Crisco. The name is synonymous with baking for generations of home cooks. From flawlessly flaky pie crusts to moist, tender cakes, Crisco has held a prominent place in kitchens worldwide. But what exactly is this ubiquitous shortening made of? The answer, while seemingly simple, involves a fascinating history of innovation and the science of fat modification.
The Origins and Evolution of Crisco
To understand Crisco’s composition, it’s essential to delve into its origins. Before Crisco’s debut, lard and butter were the primary fats used in baking. These, however, had drawbacks. Lard could be inconsistent in quality, and butter was expensive and prone to spoilage. In the late 19th century, chemists began exploring ways to solidify liquid vegetable oils, aiming to create a more stable and affordable alternative.
William Procter and James Gamble, the founders of Procter & Gamble (P&G), entered the picture through an unusual route – candle making. They sourced cottonseed oil, a byproduct of the booming cotton industry. Recognizing the potential of this oil, they partnered with chemist Edwin Kayser to develop a process called hydrogenation.
Hydrogenation involves adding hydrogen atoms to the unsaturated fatty acids in vegetable oils. This process saturates the fatty acids, raising the oil’s melting point and transforming it from a liquid into a solid or semi-solid state at room temperature. In 1911, Crisco, short for “crystallized cottonseed oil,” was born.
The Primary Ingredient: Vegetable Oil
The foundation of Crisco is, as the name originally suggested, vegetable oil. While cottonseed oil was the original base, the composition has evolved significantly over time. Today, Crisco is primarily made from a blend of soybean oil, palm oil, and fully hydrogenated cottonseed oil. The specific ratio of these oils can vary, but the goal remains the same: to create a stable, semi-solid fat with desirable baking properties.
Soybean Oil: A Versatile Component
Soybean oil is a widely used vegetable oil known for its neutral flavor and affordability. It’s extracted from soybeans and undergoes refining to remove impurities and improve its stability. In Crisco, soybean oil contributes to the product’s overall texture and consistency.
Palm Oil: Stability and Texture Enhancer
Palm oil, derived from the fruit of the oil palm tree, is a semi-solid fat at room temperature due to its higher saturated fat content. It adds stability to Crisco, helping it maintain its shape and prevent it from becoming too soft or oily.
Fully Hydrogenated Cottonseed Oil: Achieving the Right Consistency
While cottonseed oil is no longer the sole ingredient, fully hydrogenated cottonseed oil still plays a crucial role in Crisco’s formulation. Full hydrogenation ensures that all the unsaturated fatty acids in the cottonseed oil are saturated with hydrogen, resulting in a hard, waxy fat. This component contributes to Crisco’s solid consistency and its ability to create flaky pastries.
The Hydrogenation Process: The Key to Crisco’s Texture
Hydrogenation is the cornerstone of Crisco’s unique texture and functionality. As mentioned earlier, this process involves adding hydrogen atoms to the unsaturated fatty acids in vegetable oils. The degree of hydrogenation determines the hardness and melting point of the resulting fat.
Fully hydrogenated oils, like the cottonseed oil used in Crisco, are completely saturated with hydrogen. This makes them solid at room temperature and highly stable, meaning they are less prone to oxidation and rancidity. Partially hydrogenated oils, on the other hand, are only partially saturated, resulting in a softer, more spreadable fat.
It’s important to note that partially hydrogenated oils were once a common ingredient in Crisco and other processed foods. However, they have been largely phased out due to health concerns related to trans fats.
The Trans Fat Issue: A Historical Perspective
Trans fats are a type of unsaturated fat that is formed during the partial hydrogenation process. Studies have linked trans fats to an increased risk of heart disease, leading to regulations and efforts to eliminate them from the food supply.
Modern Crisco formulations do not contain partially hydrogenated oils or trans fats. The hydrogenation process is carefully controlled to ensure full hydrogenation, eliminating the formation of trans fats.
Other Ingredients in Crisco
While vegetable oils are the primary components of Crisco, other ingredients are added to enhance its performance and stability.
Mono- and Diglycerides: Emulsification and Texture
Mono- and diglycerides are emulsifiers, meaning they help to blend oil and water-based ingredients together. In Crisco, they contribute to a smooth, consistent texture and prevent the separation of ingredients. They also improve the incorporation of air into batters, resulting in lighter, more tender baked goods.
TBHQ and Citric Acid: Preservatives
TBHQ (tert-butylhydroquinone) and citric acid are antioxidants that act as preservatives. They prevent the oxidation of fats and oils, extending Crisco’s shelf life and maintaining its quality. Oxidation can lead to rancidity and off-flavors, so these preservatives are essential for preserving the product’s freshness.
