The Guajillo chilli plant brings one of the most important Mexican drying chillies straight to your own garden. The fully ripe red fruit is traditionally dried, creating the typical deep, fruity-spicy Guajillo aroma. Botanically, Guajillo belongs to Capsicum annuum.
How hot is Guajillo chilli?
Guajillo sits at around 2,500–5,000 Scoville Heat Units (SHU). That keeps the heat pleasantly in the background and leaves plenty of room for the aroma. This mild Scoville value places Guajillo in the mild chilli plants with heat level 0–3 category.
Fresh Mirasol, dried Guajillo
With Mexican chillies, the well-known name often refers to the dried fruit. Guajillo comes from fully ripe red fruit of the Mirasol type. After drying, the pods are often briefly toasted, soaked and processed for mole, adobo, marinades or braises. Fresh, Guajillo tastes mild, lightly fruity and spicy; dried, depending on preparation, its aroma recalls red fruit, tea and warm spice notes.
Harvesting and drying Guajillo
The slender, mostly smooth-skinned fruit grows about 10–15 cm long and ripens from green to deep red. For typical Guajillo use, let the fruit ripen as fully as possible on the plant before drying it. Our guide on how to dry chillies explains which method works best.
Growing Guajillo in a pot
The plant grows upright to bushy and reaches about 60–100 cm. We recommend a full-sun, warm and sheltered spot and at least 8, ideally 10 litres of pot volume, or more if you have the space. Use a loose, nutrient-rich substrate, avoid waterlogging and feed moderately while the plant sets fruit. Overwintered frost-free, Guajillo can also be grown for several years.
Guajillo from our growing
We grow Guajillo ourselves in Illmitz and use the variety for our Chilicrack too. As a second classic Mexican drying chilli, Ancho Poblano pairs excellently with it.
