Curex is the place to go for all your allergy questions and needs. Led by healthcare entrepreneurs and allergy clinicians, Curex is an integrated, online telemedicine clinic for people who suffer from environmental allergies (e.g., indoor, outdoor or pet), asthma, and eczema.

Curex is the largest online allergy and asthma clinic in the U.S. We started because our clinicians wanted to offer more convenient and affordable allergy and asthma care for everyone. So far we have attracted more than 50,000 customers from every U.S. state. We are proud to have the highest patient satisfaction and loyalty rates in the industry. Our service has been audited and certified by LegitScript.com.

What services do you offer?

Curex provides comprehensive care for those suffering from allergies, asthma, and eczema. This includes customized sublingual immunotherapy, at-home concierge allergy testing, and symptom management. Our goal is to provide accessibility and quality of allergy care in the U.S.

Does Curex accept insurance?

Curex accepts the majority of insurance plans across the United States, including Aetna, Anthem, United, Humana, and others. While it is difficult to estimate out-of-pocket costs prior to a claim being submitted, our team will work with you to make sure your treatment is as affordable as possible. For that purpose, we also cap copays at $500/year. In addition, Curex accepts HSA and FSA.

What conditions do you treat?

We focus on indoor and outdoor allergies caused by environmental or inhalant allergies, like those caused by pollens, weeds, grasses, dust mites, molds, and pets. We also treat allergic asthma and eczema, as these conditions are closely related to allergies.

What is immunotherapy?

Immunotherapy is a longstanding form of treatment that aims to meaningfully reduce the underlying cause of indoor/outdoor allergies and related conditions. It is frequently practiced by using allergen extracts for shots or allergy tablets. Treatment plans are customized to the individual patient based on medical profile, test results, and lifestyle needs.

Can my child use Curex?

Curex serves adults and children as young as 5 years old. Certain tests and treatments may be limited for younger kids. Start by answering the quiz, so that our clinicians can recommend the best testing and treatment options.

Does Curex treat food allergies?

Curex currently treats allergies to tree, weed, grass pollens, pet allergies, dust mites, mold, and cockroach. We do not treat food, metal, venom, or flower allergies.

What is your cancellation policy?

Treatments are shipped in 3-month installments in all plans. Cancellations are accepted prior to the next refill being compounded by the pharmacy (so you can get a partial refund on a prepayment plan). To cancel or pause subscriptions, please email our team at hi@getcurex.com.

How does allergy testing work?

Depending on your location, we send a phlebotomist (medical assistant) to your home or office for a simple blood draw (not a finger prick). This sample is then processed using hospital-grade technology to produce accurate results. In some areas, you may need to go into a local lab for your blood draw. We work with LabCorp and Quest Diagnostics. This is an IgE blood test that results in more accurate results compared to finger prick tests that are available online through some companies. This is not a skin scratch test where an allergist spends 30+ minutes injecting you with small doses of allergens to see if any swelling or reaction occurs.

Is sublingual immunotherapy safe?

Studies have shown a significantly lower risk for anaphylaxis relative to allergy shots, allowing you to take them in the comfort of your own home. If recommended by your Curex-affiliated clinician, or if you prefer, your first dose may be monitored to ensure proper usage. Clinicians will also assist in helping you manage any side effects that you may experience.

Servings: 8

Prep Time: 15 minutes

Total Time: 2 hours 15 minutes (including chilling)

Rating: 4.8 from 62 votes

Equipment

8-inch round cake pan
Medium saucepan
Larger baking dish for a water bath
Blender
Refrigerator

Ingredients

For the caramel:

1 cup granulated sugar
1/4 cup water

For the flan:

1 can (13.5 oz) coconut milk (ensure it’s free from allergens you might be sensitive to)
1/2 cup organic cane sugar
1/2 cup unsweetened applesauce
1 tablespoon vanilla extract
1/4 cup cornstarch
Pinch of salt

Instructions

Preheat your oven to 350°F (175°C).
Make the caramel: In a medium saucepan, combine the sugar and water over medium heat. Stir until sugar dissolves. Stop stirring and let it simmer until it turns a deep amber color, approximately 8-10 minutes.
Carefully pour the hot caramel into the bottom of the cake pan, tilting it to spread evenly. Be cautious as the caramel will be very hot.
Prepare the flan mixture: In a blender, combine the coconut milk, cane sugar, applesauce, vanilla extract, cornstarch, and salt. Blend on high until the mixture is completely smooth.
Pour the flan mixture over the caramel in the cake pan.
Place the cake pan inside a larger baking dish. Fill the larger dish with hot water halfway up the sides of the cake pan to create a water bath.
Bake in the oven for 50-60 minutes, or until the flan is set around the edges but still slightly wobbly in the middle.
Carefully remove the cake pan from the water bath and let it cool to room temperature. Then, refrigerate for at least 2 hours, or until completely chilled.
Once chilled, run a knife around the edges of the flan to loosen it. Place a serving plate with a rim over the cake pan and gently invert the flan onto the plate.
Serve chilled and enjoy your allergen-free caramel flan!

