Which cactus is to eat?

Cacti are a type of succulent plant that are found primarily in arid regions of the Americas. There are over 2,000 different species of cactus that come in a wide variety of shapes, sizes, and colors. While most people are familiar with iconic cacti such as saguaro and prickly pear, not everyone realizes that many cactus fruits, pads, and even stems can be eaten. In fact, certain cactus parts have provided vital sources of nutrients and hydration for indigenous peoples across desert environments for thousands of years.

In recent decades, edible cacti have also gained popularity in mainstream cooking. The rich flavors and unique textures of cactus add delightful character when incorporated thoughtfully into recipes. However, it is important to have a good understanding of the different edible cactus types and how to properly handle and prepare them before eating. Some cacti can also cause adverse reactions if consumed incorrectly or in excess.

This article outlines key details and culinary guidance about the most common, safest, and tastiest cacti that can be eaten. Read on to learn which cacti you should eat, which parts to use, and tips for foraging, prepping, cooking, and serving different edible cactus varieties.

Overview of Edible Cactus Types

Many different cactus species produce edible fruits and pads. However, the most common types of cacti consumed include:

Prickly Pear – The fruit and pads of prickly pear cacti are edible. There are over 200 species found across the Americas. Their pulp can be eaten raw or cooked and made into jams, drinks, candies. The spines must be removed before consumption.

Nopales – Nopales refers to the edible, tender pads (leaves) of the Opuntia cactus, which includes prickly pear. They are often cooked and eaten as a vegetable in Mexican cuisine. The spines must be carefully removed before eating.

Dragon Fruit – The fruits of certain cacti in the Hylocereus genus are known as dragon fruit or pitaya. They have leathery, bright pink or yellow skin with white or red sweet, seed-speckled pulp inside.

Peyote – The edible button-like stem tops of peyote cactus contain the psychoactive alkaloid mescaline. They have historically been used in spiritual ceremonies but are illegal in many countries.

Saguaro – The tart red fruits and edible white inner pulp of giant saguaro cacti can be made into syrups and jams.

Key Considerations for Foraging and Preparing Edible Cacti

When seeking out wild cacti to eat, it is essential to correctly identify the species as safe and non-toxic. Always exercise caution and care when handling live cacti to avoid injuries from spines, glochids, and irritating sap. Safe processing techniques should also be used to remove any dangerous parts and make the edible portions ready to eat or cook. Here are some key tips:

– Wear thick gloves when handling and use tongs to avoid spines.

– Carefully singe off spines over an open flame before peeling.

– Cut off and discard outer skin to get to the inner pulp.

– Remove any spines, hairs, and glochids from fruit or pads.

– Slice off and discard the core and seeds from fruit.

– Boil nopales pads or simmer prickly pear fruits to decrease slime before eating.

– Avoid consuming high amounts as the sap contains oxalic acid.

Safe Preparation of Peyote Cactus

While peyote contains the controlled substance mescaline and is illegal in many places, certain indigenous groups are permitted to use it ceremonially. If legally and properly consumed, peyote requires extremely careful preparation to avoid illness:

– Remove brown exterior skin and cut off top buttons only.

– Avoid barrel-shaped peyote bases as these contain highly concentrated and toxic alkaloids.

– Dry tops whole under shade until hard or pound into small sun-dried discs. Never consume raw or insufficiently dried peyote.

– Soak dried tops or discs fully in water overnight then simmer for at least 12 hours, replacing water 2-3 times. Insufficient boiling can cause vomiting.

– Strain and drink the boiled peyote tea. Volume consumed should be carefully controlled.

– Effects take about 1-2 hours to manifest and can last up to 12 hours. Hallucinations, euphoria, nausea, increased body temperature, chills, and sweating can occur.

– Peyote use causes dilation of blood vessels. It should always be avoided by those with cardiovascular conditions or taking antidepressants.

Cooking with Saguaro Cactus Fruit

The ruby red pulp of saguaro cactus fruits offers a tart, tropical flavor when made into syrups, drinks, and preserves:

– Halve or quarter fruits, removing seeds, to process.

– Simmer pulp over low heat with added sugar and lime juice to taste until thickened. Strain out solids.

– Use saguaro syrup as a topping for desserts, mixed into drinks, or swirled into yogurt or oatmeal.

– Cook pulp down into a thick jam consistency for use in pastries like pop tarts and danishes.

– Can, pickle, or dehydrate pieces of prepared pulp for longer storage.

– Infuse pulp in simple syrup with rum or tequila for use in cocktails.

– Blend strained juice with citrus and cane sugar into agua fresca drinks.

– Freeze sweetened pulp into popsicles, sorbets, or ice cream.
