How to Thicken Lemon Curd Without Corn Flour

Your lemon curd dreams are about to come true!


Gelatin can be used to thicken lemon curd without corn flour by adding it to the mixture. When making your lemon curd, simply sprinkle gelatin over the lemon juice and let it sit for a few minutes until it softens.

Then, gently heat the lemon juice and gelatin mixture until the gelatin dissolves completely. Next, whisk together the eggs and sugar in a separate bowl. Slowly pour the heated lemon juice into the egg mixture, whisking continuously.

Return the mixture to the heat and cook until it thickens, stirring constantly. The gelatin will help to set the lemon curd and give it a smooth, velvety texture. You can then refrigerate it until it is firm and ready to be enjoyed.

Arrowroot Powder

Arrowroot powder is a great alternative for achieving a thicker consistency in lemon curd. It is a gluten-free starch derived from the root of the arrowroot plant. When used as a thickening agent, it creates a smooth and glossy texture, perfect for lemon curd. To use it, simply mix it with water to create a slurry and add it to the lemon curd mixture. As the mixture heats, the arrowroot powder will thicken it without changing the taste or color. This versatile ingredient can be used in sweet and savory recipes, making it a valuable addition to your pantry.

Tapioca Starch

Tapioca starch, derived from the cassava root, is a versatile thickening agent that can be used in various recipes. It’s perfect for thickening lemon curd without corn flour.

To use tapioca starch, start by whisking it with a small amount of liquid from your lemon curd until it forms a smooth slurry. Then, add the slurry to the rest of the lemon curd mixture while continuously stirring.

As the tapioca starch heats up, it will thicken the curd, creating a smooth and creamy texture. Keep in mind that tapioca starch thickens quickly, so be sure to monitor the consistency closely.

Once the desired thickness is reached, remove the curd from the heat and let it cool. Enjoy your delicious, corn-free lemon curd!

Potato Starch

Potato starch, derived from potatoes, is a commonly used thickening agent in many recipes. If you’re looking for an alternative to corn flour to thicken your lemon curd, potato starch is a great option.

It has a neutral flavor and works well in both hot and cold ingredients. To use potato starch as a thickening agent, start by mixing it with a small amount of cold water to create a slurry. Then, gradually add the slurry to your lemon curd while stirring constantly.

As the mixture heats up, the potato starch will thicken the curd to a smooth and creamy consistency. Just make sure to cook the curd for a few minutes to fully activate the starch and remove any raw taste.

Agar Agar

Agar agar, derived from seaweed, is a versatile thickening agent commonly used in vegan recipes. It’s a great alternative to corn flour when you need to thicken your lemon curd.

To use agar agar, start by dissolving it in water and then adding it to your lemon curd mixture. The agar agar will help to create a smooth and thick texture without any lumps.

It’s important to note that agar agar sets at room temperature, so you’ll need to refrigerate your lemon curd for it to fully set. Additionally, agar agar is a tasteless ingredient, so it won’t affect the flavor of your lemon curd.

Give agar agar a try and enjoy the perfect consistency of your vegan lemon curd!

Xanthan Gum

To achieve a smooth and thick texture in your vegan recipes, xanthan gum is a versatile ingredient that can be used as a thickening agent. Xanthan gum, derived from fermented sugar, is a popular choice for thickening plant-based dishes. It works by trapping air bubbles, creating a gel-like consistency that adds body and viscosity to your recipes.

When using xanthan gum, a little goes a long way, so start with a small amount and gradually increase as needed. To thicken your lemon curd without corn flour, simply whisk a small amount of xanthan gum into the mixture until it reaches your desired thickness. The gum will evenly distribute throughout the curd, providing a smooth and creamy texture.

Enjoy your thickened vegan lemon curd!

Chia Seeds

Chia seeds are a versatile ingredient that can be used to add texture and nutritional value to a variety of recipes.

If you’re looking to thicken your lemon curd without using corn flour, chia seeds can be a great alternative. To incorporate chia seeds into your lemon curd, simply mix them with water and let them sit for a few minutes until they form a gel-like consistency.

Then, add this chia gel to your lemon curd mixture and stir well. The chia seeds will absorb the liquid in the curd, creating a thicker consistency.

Not only do chia seeds provide a natural thickening agent, but they also offer a host of health benefits, including omega-3 fatty acids and fiber.


Pectin can be a useful alternative for thickening your lemon curd if you’re looking to avoid using corn flour. It is a natural substance found in fruits, particularly in the skins and cores.

When heated with sugar and acid, pectin forms a gel-like texture, making it perfect for thickening jams, jellies, and yes, even lemon curd. To use pectin as a thickening agent, simply add it to your lemon curd mixture while cooking. The amount needed may vary depending on the recipe, so be sure to follow the instructions on the pectin package.

With pectin, you can achieve a thick and luscious lemon curd without relying on corn flour. Give it a try and enjoy the tangy goodness!

Coconut Flour

If you’re looking for a gluten-free alternative, coconut flour can be a great option for adding texture to your baked goods. It’s a versatile ingredient that can also be used to thicken lemon curd without corn flour.

The fine texture of coconut flour helps absorb excess liquid and gives a velvety consistency to the curd. To use coconut flour as a thickening agent, simply whisk it into your lemon curd gradually until you reach the desired thickness. The coconut flavor is subtle, so it won’t overpower the tangy taste of the lemon.

Plus, coconut flour is packed with fiber and nutrients, making it a healthier choice. So, if you’re looking to make your lemon curd gluten-free and add some texture, coconut flour is the way to go.

Rice Flour

Using rice flour in your baking can provide a gluten-free option while still adding a unique texture to your recipes.

Rice flour is made from finely ground rice and is a versatile ingredient that can be used in a variety of baked goods.

When used in baking, rice flour can help thicken your recipes and give them a slightly chewy texture.

It is particularly useful in gluten-free baking as it can provide structure and stability to your baked goods.

Rice flour can be used as a substitute for wheat flour in a 1:1 ratio, making it an easy option for those with gluten sensitivities or allergies.
