Cooking with whisky

Whisky is a seasoning, so use it like one

Cooking with whisky is about aroma. Heat drives off much of the alcohol and some of the volatile flavours, so the delicate notes you pay for in a fine single malt mostly vanish in a pan. What survives is the backbone: vanilla and caramel from oak, dried fruit from sherry casks, smoke from peat.

That is why a sound, well made blended whisky is usually the right bottle for cooking. Save the rare stuff for the glass. Pick the style by the job: a bourbon or sherried blend for sweet dishes, a peated whisky for smoky marinades, a light grain whisky where you only want a lift.

Marinades and tandoori work

A spoonful or two of whisky in a marinade adds depth and helps carry flavour. In a tandoori style marinade of yoghurt, ginger, garlic, chilli and garam masala, try about 15 ml of whisky per 500 g of meat or paneer. A peated whisky gives a smoky edge that suits the char from a tandoor or a grill.

Alcohol dissolves some flavour compounds that water and fat do not, so whisky can help spices work into the surface. Do not overdo it. Too much alcohol in a long marinade can start to change the texture of the surface, especially on fish and prawns.

Whisky shines where sugar and fat meet

Whisky shines where sugar and fat are present. Some reliable uses:

• Glazes for chicken, pork or roasted vegetables: whisky, jaggery or brown sugar and a little butter reduced until sticky.
• Pan sauces: deglaze the pan after searing meat with a splash of whisky, then add stock or cream and reduce.
• Christmas cake and plum cake: many Indian home bakers soak dried fruit in rum or brandy for weeks. A sherried whisky works the same way.
• Desserts: a few drops in a caramel sauce, chocolate mousse or kulfi mix. Bourbon and its vanilla notes pair naturally with chocolate.

How much alcohol actually stays in the food

People often assume all the alcohol cooks off. It does not. A short flambe or a quick reduction leaves a large share behind. Longer simmering removes more, but even a dish simmered for an hour or more can still keep a small amount. Baked goods soaked after baking, such as a fed fruit cake, keep most of the alcohol they absorb.

So treat whisky food like a drink for anyone who should not have alcohol: children, people who avoid it for religious or personal reasons, anyone driving and anyone who has asked. Tell guests when a dish contains whisky. It is a simple courtesy and saves an awkward moment.

Flambe without setting the kitchen alight

Flambe looks theatrical and adds a light caramelised note, but it is the part of whisky cooking that sends people to hospital. Whisky at 40% ABV gives off flammable vapour at kitchen temperatures. Warm it and there is far more.

• Never pour straight from the bottle into a hot pan. Flame can travel up the stream into the bottle.
• Measure the whisky into a cup first, take the pan off the heat, add it, then return the pan and light it with a long lighter.
• Keep your face back, turn off the extractor hood if it is directly above and keep a lid nearby to smother the flame.
• Use no more than 30 to 60 ml for a home pan.

Common mistakes in the pan

Most whisky dishes that go wrong fail in one of a few ways:

• Adding it too late. Whisky stirred into a finished sauce tastes raw and boozy. Give it a few minutes of simmering so the harshest alcohol notes cook off.
• Adding too much. A tablespoon or two is plenty for a sauce for four. More turns bitter as it reduces.
• Reducing peated whisky hard. Concentrated peat can taste medicinal. Use it in marinades rather than long reductions.
• Skipping the taste test. Taste the whisky neat first, then the dish as it cooks, so you know what the whisky brought.

Measure with a spoon or a jigger rather than pouring by eye. It keeps both the dish and the cook in better shape.

Choose the style by the dish

A rough guide by dish:

• Sweet sauces, cakes and desserts: bourbon or a sherry cask whisky.
• Smoky marinades and grilled meat: a medium peated malt or blend.
• Light dishes and seafood: a grain whisky or a light blended Scotch.
• Spiced Indian dishes: a fruity blend that will not add bitterness when reduced.

Knowing what a whisky smells and tastes of before you cook with it is half the skill. Our guide on malt, grain and blended whisky explains why those categories taste different. Your first step: make one simple whisky caramel, taste the whisky neat first, then taste what survives in the sauce.

Common questions

Does the alcohol cook out of whisky in food?

Not completely. Short cooking such as flambe leaves a lot of alcohol behind. Long simmering removes more but rarely all of it.

What whisky is best for cooking?

A sound blended whisky for most dishes. Bourbon or sherried whisky suits desserts. A peated whisky suits smoky marinades.

Can I use expensive single malt for cooking?

You can, but heat destroys much of what makes it special. Keep the fine bottle for drinking and cook with something affordable.

Is it safe to flambe whisky at home?

It can be if you measure the whisky away from the stove, take the pan off the heat before adding it and keep a lid nearby. Never pour from the bottle into a hot pan.
