The Sneaky Truth: Uncovering Hidden Cornstarch in Soups & Desserts
Imagine ordering mushroom bisque or crème brûlée at a restaurant, only to later discover they contained an ingredient that conflicts with your dietary needs. For many diners avoiding corn derivatives, this hidden culprit is cornstarch – a common thickener lurking in countless restaurant soups and desserts. Understanding its prevalence is the first step to safer dining.
Why Cornstarch is Everywhere in Restaurant Kitchens
Cornstarch is a chef’s secret weapon: a economical, flavorless powder that:
- Creates silky textures in sauces, gravies, and creamy soups
- Stabilizes custards and pudding-style desserts
- Gives baked goods a lighter crumb But while versatile, it poses real challenges:
Dietary Red Flags:
- Corn Allergies: Triggers reactions in those with corn sensitivities
- Gluten-Free Diets: Risk of cross-contamination during processing
- Keto/Low-Carb: High carb content (7g+ per tbsp) disrupts macros
- Anti-Additive Preferences: Processed ingredient used in place of whole foods
Why You'll Rarely Spot It On Menus
Menus emphasize flavors and presentation, not thickening agents. Even when asked:
- Servers may not know kitchen prep details
- "House-made" claims don’t reveal specific ingredients
- Terms like "velvety" or "silky" often hint at thickeners like cornstarch
