Bird's eye chili substitutes

The best fresh substitute, and the easiest to find in an ordinary supermarket.

Best for

sambal and chili pastes, Thai and Indonesian curries, stir-fries, fresh salsas and dipping sauces

Serranos are genuinely hot, just not in the same league, and three of them get you close on heat. The flavour is grassier and more straightforwardly green, without the slight fruitiness a red bird's eye has. The practical catch is water: serranos have thicker flesh and more of it, so three of them add noticeably more moisture and bulk to a pounded paste than one bird's eye did. If you are making a sambal, cook the paste a few minutes longer to drive that off. Leave the seeds and pith in, since that is where most of the heat sits.

Widely available but very mild, so it takes a lot of them or a heat booster.

mild versions of Southeast Asian dishes, stir-fries, salsas, cooking for people who do not want much heat

Realistically you will not want to add eight jalapenos to a recipe: the vegetal, faintly sweet, capsicum flavour becomes obvious and the volume of flesh will dilute everything else. The better move is three jalapenos for body and flavour plus a quarter teaspoon of ground cayenne per bird's eye chili to close the heat gap. Jalapeno heat also varies enormously between individual peppers, so taste a sliver before committing. Deseeding them, which many recipes suggest, drops the heat further and is the wrong direction here.

The most accurate way to match the heat when you have no fresh chilies at all.

Best for

curries and braises, marinades and rubs, soups, sauces where texture does not matter

Cayenne sits in the same heat band, roughly 30,000 to 50,000 Scoville, so the arithmetic is easy and the result is reliably spicy. What you lose is everything else: the bright, almost fruity pop of a fresh chili, the little flecks of red and green in the finished dish, and the crunch. A cayenne-spiked curry tastes flatly hot rather than lively. Add it early with the other ground spices so it blooms in the oil instead of tasting dusty. Kashmiri chili powder is much milder and is not a swap for this.

The pantry answer, coarse and seedy rather than sharp and clean.

Best for

stir-fries, noodle dishes, chili oils, finishing heat at the table

Flake strength varies a lot between brands, so start with half the amount and taste. The heat arrives slower and lingers longer than a fresh chili's, and there is a distinct dried, slightly smoky, seedy character that reads Italian or Chinese rather than Southeast Asian. Bloom them in hot oil for twenty seconds before adding anything else, which softens the dusty edge considerably. They will leave visible flecks and seeds in a sauce that would otherwise be smooth.

Made from the same style of chili, so the flavour direction is right, but it brings extras.

Best for

stir-fries and fried rice, noodle sauces, marinades, dipping sauces

Sambal oelek is essentially crushed red chilies with salt and vinegar, and chili-garlic sauce adds garlic on top, so both land much closer to the mark than a European chili flake. Because they contain salt and acid, cut back the salt in the recipe and hold off on any lime or vinegar until you have tasted it. The texture is a wet mash, which is good for a sambal and slightly awkward if you wanted whole rings of chili floating in a clear broth.

Hotter than you need and with a distinctive flavour, so use a sliver.

Best for

very hot sambals, hot sauces, curries where fruitiness is welcome

A habanero runs 100,000 to 350,000 Scoville, so a quarter of one roughly matches a single bird's eye. The problem is not the heat but the aroma: habaneros carry a strong floral, apricot-like note that immediately makes a dish taste Caribbean or West African rather than Indonesian or Thai. In a heavily spiced rendang or curry paste you can get away with it. In a simple sambal with just chili, shallot, lime and salt, the habanero flavour will be the first thing anyone notices.
