What is Regular Butter?
Regular, or block, butter is a simple, traditional product made by churning milk or cream until it separates into butterfat and buttermilk. The resulting fat is what we know as classic butter. It typically contains at least 80% milkfat, with the remaining content being water and milk solids. When kept in the refrigerator, its high fat content and low water content cause it to harden into a firm block. This solid state is why a knife can tear into soft bread or toast if the butter is used straight from the fridge.
What is Spreadable Butter?
Spreadable butter is a blended product designed for convenience. It maintains a soft consistency even when chilled, making it easy to spread directly from the refrigerator without tearing bread. The primary difference lies in its ingredients; spreadable butter combines regular butter with a liquid vegetable oil, such as canola, sunflower, or olive oil. Some versions may also be whipped with air, further lightening the texture. This process lowers the overall milkfat content and increases the percentage of softer, liquid fats, resulting in the desired spreadable texture.
Comparison Table: Regular Butter vs. Spreadable Butter
| Feature | Regular Butter | Spreadable Butter |
|---|---|---|
| Ingredients | Churned cream and salt (optional). | Regular butter blended with vegetable oils (canola, sunflower, etc.). |
| Texture (chilled) | Hard and firm. Requires softening for easy spreading. | Soft and pliable. Spreads easily straight from the fridge. |
| Flavor | Rich, unadulterated dairy flavor. | Mildly altered flavor due to added oils, though still buttery. |
| Best For Baking | Ideal for most baking recipes that require solid, high-fat butter, like flaky pastries, cookies, and cakes. | Generally not recommended for delicate baking, especially recipes requiring solid butter. Can cause baked goods to spread and be thin. |
| Best For Spreading | Less convenient for toast or sandwiches straight from the fridge. | Designed specifically for spreading on toast, bread, or muffins. |
| Price | Often more economical per ounce than spreadable varieties. | Typically more expensive due to the blending and processing required. |
| Fat Type | High in saturated fat. | Lower in saturated fat due to added vegetable oils. |
The Role of Each Butter in Cooking
Choosing the right butter depends heavily on the intended use. For baking, the high fat content and specific consistency of regular butter are often non-negotiable. The solid fat creates crucial pockets of air and steam during baking, which is what gives flaky pastries their signature layers or cookies their structure. Using spreadable butter in these recipes can lead to disappointing, greasy results because the added oils change the fat-to-liquid ratio, causing dough to spread excessively.
However, for simple spreading applications and some cooking methods, spreadable butter offers great convenience. It's perfect for quick toast in the morning or for pan-frying chicken or vegetables where a soft, melting butter is desired. Its lower saturated fat content can also be a consideration for those monitoring their intake, though it's important to note that it's not a diet product and contains similar calories to regular butter.
Making a Homemade Spreadable Butter
If you prefer the taste of pure butter but crave the convenience of a softer product, you can create your own spreadable butter at home with just a few ingredients:
- Start with softened butter: Begin with good-quality, room-temperature unsalted butter.
- Add a neutral oil: Slowly incorporate a neutral vegetable oil like canola, sunflower, or a mild olive oil while mixing. A good starting ratio is 2 parts butter to 1 part oil.
- Whip until fluffy: Use a stand mixer or hand mixer to whip the butter and oil together until the mixture is light and fluffy.
- Add salt and store: Mix in salt to taste, transfer to an airtight container, and chill. You can store extra in the freezer.
Conclusion
In the battle of spreadable versus regular butter, there is no single winner. The best choice is entirely dependent on your needs. For baking projects that rely on the classic properties of butter, reach for the solid block. For everyday convenience when spreading on bread, the softer, blended product is ideal. Understanding the differences in ingredients and texture empowers you to make the right choice for your kitchen, ensuring the best results whether you're baking a cake or simply enjoying a piece of toast.
