Corn Starch Vs Gelatin: The Ultimate Face-Off
What To Know
- Corn starch produces a smooth and glossy gel, while gelatin produces a firm and elastic gel.
- If gelatin is not soaked in cold water for long enough before dissolving in hot water, it may not form a strong gel.
- Corn starch is a versatile thickener that produces a smooth and glossy gel, while gelatin creates a firm and elastic gel.
When it comes to thickening sauces, soups, and desserts, corn starch and gelatin are two of the most commonly used ingredients. While both are effective thickeners, they have distinct properties and applications. This guide will delve into the differences between corn starch and gelatin, helping you make informed choices when thickening your culinary creations.
Properties of Corn Starch
- Source: Derived from corn kernels
- Appearance: Fine white powder
- Solubility: Soluble in cold water
- Thickening mechanism: Forms a gel through a process called gelatinization
- Texture: Produces a smooth, glossy, and slightly opaque gel
- Flavor: Neutral
- Heat stability: Stable at high temperatures
Properties of Gelatin
- Source: Derived from animal collagen (typically from pig or cow skin)
- Appearance: Colorless or slightly yellow powder
- Solubility: Insoluble in cold water; requires soaking in cold water before dissolving in hot water
- Thickening mechanism: Forms a gel through a process called thermogelation
- Texture: Produces a firm, elastic, and translucent gel
- Flavor: Slightly meaty or savory
- Heat stability: Can withstand high temperatures, but may melt or weaken if overheated
Applications of Corn Starch
- Sauces: Thickening sauces for stir-fries, gravies, and sauces
- Soups: Adding body and thickness to soups and stews
- Puddings: Creating smooth and creamy puddings
- Baked goods: Enhancing texture and moisture in cakes, cookies, and muffins
- Pie fillings: Thickening fruit fillings for pies and tarts
Applications of Gelatin
- Jellies: Creating firm and glossy jellies
- Mousses: Providing structure and stability to light and airy mousses
- Panna cotta: Thickening this Italian dessert into a creamy, pudding-like consistency
- Marshmallows: Giving marshmallows their soft and chewy texture
- Gummy candies: Creating the chewy texture of gummy bears and other candies
Comparison of Corn Starch and Gelatin
| Feature | Corn Starch | Gelatin |
| — | — | — |
| Source | Corn kernels | Animal collagen |

Choosing the Right Thickener
When selecting between corn starch and gelatin, consider the following factors:
- Desired texture: Corn starch produces a smooth and glossy gel, while gelatin produces a firm and elastic gel.
- Heat stability: Corn starch is more heat stable than gelatin, making it suitable for recipes that require prolonged cooking.
- Flavor: Corn starch has a neutral flavor, while gelatin has a slightly meaty or savory flavor that may not be suitable for all applications.
- Dietary restrictions: Gelatin is not suitable for vegetarians or vegans, while corn starch is a plant-based option.
Troubleshooting Corn Starch and Gelatin
- Lumpy corn starch: If corn starch is not dissolved properly in cold water before adding to hot liquids, it can form lumps. To prevent this, whisk the corn starch with cold water until a slurry forms before adding to the hot liquid.
- Weak gelatin: If gelatin is not soaked in cold water for long enough before dissolving in hot water, it may not form a strong gel. Ensure you follow the instructions carefully and soak the gelatin for the recommended time.
- Melting gelatin: Gelatin can melt or weaken if overheated. Avoid boiling gelatin or heating it to extremely high temperatures.
Key Points: The Verdict
Corn starch and gelatin are both effective thickeners, but they have different properties and applications. Corn starch is a versatile thickener that produces a smooth and glossy gel, while gelatin creates a firm and elastic gel. By understanding the differences and comparing them with the desired outcome, you can choose the right thickener for your culinary creations.
Basics You Wanted To Know
