Mockernut hickory is the most abundant of the hickories in some regions, and while its name suggests otherwise, its nuts are indeed edible. Though notoriously difficult to crack, the small kernel inside is a sweet reward for the determined forager. This guide covers everything you need to know about consuming this wild delicacy.

Quick Summary

Mockernut hickory nuts are edible and sweet, but their thick shell and small kernel make extraction difficult. Identification is key, focusing on bark, leaves, and fruit characteristics. Harvesting involves collecting ripened nuts, discarding floaters, and using specific techniques to crack the hard shell. The nuts can be used in various recipes.

Key Points

Edible but challenging: Mockernut hickory nuts are edible and sweet but notoriously difficult to crack due to their thick shell.
Identification is key: Identify the tree by its tight bark, 7-9 leaflets with hairy undersides, and a large, hairy terminal bud.
Harvest in autumn: Collect nuts in autumn after their husks naturally split and they fall from the tree.
Check for soundness: Use a float test to discard immature or spoiled nuts before drying and processing.
Valuable resource: Mockernuts are a nutritious wild food source, rich in fats and protein, and can be used in baking or roasted for snacks.
Worth the effort: The sweet, buttery flavor of the mockernut meat makes the difficult extraction process worthwhile for foragers.

Is Mockernut Hickory Edible?

Yes, the nuts of the mockernut hickory tree ($Carya tomentosa$) are edible for humans. In fact, they possess a delicious, sweet, and nutty flavor, sometimes described as richer than other hickory varieties. Despite their tasty reward, they are often overlooked as a food source due to the difficulty of extracting the meat from the nut's thick shell. The sweet kernel can be used in any recipe calling for pecans or walnuts, or simply enjoyed as a raw snack.

Why is it called "Mockernut"?

The tree's common name comes from its thick, hard shell, which 'mocks' the efforts of those trying to crack it open to get at the nutmeat. Unlike other hickories, the size of the kernel is disproportionately small compared to the large size of the shell and husk. The difficulty is why mockernut is a less popular commercial nut, though many foragers consider the flavor worth the effort. The name serves as a warning that the prize is not easily won.

Identification: A Forager's Guide

Proper identification is crucial when foraging. Here are the key characteristics of the mockernut hickory tree ($Carya tomentosa$):

Leaves: Leaves are alternate, pinnately compound, with 7 to 9 leaflets, though 7 is most common. The leaves are densely hairy or pubescent on the underside and along the leaf stem (rachis). The crushed leaves can have a spicy, orange-like scent.
Bark: Unlike the shaggy bark of its cousin, the shagbark hickory, mockernut bark is tight, gray, and has interlacing, rounded ridges that don't peel away easily.
Twigs and Buds: Twigs are stout and hairy. The terminal bud is distinctly large, egg-shaped, and covered in light-tan, silky hairs.
Fruit and Nut: The fruit is a thick-husked nut, 1.5 to 2 inches long, which ripens in the fall. The husk splits cleanly into four sections to reveal a hard, four-ribbed nut inside. The nut shell is thick and exceptionally hard.

Harvesting and Processing Mockernut Nuts

Harvesting these nuts requires patience and the right timing. The process generally follows these steps:

Timing the Harvest: The nuts are ready when their husks split open on the tree and they fall to the ground, usually in early to mid-autumn. Avoid nuts that fall prematurely, as they may be undeveloped or damaged.
Removing the Husk: After collecting, the thick, four-part husk can be easily peeled away from the nut inside.
Performing the Float Test: A float test is a reliable way to check for soundness. Place the husked nuts in a bucket of water. Any nuts that float should be discarded, as they are likely immature, hollow, or infested with weevils.
Drying the Nuts: After the float test, dry the nuts for at least a week by spreading them in a single layer in a warm, dry area with good airflow. This prevents mold and helps preserve the nutmeat.
Cracking the Shell: Due to the shell's thickness, a standard nutcracker is often insufficient. A hammer on a hard surface is a common method, focusing on creating an 'X' pattern to aid removal. For a more traditional approach, Native Americans would grind the nuts, shell and all, to make a nutritious nut milk.

Nutritional and Culinary Uses

Mockernut nuts are a nutrient-dense food source, rich in healthy fats, protein, and essential minerals. A 100g serving contains approximately 657 kcal, 64g of fat, and 12.7g of protein. The nuts are also a good source of vitamins B-6 and E, as well as minerals like potassium, magnesium, and phosphorus.

Culinary Uses:

Baking: Substitute mockernut meat for pecans or walnuts in pies, muffins, cookies, and breads.
Roasting: For a savory snack, brine and roast the shelled nut meats. This enhances their natural salty flavor.
Hickory Milk: For a unique and rich addition to soups or baked goods, use the traditional Indigenous method of boiling crushed nuts (shells included) to extract the oil and flavor.
Nut Butter: The high oil content makes them perfect for grinding into a rich, flavorful nut butter.

Mockernut vs. Other Hickory Nuts: A Comparison


Feature	Mockernut Hickory ($Carya tomentosa$)	Shagbark Hickory ($Carya ovata$)	Bitternut Hickory ($Carya cordiformis$)
Bark	Gray, tight with interlaced ridges; never shaggy.	Light gray, peeling off in long, shaggy strips.	Smooth gray bark on young trees, developing tight furrows on older ones.
Leaves	Usually 7 leaflets, densely hairy underneath.	Usually 5 leaflets, smooth or sparsely hairy.	Usually 7-9 leaflets, often smaller than mockernut.
Nut Taste	Sweet and nutty.	Sweet, buttery, considered one of the best.	Unpalatably bitter.
Shell Thickness	Very thick and hard.	Thick but easier to crack than mockernut.	Very thin and easy to crack.
Nut Meat Size	Relatively small.	Plentiful.	Small, bitter.

Conclusion

In summary, mockernut hickory nuts are a safe, sweet, and nutritious food source, but they demand patience and effort to extract. Unlike the inedible bitternut, mockernut nuts offer a rich reward for the determined forager. With careful identification and proper harvesting techniques, you can enjoy this wild delicacy in a variety of culinary applications. The challenge of the thick shell is part of the tradition and the ultimate satisfaction of enjoying a true wild food.

Frequently Asked Questions

Due to their thick shell, standard nutcrackers are often ineffective. A common method is to place the nut on a flat, hard surface and tap it lightly with a hammer, aiming to create an 'X' pattern of cracks to aid removal of the nutmeat.

Yes, once you successfully extract the nutmeat, it is safe and delicious to eat raw. You can also roast them to enhance their flavor.

Mockernut hickory has tight, interlaced bark that doesn't peel, and its leaves are densely hairy underneath. Shagbark hickory is known for its distinctive shaggy bark that peels in strips, and its leaves are typically smoother.

Mockernut nuts have a sweet, nutty flavor that is sometimes described as richer than pecans. Some foragers find the flavor comparable to, if not better than, pecans, making them worth the extra effort to shell.

In addition to the edible nuts, the wood is highly prized for its strength and is used for tool handles, furniture, and smoking meats. Native Americans also used the crushed nuts and bark for various purposes.

After harvesting, testing, and drying the nuts, you can store them in their shell in a cool, dry place for a few months. For longer-term storage, shell the nut meats and freeze them.

While all hickory nuts are technically safe to eat, some species, like the bitternut hickory, are unpalatably bitter. Mockernut, shagbark, and pecan nuts are all known for their sweet flavor.
