Reducing a liquid in a pan is a simple way to add flavour and improve the texture of your dish. It involves simmering or boiling a liquid until its volume shrinks, leaving behind a thicker sauce with a more intense flavour. This technique is often used to make gravy or to thicken sauces, and it can be done with a variety of liquids, such as broth, wine, or juice. The process is simple: bring your liquid to a boil in a wide, uncovered pan, then lower the heat and let it simmer until it reaches your desired consistency. While reducing, it's important to avoid high heat as this can lead to over-reduction and a bitter taste. Instead, be patient and let the liquid slowly simmer, using a wide pan to maximise the surface area and speed up the evaporation process.

What You'll Learn
Use a wide pan to maximise evaporation
When reducing a liquid, the wider the pan, the better. A larger surface area allows your sauce to reduce more quickly. A wide, uncovered pan or pot will allow for rapid evaporation.
If you're reducing a small amount of liquid, a wide pan is especially important. For example, if you're reducing less than 1 cup (236 millilitres) of liquid, you'll need to keep a close eye on it as it reduces. A wide pan will help you achieve the desired consistency faster.
If you're reducing a large amount of liquid, a wide pan will also speed up the process. For instance, if you're making a large batch of braised short ribs, you can discard some of the liquid before you begin reducing. Using a wide pan will help the remaining liquid evaporate more quickly.
In general, a wide sauté pan or a Dutch oven is your best option for reducing liquids. These pans provide a larger surface area, which speeds up the evaporation process. So, if you're looking to maximise evaporation when reducing liquids, be sure to reach for a wide pan.

Avoid high heat to prevent over-reduction
When reducing a liquid, it is important to avoid high heat to prevent over-reduction. While it may be tempting to crank up the heat and let the water boil off, doing so can lead to an over-reduced, bitter-tasting sauce. Not only will the sauce be unappetizing, but you also risk burning whatever else is in the pan, leaving a sticky, burnt coating that can be difficult to clean.
Reducing a liquid is a delicate process that requires patience. By simmering the liquid over medium heat, you allow the water to gently evaporate, concentrating the flavours and thickening the sauce. This technique is like using a magnifying glass in cooking—it intensifies the flavours and gives you a more concentrated, flavourful sauce without the excess water.
The goal is to create a thick reduction by evaporation, and this takes time. It's important to resist the urge to turn up the heat, as this can lead to an uneven reduction and an unpleasant bitterness. A good reduction should be thick enough to coat the back of a spoon without dripping—this is known as nappant in French.
Additionally, the type of pot or pan you use can impact the reduction time. Using a wide, shallow pan with a large surface area will speed up the process by maximising the amount of liquid exposed to the air. A small, narrow pot, on the other hand, will take longer since the liquid is deeper and has less surface area to evaporate.
In summary, when reducing a liquid, avoid high heat and be patient. Simmer your liquid over medium heat in a wide, shallow pan, and you'll achieve a delicious, thick sauce without over-reducing or burning your creation.

Remove meat to prevent overcooking
When reducing liquid in a pan, it's important to remove meat chunks and slices as this can lengthen the time of the sauce reduction. If you're working with a braise, remove the meat pieces to another pan or a plate when they're done cooking, and then add them back into your reduction when it has reached the consistency you desire. This is a good way to prevent overcooking your meat.
- Boil your liquid, then reduce the heat to a simmer.
- Avoid covering the pan as the purpose of a reduction is to allow excess liquid to evaporate.
- Monitor your reduction closely, especially if it requires a small amount of liquid to start.
- Use the widest possible pan as a larger surface area allows your sauce to reduce more quickly.
- Add a tablespoon or two of butter after the reduction is done. This will thicken the reduction and give it a pleasing appearance.

Discard excess liquid to speed up reduction
Discarding excess liquid is a great way to speed up the reduction process without sacrificing flavour. If you're in a hurry, you can simply discard some of the liquid before you begin reducing. This is especially helpful if you have a large volume of liquid to begin with.
For example, if you want 2 cups (473 milliliters) of sauce, you can start with 3 or 4 cups (709 to 946 milliliters) of liquid and discard the rest. This way, you won't have to wait for a large volume of liquid to evaporate, and you can achieve your desired consistency faster.
It's worth noting that the precise amount of liquid you'll need to reduce will depend on the contents of the liquid and the conditions under which you reduce it. So, it might take a bit of experimentation to find the perfect amount for your specific recipe.
Additionally, make sure to use a wide pan or pot when reducing to maximise the surface area and speed up the evaporation process. And remember, reducing liquid is a simple and effective way to intensify flavours and create thicker, more impressive sauces.

Thicken with a slurry if the reduction is too watery
A slurry is an easy way to get a thicker, more luxurious sauce. It is almost the opposite of a roux. Unlike a roux, a slurry is uncooked, needs no fat, and is added at the end of cooking.
To make a slurry with flour, use 1 to 4 tablespoons of all-purpose flour depending on the amount of food you're cooking and how thick you'd like it to be. For a small amount of sauce, use 1 tablespoon, and for a large stew or soup, use up to 4 tablespoons. Add the flour to a small mixing bowl and pour in about 1 cup of hot cooking broth. Whisk the mixture until it is completely combined. Then, slowly pour the slurry into the pot while the stew is hot, whisking continuously. Keep stirring the stew until the mixture starts to thicken.
You can also make a slurry with cornstarch. Use 1 to 4 tablespoons of cornstarch, depending on the amount of food and desired thickness. For a small amount of sauce, use 1 tablespoon, and for a large stew or soup, use up to 4 tablespoons. Add the cornstarch to a small mixing bowl and pour in about 1 cup of hot cooking broth. Whisk the mixture until it is completely combined. Then, slowly pour the slurry into the pot while whisking and continue stirring until the mixture thickens.

Frequently asked questions
Reducing a liquid means simmering or boiling it until its volume shrinks, leaving a thicker sauce with a more concentrated flavour.
First, bring your liquid to a boil in a wide, uncovered pan. Then, lower the heat to a simmer and stir occasionally until the liquid reaches your desired consistency.
The time it takes to reduce a liquid depends on the amount of liquid, the stove's power output, and the characteristics of the pan. A reduction can take anywhere from 15 to 30 minutes or more.
If your liquid isn't reducing, try using a wider pan to increase the surface area and speed up evaporation. Avoid high heat, which can cause the liquid to over-reduce or burn.
Yes, you can reduce the liquid ahead of time and store it in the fridge until you're ready to use it. This can help ensure that all components of your meal are ready at the same time.
