Summer is Curry Season: Here's the Science to Prove It

Every June, people who could eat curry twice a week in February stop making it entirely. The barbecue goes on, the spice rack goes untouched, and a cuisine that has been feeding people in the heat for thousands of years gets shelved until the weather turns cold again.

Kerala sits at around 28 degrees year-round. The belief of "curries are for cold-weather" doesn't stack up against that fact. The people there did not stop eating curry when the temperatures rise, and there are good reasons why.

Understanding them changes how you cook from May through September.

The connection between hot climates and spiced food has been studied formally since the 1990s. The findings are worth knowing — not because the science adds intellectual credibility to eating curry in June, but because they tell you something genuinely interesting about where the cuisine came from and why it works the way it does.

Reason 1: Heat Up To Cool Down

Capsaicin — the compound responsible for chilli heat — activates heat-sensing nerve receptors (TRPV1) in your mouth and throat. Your brain interprets this as a signal that your body is overheating and fires its cooling response: sweating, vasodilation, flushing. As that sweat evaporates from your skin, it pulls heat away from the body. The heat you feel from a good curry does not stack indefinitely. It peaks, triggers the cooling response, and passes. A cold beer alongside accelerates that considerably.

Serve it the way it was meant to be served — with the raita, the fresh herbs, the cold beer alongside — and it is one of the best things you can eat in the middle of summer.

The winter-curry association in Ireland was shaped by what arrived here first. Think of the korma that shaped the Irish idea of curry: cream-heavy, mild, built for a cold night. Its Irish iteration is itself a long way from the original. The Mughal dish it came from uses ground almonds and yoghurt, not double cream. What arrived in Ireland was already an adaptation, made milder and richer for a market that was new to spice. That version stuck, and it brought the winter association with it.

That version of the cuisine is here to stay, and it has its place. It is just not what the whole tradition looks like, and its not made for hot summer nights. So how can you tell if that curry recipe you look like works for summer? While not an exact science, heres our top indicators:

• How can I make a curry in summertime?
• Choose a lighter base — tomato, tamarind, or coconut milk rather than a cream sauce. Use what is in season: ripe tomatoes, green chillies, fresh lime, coriander. Toast whole spices (cumin, coriander, cardamom) in a dry pan for two minutes before grinding — this step makes a more significant difference than any ingredient upgrade. Add chilli heat gradually and taste as you go rather than measuring. Serve with a raita (yoghurt, cucumber, carrot) and fragrant basmati or flatbreads. A prawn and green mango curry, a Kerala coconut fish curry, or a dry-spiced chicken with fresh herbs will take 40 to 50 minutes from start to plate. All of them are better eaten outside with a cold beer.
• Why do people eat spicy food in hot countries?
• Before refrigeration, cooking with garlic, cumin, chilli, and coriander in a warm climate was how food was kept safe. The spices that built the cuisine also kept the people who cooked it healthy. Sherman called it Darwinian Gastronomy. The food encoded the biology. There is also a secondary mechanism: capsaicin triggers sweating and vasodilation, which cools the body through evaporation. Hot-climate cuisines also pair spiced dishes with yoghurt, coconut milk, and fresh herbs — a deliberate cooling architecture built into the meal.
• What are good summer curry ideas?
• The best summer curry ideas use lighter bases and fresh seasonal produce. A Kerala-style coconut fish curry is sharp, aromatic, and done in under 30 minutes — one of the most summer-appropriate dishes in the tradition. A prawn and green mango curry uses the mango's acidity the way a Thai dish uses lime, keeping the flavour alive rather than heavy. A cashew chicken noodle curry feeds a crowd with less effort than it looks. For Korean-influenced cooking, a gochujang braised chicken carries real heat but finishes clean. All of these work better eaten outside, and all of them are covered in Dublin Cookery School's Summer Curries & Beer evening class.
• What is a curry cooking class?
• A curry cooking class is a hands-on session where you cook curry from scratch — building a spice base, working with whole and ground aromatics, and cooking the dish rather than following a packet. Dublin Cookery School's Summer Curries & Beer class runs on Tuesday evenings from 7pm to 9:30pm at the school's kitchen in Blackrock, South Dublin. The class covers three summer curry dishes: hake with curried corn and lime, prawn and green mango curry, and cashew chicken noodle curry, alongside cooling accompaniments including carrot and sultana raita and kachumber salad. Classes cost €95, are suitable for all levels, and include cold beer or white wine with the meal.
• What beer goes with curry?
• A cold lager or pale ale. The carbonation matters more than the label — bubbles cut through capsaicin between bites and reset the heat, which is why the spice never builds the way it does when you drink water alongside a hot dish. A good pale ale adds hop bitterness that works against aromatic spices the same way lime does in the cooking: it sharpens the whole thing rather than competing with it. Avoid anything too sweet or too heavy — a porter or stout fights the spice rather than working with it. Temperature matters as much as style. Cold.
