How to grow Chilli Pepper (Super Hot)
in the UK
Sow January to March, plant out April to July, harvest August to October. About 100 days from seed to plate.
Chilli peppers, especially these super hots, are a proper challenge on the allotment, like I say, they're not for the faint-hearted. But there's nothing quite like the feeling of growing your own fiery chillies, especially up here in the North East where the weather's not always on our side. They demand a bit of fussing, but the rewards are well worth it, you'll be chuffed.
Sowing
You need to get these seeds going proper early, January, February, or March really, to give them a fighting chance. Sow them indoors, just a few millimetres deep in small pots or modules, then pop them on a heat mat or in a propagator set between 20-27°C. They need grow lights too, to be honest, otherwise they'll get leggy and weak before spring even arrives, you know what I mean. Consistent warmth is key for these fussy buggers right from the start.
Growing on
Once your seedlings have a couple of true leaves, carefully prick them out and pot them on into individual small pots. Keep them warm and well-lit. Now, they're tender plants, so don't even think about planting them outside until all danger of frost is gone, usually mid to late May up here. A greenhouse is definitely their happy place, giving them the heat and shelter they crave, planting them 45-60cm apart. You can grow them in decent-sized pots too, if you're short on space.
Looking after it
Chilli plants like a steady hand with the watering can; don't let them dry out completely, but don't drown them either. Once they start to flower and set fruit, give them a regular feed with a tomato fertiliser every week or two. Pinching out the tops can encourage bushier growth, but with super hots needing such a long season, sometimes it's best just to let them crack on, to be honest.
What goes wrong
Like most greenhouse plants, you've got to keep an eye out for aphids, red spider mites, and whitefly. They just love the warm, sheltered conditions. Regular checks are your best bet; squish what you see, or give them a good spray with some soapy water. A healthy plant is always better at fighting off the nasties, like I say.
Harvest
Your chillies will be ready to pick from August right through to October, once they've reached their full size and proper colour. Always handle these super hots with gloves, even when picking, trust me. You can store them in the fridge for a week or two, freeze them whole, or dry them out to make your own chilli powder. A cracking harvest is a proper joy.

Don't be tempted to plant these outside up here in the North East, they just won't get the warmth they need, stick 'em in the greenhouse for a proper harvest.

Cook the harvest
Dubu jorim is a Korean home staple — firm tofu pan-fried until golden then braised in a sticky, intensely spiced sauce. This version uses fresh super hot chilli alongside gochujang and gochugaru to build a layered, complex heat that is far more interesting than simple spice. The sauce lacquers the tofu as it reduces, giving you crispy-edged pieces glazed in something genuinely addictive.
40 min · mediumCharred corn on the cob slathered with a super hot chilli compound butter that melts into every kernel — this is one of those absurdly simple things that is greater than the sum of its parts. The butter carries the chilli heat right through the corn as it melts, and a squeeze of lime and some flaky salt finish it perfectly. This is on the table in under 25 minutes.
25 min · easyA proper rendang takes time and patience, and this one rewards both generously. The super hot chillies are blitzed into the spice paste and cooked low and slow with coconut milk until the beef is meltingly tender and the sauce has reduced to a dark, clinging, intensely flavoured coating. This is the kind of dish that gets better the next day.
180 min · challengingThis is a shakshuka where the chillies are the main event, not the background warmth. Super hots are roasted alongside late-summer tomatoes until they blister and sweeten, then the whole lot is blended into a deep, smoky, ferociously flavoured sauce. Eggs are poached directly in the sauce and served with plenty of bread for mopping.