Caramel flan Recipe Troubleshooting

1. Why is the caramel not turning out deep amber?

Possible Reasons for Caramel Not Turning Deep Amber

Temperature: The temperature might be too low. Caramel needs to be cooked at a consistent, medium-high heat to achieve the deep amber color.
Timing: It may not have been cooked long enough. Caramel can take time to reach the desired color and flavor.
Moisture: Too much water or humidity can prevent sugar from caramelizing properly.
Stirring: Stirring the mixture after the sugar has dissolved and started to boil can cause crystallization, preventing a deep amber color.
Pan Type: Using a pan with a thin bottom may cause uneven heating, making it harder to achieve a uniform caramelization.

2. What causes the flan to set unevenly?

What causes the flan to set unevenly?

Improper Mixing: If the flan mixture is not properly mixed, it can result in uneven setting due to ingredients not being evenly distributed.
Temperature Fluctuations: Sudden changes in temperature during cooking or cooling can cause the flan to set unevenly.
Incorrect Water Bath: Failing to use a proper water bath or allowing water to evaporate may cause uneven cooking and texture.
Uneven Oven Heat: An oven that doesn't heat evenly can lead to irregular setting of the flan.
Overcooking: Cooking the flan for too long can cause it to set unevenly as the edges may firm up faster than the center.

3. Why is the flan mixture not blending smoothly?

Why is the flan mixture not blending smoothly?

Incorrect Mixing Ratio: Ensure you're using the correct quantities of each ingredient. A disproportion of thickening agents like cornstarch or sugar might hinder smooth blending.
Insufficient Blending Time: Blend the mixture on high for an adequate amount of time to ensure all components are fully integrated.
Temperature of Ingredients: If ingredients like coconut milk and applesauce are at very different temperatures, they may not blend well. Use room temperature ingredients for better consistency.
Power of the Blender: A less powerful blender might struggle to achieve a smooth texture. Consider using a high-speed blender for better results.
Clumping of Ingredients: Ingredients like cornstarch may clump together if not added carefully. Sifting dry ingredients or mixing them slowly can help prevent clumps.

4. What makes the flan too firm after chilling?

Reasons for Flan Being Too Firm After Chilling

Excessive Use of Thickening Agents: Overusing cornstarch or other thickening agents can make the flan overly firm.
Overcooking: Baking the flan for too long or at too high a temperature can result in a firm texture.
Incorrect Ingredient Ratios: Not maintaining the correct ratio of liquids to solids impacts the desired creamy consistency.
Inadequate Caramel Spread: Uneven distribution of caramel can affect the overall texture.

5. Why does the caramel stick to the pan?

Why Does the Caramel Stick to the Pan?

Temperature: Caramel hardens quickly as it cools, and a significant temperature difference between the caramel and the pan can cause it to stick.
Moisture: If there's not enough moisture left in the caramel, it can become too sticky and adhere to the surface of the pan.
Type of Pan: Some materials, such as stainless steel, might cause caramel to stick more than non-stick or silicon surfaces.
Lack of Grease: Not greasing the pan before pouring the caramel can make it stick more firmly.
Sugar Type: Different types of sugar can crystallize or behave differently, influencing how sticky the caramel may be.

6. What makes the flan's texture gritty or lumpy?

Causes of Gritty or Lumpy Flan Texture

Improper Mixing: Failure to fully dissolve sugar in the milk or cream mixture can lead to a gritty texture.
Overcooking: If flan is baked too long or at too high a temperature, it may become lumpy. This often causes proteins in the eggs to toughen, affecting the texture.
Poor Quality Ingredients: Using low-quality or impure sugar can result in undissolved particles contributing to a gritty texture.
Insufficient Straining: Not straining the flan mixture before baking can leave small bits of egg or other ingredients, leading to a lumpy consistency.
Caramel Issues: If the caramel isn’t smooth when it’s poured into the mold, it can crystalize, creating a gritty layer at the bottom.
