Core Ingredients of Classic Lady Finger Biscuits
The composition of a traditional lady finger biscuit, also known as savoiardi, is surprisingly simple, relying on eggs for its distinctive texture. The core ingredients are:
- Eggs: Provide the biscuit's spongy structure. Whipped egg whites create a meringue folded into a batter of egg yolks and sugar, with incorporated air acting as the primary leavening agent.
- Sugar: Granulated sugar is used with eggs for a stable foam, while powdered sugar is dusted on top before baking for a soft crust and sweet exterior.
- Flour: All-purpose flour is gently folded in. Sifting is important for a light, spongy result.
Homemade vs. Store-Bought Ingredients
While classic recipes are simple, commercial lady fingers often include extra ingredients for stability, flavor, and shelf-life. Homemade versions offer freshness and ingredient control.
Homemade Lady Finger Ingredients
Homemade recipes typically include separated eggs, granulated and powdered sugar, sifted all-purpose flour, and sometimes cornstarch for structure, along with vanilla extract and salt for flavor.
Store-Bought Lady Finger Ingredients
Commercial lady fingers start with wheat flour, sugar, and eggs. They often add chemical leavening agents for consistent rise, glucose syrup for moisture, natural flavorings, and stabilizers like sorbitol syrup or guar gum, especially in gluten-free varieties.
Ingredient Alternatives and Variations
Variations cater to dietary needs, aiming to replicate the light, spongy texture with alternative ingredients.
Vegan Lady Finger Biscuits
Vegan lady fingers use aquafaba (chickpea liquid) as an egg substitute, whipped into a meringue-like foam with cream of tartar. Other ingredients include vegan butter or oil, baking powder, flour, and sugar.
Gluten-Free Lady Finger Biscuits
Gluten-free versions use blends of flours like rice, maize, and potato, often with xanthan gum for binding. They still typically use eggs and sugar as a base.
Comparison of Lady Finger Biscuits to Other Desserts
Lady fingers are distinct in their low density and absorbent nature, making them ideal for soaking in desserts, unlike denser cookies or baked goods.

Nutritional Considerations
Lady fingers are primarily a source of carbohydrates from sugar and flour, offering quick energy but lacking significant nutrients. Their low fat content makes them a good base for desserts with more nutritious elements like fruit. For those monitoring sugar intake, homemade versions allow for reduction. Swapping some flour for a higher-fiber option can enhance nutritional value, though it may alter the texture. Store-bought options should be checked for added preservatives and flavorings that might increase sugar and sodium.
Conclusion
Understanding what are lady finger biscuits made out of reveals a simple, traditional recipe centered on eggs, sugar, and flour, resulting in a uniquely light and airy sponge. This texture allows them to absorb liquids without becoming soggy, making them indispensable in desserts like tiramisu. While homemade offers delicate freshness, commercial options provide convenience with added ingredients for consistency. Lady fingers remain a popular and versatile biscuit in baking.
