Aji amarillo is a staple in Peruvian cuisine, a chile pepper with a bright orange color and thick flesh. Its heat level ranges from medium to hot, and it is commonly used in a variety of soups and sauces. This chile variety is native to South America and has a distinctive, subtle, and full-bodied fruitiness.

It can be bought in a few forms: dried, fresh, canned, or in the form of a paste. When incorporated into sauces, it is often thickened with bread, mayonnaise, and dairy products, and it is then spooned over a variety of meat, fish, and vegetable dishes. 

Aji límo (also known as lemon drop pepper) is a Peruvian hot pepper with a citrusy tang and a Scoville heat unit of 15,000-30,000. When mature, its color becomes golden-yellow, and the flavor becomes fruity, with some people comparing it to fresh lemongrass.

This chili variety is ideal for spicy salsas, hot sauces, and dishes based on chicken or fish. In Peru, it is often used as a seasoning for various main meals and snacks.

Rocoto chile is a type of chili pepper that is believed to have originated in the Andean areas of Peru and Bolivia, where it has long been grown and used as an essential ingredient of traditional cuisine. It belongs to the Capsicum pubescens genus and is characterized by hairy leaves and dark seeds ranging from dark brown to black, while its rather thick and juicy flesh may be of red, orange, yellow, or green color.

Varying in both size and shape, the rocoto chili is renowned for being one of the hottest peppers in the world, and it is distinguished by a rich, fruity, and spicy flavor. Rocoto chilis may be enjoyed fresh as an accompaniment to various dishes, made into chili paste and used as a condiment, or ground to a powder-like consistency and used as a spice. 

Peruvian panca chili, or ají panca as it's known in South America, is the second most common pepper in Peru, grown all along the coast. This deep red to burgundy colored hot pepper is similar in appearance to ají amarillo, only less spicy and has a rather sweet, berry-like, and slightly smoky flavor with a pronounced floral bouquet.

Ají panca can be made into a paste or it can be dried and minced. It is widely used as a seasoning in Peruvian cuisine, especially for various sauces, stews, and fish-based dishes like the famous parihuela seafood soup.

Papa púrpura are Peruvian purple potatoes. The skin and flesh have a deep purple color, and when cooked, the potatoes usually turn bluish. They're cooked just like regular potatoes and the flavor is also similar to regular potatoes, just with buttery notes.

It's recommended to roast them, add them to salads, or deep-fry them. In pre-Hispanic times, purple potatoes were usually reserved exclusively for the Inca Kings, and nowadays some chefs affectionately call them Gems of the Andes. Interestingly, they contain two to three times the antioxidants found in yellow or white potatoes.

Ulluco is an economically important South American root crop that is indigenous to the Andean region in South America. It is widely cultivated and consumed in Peru, Bolivia, Ecuador, Colombia, Argentina, Venezuela, and Chile. Having its roots in ancient times, this root vegetable used to represent an essential food crop for the Incas, and it has long been grown primarily for its tubers, but also for its leaves, both of which are edible and equally flavorful.

Varying in both size and shape, the tubers may have a bright yellow, green, orange, red, pink, or purple exterior that surrounds white or yellow flesh. These tubers are characterized by a smooth, firm, and crispy texture with a distinctive and somewhat earthy flavor. 

One of the valuable food sources and medicinal plants of indigenous Andean populations, and native to the Andean region, mashua is a type of tuberous crop that continues to be grown in countries such as Peru and Bolivia (and to lesser extent in Ecuador), although mostly for household consumption.

There are both domesticated and wild mashua varieties, and the plant’s tubers vary in size and color, depending on the variety. Mashua tubers are shiny and cone-shaped and may come in white, pale yellow, orange, red, purple, or even black color. 

This South American perennial plant has long been grown for its edible roots. Yacón tubers resemble sweet potatoes and may come in various colors including white, pink, red, yellow, orange, or purple, while their flesh is typically white.

This root-like vegetable is characterized by a distinctive, mildly sweet flavor with hints of apples, pears, celery, and watermelon. It has a pleasant crispiness that the tubers retain even after they have been cooked. Yacón is highly-appreciated for being a fantastic source of moisture, electrolytes, salts, and starch, which is why the juice of its tubers used to be enjoyed as a potent refreshing beverage by the indigenous populations in the past, and is probably the reason for its name, which translates to water root in the Inca language. 

Maca is the ancient root vegetable, a variety of radish, native to areas of Peru. It is extremely resilient since it is able to thrive in the harsh environment of the Andes, and many believe that it has many beneficial properties, which promotes it as one of the most common ingredients used in medical remedies.

In gastronomy, it is regarded as superfood, and is mainly used in powder form to provide a higher nutritional value to standard dishes. As any other root vegetable, maca is commonly served boiled or roasted, and is often incorporated in nourishing stews and soups.
