Crushed Red Pepper

Typically an American product, crushed red pepper consists of a medley of dried red chili peppers. Often, these blends might contain a mix of different peppers, including but not limited to cayenne, ancho, and bell peppers. The presence of seeds boosts the heat quotient. It gained prominence as a staple in Italian-American pizzerias, sprinkled over pizzas and pastas, giving them a spicy kick.

Chili Flakes

Chili flakes, on the other hand, are generally more specific in their makeup, originating from a singular type of chili. For instance, Korean chili flakes, or “gochugaru,” come from sun-dried red chili peppers, while Turkish chili flakes, known as “pul biber,” have a distinctive flavor and color. The specificity of the chili used gives chili flakes a more defined and consistent flavor profile compared to the mixed nature of crushed red pepper.

Physical Appearance

The beauty of spices lies not just in their flavors, but also in their aesthetics. Both crushed red pepper and chili flakes are visually appealing, with vibrant colors and textures that can entice any culinary enthusiast. However, when looked at closely, there are discernible differences between the two.

Crushed Red Pepper

• Texture: As the name suggests, crushed red pepper has a coarser texture. It’s not uniformly crushed, which means you can often see larger chunks of pepper and seeds interspersed with finer particles.
• Size: The pieces in crushed red pepper can vary, but they are generally larger than standard chili flakes. The inconsistency in size is a notable characteristic.
• Color: The color palette of crushed red pepper can be diverse because of the mix of peppers used. It ranges from bright red to deep burgundy, often with visible pale yellow seeds.

Chili Flakes

• Texture: Chili flakes usually have a more consistent texture, as they are derived from a single type of chili. They’re finely crushed, offering a more uniform appearance.
• Size: The particles in chili flakes are relatively consistent in size, typically smaller than those in crushed red pepper. This uniformity gives them a slightly powdery appearance.
• Color: The color of chili flakes can vary depending on the specific chili used. For instance, gochugaru (Korean chili flakes) might have a vibrant reddish-orange hue, while Turkish pul biber can range from deep red to a slightly purplish shade.

Ingredients and Composition

Both crushed red pepper and chili flakes derive from chili peppers, but their makeup can vary, resulting in different flavor profiles, spiciness levels, and culinary applications. Understanding the ingredients and composition of each is crucial to distinguishing them and using them effectively in dishes.

Crushed Red Pepper

• Constituents: Crushed red pepper is a blend, often comprising several types of dried red chili peppers. Some common peppers found in these mixes include cayenne, ancho, bell, and others. The specific mix can vary based on the brand or regional preferences.
• Seeds: A defining characteristic of crushed red pepper is the inclusion of seeds. These seeds are not just filler; they play a significant role in the overall heat and flavor of the blend.
• Flavor Profile: Because it’s a blend, crushed red pepper can have a multifaceted flavor. Depending on its constituents, it might offer smokiness, sweetness, and of course, heat.

Chili Flakes

• Constituents: Chili flakes are generally more specific, derived from a single type of chili. This specificity provides them with a consistent and defined flavor. Examples include the aforementioned gochugaru from Korea and pul biber from Turkey, but numerous other regional varieties exist.
• Seeds: Some chili flakes include seeds, while others might be devoid of them. The inclusion largely depends on the type of chili and the intended flavor and heat profile.
• Flavor Profile: As they’re made from a specific type of chili, chili flakes tend to have a more predictable and consistent flavor. This can range from smoky to sweet to extremely spicy, based on the chili of origin.

Impact of Seeds on Spiciness

The capsaicin content in chili peppers, responsible for the spicy sensation, is primarily concentrated in the pith or the inner white membranes of the pepper, and to a lesser extent, in the seeds. While the seeds themselves aren’t the spiciest part of a chili, they absorb and retain capsaicin from the pith, making them relatively spicy.

In crushed red pepper, the inclusion of seeds amplifies the overall heat level. On the other hand, with chili flakes, the presence or absence of seeds can affect their spiciness, but the primary factor is the type of chili used.

Flavor Profile and Heat Level

The world of chilies is vast and vibrant, with each variant bringing its distinct taste and spiciness to the table. When it comes to crushed red pepper and chili flakes, these differences become even more nuanced, offering a diverse palette of flavors and heat levels.

Crushed Red Pepper

• Flavor: Being a blend of various peppers, crushed red pepper offers a complex flavor profile. Depending on its mix, you might detect hints of sweetness, smokiness, and even fruity undertones.
• Heat: Generally, crushed red pepper provides a moderate and lingering heat, which can vary based on the specific peppers included in the blend.

Chili Flakes

• Flavor: Chili flakes, sourced from a singular type of chili, offer a more consistent flavor. The taste can range from smoky (like chipotle flakes) to slightly sweet and fruity (like Aleppo pepper flakes) to intensely spicy.
• Heat: The heat level of chili flakes is largely dictated by the chili of origin. For example, flakes derived from milder chilies will be less spicy compared to those from hotter varieties.

The Heat Index: Scoville Heat Units (SHU)

The spiciness of chilies and chili-derived products is measured using the Scoville Heat Scale. Developed by Wilbur Scoville in 1912, this scale measures the concentration of capsaicin, the chemical responsible for the spicy sensation. The unit of measurement is the Scoville Heat Unit (SHU). Essentially, SHU indicates the amount of capsaicin present.

Comparison of Typical Scoville Ratings

• Crushed Red Pepper: Given its mixed nature, pinning down an exact SHU for crushed red pepper can be challenging. However, on average, most crushed red pepper you find at stores might range from 30,000 to 50,000 SHU. This is a general estimate, as the heat can vary significantly based on the blend.
• Chili Flakes: The SHU for chili flakes is predominantly dependent on the chili used. For reference:
  • Gochugaru (Korean Chili Flakes): Typically ranges between 4,000 to 8,000 SHU, giving a moderate heat.
  • Pul Biber (Turkish Aleppo Pepper Flakes): Ranges from 10,000 to 15,000 SHU, offering a mild to moderate heat.
  • Chipotle Flakes: Can range from 5,000 to 10,000 SHU, characterized by a smoky flavor and mild heat.

It’s worth noting that individual sensitivity to capsaicin varies, so what might be mildly spicy for one person could be very spicy for another.
