Cacahuate
Cacahuate is the Spanish word for peanut, used mainly in Mexico (maní is more common in Central America, the Caribbean, and South America). Botanically a legume rather than a tree nut, cacahuate grows underground in a papery shell and is eaten roasted, salted, boiled, or ground into salsas, moles, and candies throughout Mexican cooking.
Varieties
Cacahuates japoneses are peanuts coated in a crunchy wheat-flour-and-soy shell, a distinct snack format from plain roasted cacahuates and not interchangeable in cooking since the coating burns easily if used in sauces. Raw cacahuates are also sold specifically for boiling into cacahuates hervidos, a soft, salted preparation different from the roasted kind.
Buying tips
For in-shell cacahuates, shake the bag: shells should feel full with minimal rattling, since rattling means the nut has shrunk or dried out. For shelled peanuts, look for uniform tan color without dark spots or a shriveled appearance, which can signal age or improper storage.
Substitutes
Almonds, chopped or slivered — 1:1
Milder and less sweet than peanuts; works in salsas and garnishes but changes the flavor of anything peanut-forward like mole or peanut sauce.
Cashews — 1:1
Closest in creaminess and fat content when ground into sauces or moles; slightly sweeter and less earthy than peanuts.
Pepitas (hulled pumpkin seeds) — 1:1
Common nut-free swap in Mexican cooking since pepitas are already a base for pipián sauces; toast first to match the roasted flavor of cacahuates.
Sunflower seeds — 1:1
Best all-purpose nut-free substitute for snacking or garnish; has a grassier flavor and lacks the fat richness peanuts bring to sauces.
Peanut butter (for ground/paste uses) — 2 tablespoons per 1/4 cup whole cacahuates
Use when a recipe calls for ground peanuts in a sauce or dressing and only peanut butter is on hand; reduce added oil in the recipe since peanut butter is already fatty.
Storage
Store raw or roasted cacahuates in their shells in a cool, dry pantry for up to a month. Shelled peanuts, especially raw ones, go rancid faster because their oils are exposed; keep them in an airtight container in the refrigerator for up to 3 months or the freezer for up to a year. Rancid peanuts smell faintly like paint or old crayons and should be discarded.
How to use
Eaten straight as a roasted, salted snack (cacahuates japoneses, coated in a crunchy soy-flavored shell, are a popular Mexican variety), tossed into elote and esquites, ground into salsa macha and some mole sauces for body and richness, candied with piloncillo for garapiñados, and used whole in dishes like picadillo or as a garnish on tostadas.
What it pairs with
Pairs well with chile de árbol and garlic in salsa macha, with lime and tajín as a snack, with piloncillo and cinnamon in candied preparations, and with chocolate and dried chiles in mole.
Nutrition
Cacahuates are high in protein and monounsaturated fat for a plant food, with roughly 7 grams of protein and 14 grams of fat per ounce. They're also a good source of niacin, folate, and magnesium, though salted roasted versions add significant sodium.
FAQ
Is cacahuate the same as maní?
Yes, both words mean peanut in Spanish. Cacahuate is used mostly in Mexico, while maní is standard in the Caribbean, Central America, and most of South America.
Is a cacahuate a nut or a legume?
Botanically it's a legume, related to beans and lentils, since it grows underground in a pod rather than on a tree. Nutritionally and in cooking it's treated like a nut.
Can raw cacahuates be eaten without cooking?
They're edible raw but starchy and hard to digest well; most recipes call for roasting or boiling them first to soften texture and develop flavor.
Why do some Mexican recipes use cacahuates instead of almonds in mole?
Peanuts are cheaper and more widely available in central and southern Mexico, and their higher fat content helps thicken and enrich the sauce without needing as much added oil.