Why Use Crisco in Baking? The Benefits
Crisco offers several advantages in baking, making it a popular choice among bakers:
- Shortening Power: Crisco is a “shortening,” meaning it inhibits the formation of gluten in doughs and batters. This results in tender, flaky textures in pastries, cookies, and pie crusts.
- Neutral Flavor: Crisco has a neutral flavor, allowing the other ingredients in a recipe to shine through. It doesn’t impart any unwanted taste to baked goods.
- High Melting Point: Crisco’s high melting point contributes to its ability to create flaky layers in pastries. The solid fat creates pockets of air that expand during baking, resulting in a light, airy texture.
- Stability: Crisco is a stable fat, meaning it doesn’t break down easily at high temperatures. This makes it suitable for deep-frying as well as baking.
- Cost-Effectiveness: Crisco is generally more affordable than butter, making it a budget-friendly option for bakers.
Crisco vs. Butter: A Comparison
While both Crisco and butter are fats used in baking, they have different properties and produce different results.
- Flavor: Butter has a distinct, rich flavor that enhances the taste of baked goods. Crisco, on the other hand, has a neutral flavor.
- Texture: Butter contains water, which can contribute to a slightly tougher texture in some baked goods. Crisco, being pure fat, produces a more tender and flaky texture.
- Melting Point: Butter has a lower melting point than Crisco, which can affect the texture of pastries. Crisco’s higher melting point helps create distinct layers of flaky dough.
- Fat Content: Both Crisco and butter are high in fat, but butter also contains milk solids and water.
- Browning: Butter tends to brown more quickly than Crisco due to the presence of milk solids.
Ultimately, the choice between Crisco and butter depends on the desired flavor and texture of the baked good. Some recipes benefit from the flavor of butter, while others require the tenderness and flakiness that Crisco provides. Some bakers even use a combination of both for the best of both worlds.
The Future of Crisco: Innovations and Alternatives
As consumer preferences evolve and concerns about health and sustainability grow, Crisco continues to adapt. The company is exploring alternative oil sources and formulations to meet the changing needs of bakers.
There’s increasing interest in plant-based and sustainable alternatives to traditional Crisco. These alternatives often utilize blends of vegetable oils, such as shea butter, coconut oil, and sunflower oil, to mimic the texture and performance of Crisco.

What are the primary ingredients in Crisco shortening?
Crisco shortening is primarily made from vegetable oils, specifically soybean oil, cottonseed oil, and fully hydrogenated cottonseed oil. These oils are carefully selected and processed to achieve the desired texture and performance characteristics for baking and cooking. The exact blend of oils can vary slightly depending on the specific Crisco product.
The process of hydrogenation converts liquid vegetable oils into a solid or semi-solid form at room temperature. This is achieved by adding hydrogen atoms to the unsaturated fatty acids in the oil, increasing their saturation and raising their melting point. Fully hydrogenated cottonseed oil contributes significantly to the product’s solid consistency and stability.
Is Crisco shortening considered a trans fat?
Historically, Crisco shortening contained trans fats due to the partial hydrogenation process used in its manufacture. Partial hydrogenation created trans fats as a byproduct. However, in response to health concerns, Crisco reformulated its products.
Modern Crisco shortening products are formulated to be trans fat-free, typically containing less than 0.5 grams of trans fat per serving, which allows them to be labeled as “0g trans fat” according to FDA regulations. This reformulation involved using fully hydrogenated oils and interesterification to achieve the desired texture and performance without generating trans fats.
How is Crisco shortening manufactured?
The manufacturing of Crisco involves several key steps to transform liquid vegetable oils into a solid shortening. First, the raw oils, usually soybean and cottonseed oil, are refined to remove impurities and undesirable flavors or odors. This ensures a clean and neutral-tasting product.
Next, the oils undergo hydrogenation, which saturates the fatty acids and raises the melting point. The oils are then often interesterified, a process that rearranges the fatty acids on the glycerol backbone to create a smoother, more consistent texture. Finally, the shortening is cooled, solidified, and packaged for sale.
What is the purpose of hydrogenation in Crisco shortening?
Hydrogenation is a crucial process in the production of Crisco shortening. It converts liquid vegetable oils into a semi-solid or solid form at room temperature, giving Crisco its characteristic texture and consistency. This is achieved by adding hydrogen atoms to the double bonds in unsaturated fatty acids, making them more saturated.
The hydrogenation process also improves the stability of the oil, making it less prone to oxidation and rancidity. This extends the shelf life of Crisco shortening and ensures it remains usable for a longer period. Fully hydrogenated oils contribute to the smooth texture and consistent performance of the shortening in baking.
What are some common uses for Crisco shortening in cooking and baking?
