Few chili names cause as much confusion as these two. The aji limo and the aji limón — better known as the lemon drop pepper — are both bright, citrusy Peruvian chilies with nearly identical “aji” names, and they’re routinely mistaken for each other. But they’re genuinely different peppers, from different species, at different heat levels. Here’s how they differ and how to tell them apart.

Which is hotter, the aji limo or the aji limón?
The aji limo is the hotter of the two. It runs 30,000 to 50,000 Scoville heat units, while the aji limón (lemon drop) sits at 15,000 to 30,000 SHU. So the aji limo is roughly twice as hot, pod for pod. Both are firmly in medium-hot territory, a step or two above a jalapeño but well short of a habanero. If heat is your deciding factor, the aji limo pushes harder; the lemon drop is the gentler introduction.
Why the names get confused
This is the heart of the mix-up. “Limo” and “limón” both point to the same citrusy quality, and in different regions and markets the labels get swapped freely. But botanically they part ways: the aji limo is a Capsicum chinense, the same species as the habanero, while the aji limón / lemon drop is a Capsicum baccatum, the branch that includes aji amarillo. Same citrus theme, different family tree — which is exactly why they taste related but not identical.
How does each taste?
Both land in our Fruity & Tropical flavor family, so this is a comparison of accents within a shared bright, citrusy character rather than two different worlds.
The aji limo leans on its chinense heritage: fruity and floral, with a tropical depth under a lemony top note. The lemon drop is cleaner and sharper — its name is well earned, delivering a crisp, almost candied lemon flavor with a touch of fruity sweetness and less of the aji limo’s floral, tropical roundness. Put simply, the aji limo is the more perfumed and complex of the two; the lemon drop is the more purely, brightly lemon.
What does each look like?
The aji limo is a small, tapered pod, two to three inches long, that ripens through yellow and orange to red (with a purple variety too). The lemon drop is similar in size but more wrinkled and crinkled, and it typically stays a vivid yellow when ripe — the color that helped earn its name. Side by side, the lemon drop’s bumpy yellow pods are usually the giveaway.
Which is easier to find?
Neither is a supermarket regular outside Peru, but the lemon drop has the edge for home growers. Its seeds are widely sold and it’s a popular, productive garden variety in North America and Europe. Fresh aji limo is harder to source outside Peruvian and specialty markets, though both turn up dried or as seeds online. For most cooks, the lemon drop is the easier of the two to actually get hold of.
Which is more useful in the kitchen?
Both are prized for the same reason — citrusy heat — but they have signature roles. The aji limo is inseparable from Peruvian seafood: it’s a defining chili in ceviche and tiradito, where its aromatic citrus lifts the leche de tigre. The lemon drop is a bit more of a generalist, bringing bright lemon heat to salsas, hot sauces, marinades, and dishes where you want citrus lift without a specific regional stamp. It also dries and powders beautifully, holding its lemony punch.
Overall: same citrus theme, different peppers
The aji limo and the aji limón/lemon drop are cousins in flavor, not twins in the pantry. Choose the aji limo when you want more heat and a rounder, more tropical-floral citrus, especially for authentic Peruvian ceviche. Choose the lemon drop when you want a gentler, cleaner, more purely lemon flavor, or when it’s simply the one you can find.
Because they share so much, they also sub for each other well: the lemon drop is a milder stand-in for the aji limo, and the aji limo a hotter stand-in for the lemon drop. See our aji limo substitutes guide for the full lineup.
