Cooking With Alcohol: How To Keep The Booze?

Alcohol is a versatile ingredient in the kitchen, enhancing the flavour and aroma of many dishes. It is commonly used in cooking to add a burst of flavour and aroma to dishes such as coq au vin, lager-spiked turkey chilli, or pork brined in rum. Alcohol is a volatile compound, meaning it evaporates at a lower temperature than water. Despite this, not all alcohol is cooked off, and some of it remains in the dish. The amount of alcohol that remains depends on various factors, including cooking time, temperature, and the specific ingredients used. For instance, a bread crumb topping on scallops cooked in wine sauce can prevent alcohol from evaporating. This article will explore the different ways to cook with alcohol and the factors that influence the amount of alcohol that remains in a dish.

Alcohol enhances flavour and aroma

Alcohol has been a staple ingredient in many traditional cuisines, from the ancient Greeks who used wine to tenderize meat, to the French and their famous wine sauces. Cooking with alcohol is a great way to add complexity and depth of flavour to your dishes. It can enhance the taste and aroma of a dish, and even make your dishes smell more appetizing.

The volatile molecules in alcohol evaporate not just when it reaches its boiling point, but any time it is exposed to air. However, it is impossible to cook out all of the alcohol in a dish. A small proportion of its molecules will remain bonded to molecules like water present in the mixture. The amount of alcohol that remains depends on several factors, including the recipe's other ingredients, the temperature it is cooked at, and the length of time for which it is cooked. The higher the temperature and the longer the cooking time, the greater the evaporation.

Different types of alcoholic beverages contribute different elements to a dish's flavour profile. For instance, white wine is widely used for all kinds of recipes but is particularly suitable for cooking lighter meats, chicken, fish, mushrooms, and pork. Drier, more acidic wines, such as Pinot Grigio, Sauvignon Blanc, and Pinot Blanc, are best for cooking. Red wine, on the other hand, is recommended for pasta sauce, stew, or beef. Merlot, Pinot Noir, and Cabernet are wines with higher acidity that will bring out memorable flavours in your food.

Beer is another alcoholic beverage that can be used in cooking. It can add intensity and complexity to a dish's flavours. It is often used to simmer meat, vegetables, and potatoes, and can also be used in baking bread, biscuits, and more. Most of the alcohol evaporates during cooking, leaving primarily nutty, earthy notes and a distinct caramelized taste. Whiskey, vodka, and rum are other types of alcohol that can be used in cooking to enhance the flavours of a dish.

Alcohol doesn't fully evaporate when cooked

The type of dish and cooking method also influence the amount of alcohol that evaporates. For instance, flambéing, which involves setting food doused in alcohol on fire, is a cooking technique that promotes alcohol evaporation. On the other hand, dishes that require stirring during the cooking process tend to have lower alcohol evaporation rates. The size of the pan also matters; a larger pot with a greater surface area allows more alcohol to evaporate compared to a smaller pan. The number of ingredients in a dish can also affect alcohol evaporation, as the interactions between various ingredients can hinder the evaporation of alcohol.

The original alcohol content of the liquor used in cooking also determines how much alcohol remains after cooking. For example, using rice wine in a dish will result in a lower alcohol content compared to using spirits or liquors with higher alcohol by volume (ABV). While the alcohol content decreases over time, it is challenging to eliminate it entirely. Therefore, it is advisable to consider non-alcoholic alternatives when preparing meals for children, pregnant women, or individuals who abstain from alcohol for health, cultural, or religious reasons.

Factors influencing the amount of alcohol retained

Several factors influence the amount of alcohol retained in cooked dishes. Firstly, the cooking time or duration of heat exposure significantly impacts alcohol retention. Generally, the longer the cooking time, the greater the alcohol loss through evaporation. For instance, baked or simmered dishes containing alcohol retain about 40% of alcohol after 15 minutes, 35% after 30 minutes, 25% after an hour, 10% after two hours, and 5% after two and a half hours. However, to completely eliminate alcohol, one study suggests that cooking for about three hours is necessary.

Secondly, the cooking temperature plays a role, with higher temperatures resulting in quicker evaporation. The boiling point of alcohol is 173 degrees Fahrenheit, and cooking at or above this temperature will cause alcohol to evaporate rapidly. Therefore, flaming or applying high heat to a dish will result in greater alcohol loss than cooking at lower temperatures.

Thirdly, the size of the cooking vessel and the surface area exposed to air affect alcohol retention. Smaller pots or pans with smaller surface areas allow less opportunity for alcohol molecules to escape, retaining more alcohol in the dish. Consequently, a larger pot or pan with a larger surface area will result in greater alcohol evaporation.

