. When cooking rhubarb, it’s essential to balance its tartness with sweet or savory ingredients. Sugar, honey, and fruits like strawberries are common pairings for rhubarb in desserts, while in savory dishes, ingredients like onions, garlic, and herbs can complement its flavor.
Rhubarb Cooking Tips
- Stewing Rhubarb: Cut the rhubarb into smaller pieces and stew it with a little water and sugar until it’s tender. This method is great for making jams, sauces, or as a topping for yogurt or oatmeal.
- Roasting Rhubarb: Toss rhubarb pieces with olive oil, salt, and your choice of sweet or savory seasonings, and roast in the oven until caramelized. Roasted rhubarb makes a delicious side dish or can be used as a topping for salads or meats.
- Sautéing Rhubarb: Quickly sauté chopped rhubarb with butter or oil and a pinch of salt. This method preserves the crunch of the rhubarb and can be used in savory dishes or as a side vegetable.
In conclusion, picking and preparing rhubarb is an art that requires attention to detail and a basic understanding of this unique vegetable. By following the guidelines outlined in this article, you can unlock the culinary potential of rhubarb and enjoy its tart flavor and numerous health benefits throughout the year. Whether you’re a seasoned chef or a curious home cook, rhubarb is certainly worth exploring, and with the right techniques, it can become a staple in your kitchen repertoire.
What is rhubarb and how does it grow?
Rhubarb is a type of vegetable that is often used in sweet dishes, particularly pies and tarts. It is a perennial plant that grows from a crown, which is a thick, underground stem that produces new growth every year. Rhubarb plants have large, green leaves that are toxic and should not be eaten, but the stalks are edible and have a tart, sour taste. The plant prefers well-drained soil and full sun to partial shade, making it a great addition to many gardens.

Avoid stalks that are limp, wilted, or have visible signs of decay. Fresh rhubarb should have a slightly sweet, earthy aroma and a crunchy texture.
In addition to selecting the right stalks, it’s also important to consider the season and source of the rhubarb. locally grown, in-season rhubarb is often preferred for its superior flavor and texture.
