Methods for creating a thicker sauce

Cornflour/Corn Starch

Cornflour, also known as corn starch, is a commonly used thickening agent in sauces and curries. The fine, white powder is derived from the endosperm of a corn kernel and has a neutral taste, so it won’t alter the flavor of your dish. To effectively thicken a curry with cornflour or corn starch, start by mixing it with a small amount of water to create a slurry. This step is essential to prevent the cornflour from clumping when added to the hot curry. Once your slurry is smooth and well combined, gradually stir it into your simmering curry. The heat will cause the cornstarch to expand, thickening the sauce. Remember to add the slurry slowly and stir constantly to achieve your desired consistency.

Using Flour

Flour is another excellent option to thicken a curry in your slow cooker. To use flour as a thickening agent, you first need to make a roux. Start by melting some butter or heating oil in a pan. Next, add an equal amount of flour to the melted butter or oil, stirring continuously to create a smooth paste. This is your roux. Cook the roux for a few minutes to remove the raw taste of flour. Once your roux is ready, gradually add it into your hot curry sauce, stirring constantly. The flour in the roux will absorb the liquid in the curry and thicken the sauce. As with cornstarch, add the roux slowly and stir continuously to achieve the desired consistency.

Using Potatoes

Potatoes, a staple in many kitchens, can also serve as a natural thickening agent for your curry. The starch content in potatoes is released when they are cooked, which can help to thicken your curry sauce. Start by peeling and cutting the potatoes into small cubes, then add them to your curry. As they cook, the potatoes will break down and release starch, thereby thickening the sauce. However, keep in mind that the starch content in potatoes may not be sufficient to thicken a curry with excessive liquid. Thus, this method is best utilized when you are planning to incorporate potatoes into your curry recipe and are looking to slightly thicken the sauce rather than achieve a very thick consistency.

6 tips to thicken a curry in a slow cooker

Curry is a popular dish that’s enjoyed by many people all around the world. It’s packed with flavor, and it can be customized to suit different preferences and dietary restrictions. One of the best things about curry is that it can easily be made in a slow cooker, which means you can set it and forget it while going about your day. However, if you want a thicker curry, you might run into some challenges when using a slow cooker. In this guide, we’ll share five tips to help you thicken your curry while cooking it in a slow cooker.

1. Use less liquid

One of the easiest ways to thicken your curry is by using less liquid. Slow cookers are designed to trap steam and moisture, which is great for keeping your food moist and tender. However, it can also lead to a thinner consistency in your curry. To counter this, try using less liquid in your recipe than you normally would if cooking on the stovetop. This will help the sauce thicken as it cooks.

2. Pre-cook some ingredients

Another way to achieve a thicker curry is by pre-cooking some of the ingredients before adding them to the slow cooker. This will help release their natural starches and thicken the sauce. For example, you can pre-cook onions, garlic, or vegetables in a pan with some oil before adding them to the slow cooker.

3. Add a thickening agent

If you want to thicken your curry even more, you can add a thickening agent to the slow cooker. Some common options include cornstarch, flour, or arrowroot powder. Mix the agent with some water or broth before adding it to the slow cooker towards the end of the cooking time. This will help prevent clumping and ensure an evenly thickened sauce.

4. Use a potato or root vegetable

Another natural thickening agent for curry is potatoes or other root vegetables like carrots or parsnips. These vegetables release starches as they cook, which will help thicken the sauce. Simply chop them into small pieces and add them to the slow cooker at the beginning of the cooking time.

5. Leave the lid off

If your curry is still too thin after cooking, you can try leaving the lid off for the last 30 minutes to an hour. This will allow some of the moisture to evaporate and thicken the sauce. Just be careful not to leave it off for too long, as this can also lead to over-reduction and a concentrated flavor.

6. Use a slotted spoon

If all else fails and your curry is still too thin, you can try using a slotted spoon to remove some of the excess liquid. This will help concentrate the sauce and make it thicker without altering the flavor too much. Just be careful not to remove too much liquid, as this can also make the dish dry.