Additionally, the number and type of other ingredients in the recipe can influence alcohol retention. Certain ingredients, such as sugar, flavours, and solid foods, can interact with alcohol and make it more challenging to cook off. Furthermore, a bread crumb topping on a dish cooked in wine sauce can prevent alcohol evaporation, increasing the final alcohol content. Stirring during the cooking process can also promote evaporation, leading to lower alcohol retention.

Lastly, the initial concentration of alcohol in the dish and the cooking method used, such as baking, simmering, or flaming, will also impact the final alcohol content. For example, dishes flamed with alcohol retain about 75%, while those simmered or baked for 15 minutes with stirring retain about 40%. It is worth noting that while cooking reduces alcohol content, it is challenging to eliminate it entirely, and some alcohol will always remain in the dish.

Substitutions and alternatives to alcohol in cooking

Alcohol is often used in cooking to add flavour and aroma to dishes. However, there are several reasons why one might want to avoid using alcohol in cooking. The good news is that in almost all recipes that call for alcohol, the purpose is to add flavour. Therefore, it is possible to make substitutions and alternatives to alcohol in cooking without sacrificing flavour.

Firstly, it is important to note that the more ingredients mixed in with an alcoholic drop, the harder it may be to 'cook off' the alcohol in your dish. Therefore, if you are trying to avoid alcohol altogether, it is recommended that you boil the alcoholic beverage on its own first, heating it to the point that it is bubbling, before you add it to other ingredients. Additionally, slow cooking a dish with a lid and occasionally raising the lid to let out accumulated vapour can help burn off ethanol.

When substituting alcohol in recipes, it is the flavour profile, not the booze, that is most often essential to the success of the dish. For example, wine adds a bit of sweetness to a dish. Therefore, grape juice, pomegranate juice, or tomato juice can be used as a non-alcoholic equivalent. To replace the sweetness of wine, a small amount of honey or sugar can be added to the juice. For white wines, apple juice can be used to add a sweet acidity without overpowering the dish. Lemon juice or lime juice can also be used as alternatives to white wine. Chicken or pork stocks can also be used as alternatives to wine, but more may be needed to get the desired flavour.

For those who want to avoid the flavour of alcohol altogether, unfermented products such as grape juice, malt extract, and barley syrup can be used. For pie crust recipes that call for vodka, more ice water can be used as a substitute. Alcohol-free spirits are also on the rise, with brands such as Seedlip offering alternatives to gin. For beer, alcohol-free beer can be used, or sparkling water if it is a beer batter. For red wine, beef broth can be used as a substitute, and chicken broth can be used as a lighter substitute for white wine. For smaller amounts, such as when deglazing a pan, a splash of vinegar or cider can be used.

Alcohol in cooking for those abstaining

Alcohol is often used in cooking to add flavour and aroma to dishes. However, this can be problematic for those who abstain from alcohol for personal, health or religious reasons. It is important to note that alcohol never fully evaporates during the cooking process, only reducing in quantity. Therefore, it is not suitable for consumption by those abstaining from alcohol.

The amount of alcohol that remains in a dish depends on various factors, including the type of alcohol used, the cooking method, the size of the pan, and the cooking time. For example, dishes cooked in a wider and larger pan will have more surface area exposed, allowing more alcohol to evaporate. Stirring the dish during cooking will also promote evaporation. The cooking method also plays a significant role, with baking or simmering dishes retaining 40% of alcohol after 15 minutes, 35% after 30 minutes, and 25% after an hour. Even after two and a half hours, 5% of alcohol content still remains.

The type of alcohol used also affects the final alcohol content of the dish. Alcohol with a higher ABV, such as rum, will result in a dish with a higher alcohol content compared to using beer, which typically has a lower ABV. Marinades that are not cooked can retain up to 70% of alcohol, while dishes flamed or flambéed can retain 70-75% of alcohol content.

It is important to be cautious when serving dishes containing alcohol to guests, especially those who abstain from alcohol. While a final alcohol content of 10% or less may not affect most adults, it can be an issue for children and those abstaining. For those who are in recovery, pregnant or breastfeeding, or abstaining for religious or health reasons, it is best to avoid recipes that include alcohol as an ingredient.

There are alternatives to using alcohol in cooking. For example, non-alcoholic wines, spirits, and beers can be used as substitutes to add flavour without the alcohol content. Additionally, certain ingredients can be used to enhance flavours in dishes that traditionally use alcohol. For instance, vanilla extract can be used in desserts, while broth or stock can be used in savoury dishes.
