Why Frisée Has a Bitter Flavor
Yes, frisée is bitter, and this is normal for this leafy green. The bitterness comes from the chicory family, which includes other vegetables like endive and radicchio. The chemical compounds that cause this sharp flavor are sesquiterpene lactones. These compounds also have potential medicinal properties. The intensity of bitterness varies based on the plant part, age, and cultivation. The pale, inner leaves are typically milder than the darker, greener outer leaves.
Factors That Influence Frisée's Bitterness
Several things influence the bitterness in frisée:
- Cultivation Technique: Farmers often use blanching, where the plant is covered to block sunlight. This process restricts the chlorophyll production in the inner leaves, resulting in a paler color and a milder flavor. The resulting yellow heart is the most prized part of the plant for salads.
- Age and Freshness: Younger frisée is less bitter than older plants. Wilting or discoloration on older frisée can indicate more bitterness.
- Seasonality: Frisée is often at its peak from late winter through early spring. This is when it is most likely to be tender and at its ideal flavor balance.
How to Balance the Bitter Flavor
For those who find the bitter taste too strong, it can be easily balanced and complemented with other flavors. Pair frisée with ingredients that provide sweetness, richness, or acidity.
Pairings That Complement Frisée
- Sweet and Fruity: Adding sweet elements can offset the sharpness. Fruits like sliced pears, apples, or dried fruits can help. A drizzle of honey or a sweet, fruity dressing also works well.
- Rich and Savory: The bitter taste provides a perfect counterpoint to rich, savory ingredients. The classic French preparation, salade Lyonnaise, includes warm, salty bacon (lardons), a poached egg, and a vinaigrette. Other additions like goat cheese, walnuts, or cured meats also work well.
- Acidic: Acidity helps to brighten the overall flavor. A vinaigrette with plenty of vinegar or citrus juice, such as a honey-mustard or port vinaigrette, is a classic choice.
- Fat: Creamy dressings or ingredients like avocado can soften the bitter impact.
The Culinary Appeal of Frisée's Bitterness
Frisée's bitterness is its main attraction in the culinary world. It serves as a flavor palate cleanser and a base for more complex dishes. The contrast prevents a dish from tasting one-dimensional and makes other flavors, like the sweetness of a fruit or the richness of bacon, more pronounced. Frisée's crisp, crunchy texture also holds up well against warm dressings and other hearty ingredients. The pepperiness and crispness make it a standout ingredient in mesclun mixes.
