Andean Cau Cau: Cumin-Roasted Corn & Potato Fritters
These rustic Andean fritters replace the traditional deep-fry method with a high-heat roast in extra-virgin olive oil, locking in the earthy sweetness of heirloom corn and starchy potatoes. Dusting them with toasted cumin and fresh huacatay (black mint) delivers a vibrant, aromatic profile that honors the mountain tradition while eliminating inflammatory seed oils.
A little context
Originating from the high Andes, Cau Cau is traditionally a street-food staple of fried corn and potato balls, often served alongside grilled meats. We honor this heritage by keeping the core ingredients—choclo (giant corn) and papa (potato)—intact but swap the industrial seed oils for cold-pressed avocado oil or EVOO to reduce oxidative stress. The sweetener often found in modern variations is omitted entirely, relying on the natural caramelization of the vegetables and the earthy spice profile for depth.
The longevity story
This dish leverages the resistant starch formed when potatoes are cooked and cooled slightly, which acts as a prebiotic to support gut microbiome diversity. The extra-virgin olive oil provides robust polyphenols like oleocanthal, offering potent anti-inflammatory effects, while the cumin and huacatay add antioxidant density without added sugars. By using organic, non-GMO heirloom corn, we maximize the intake of lutein and zeaxanthin, crucial for eye health and cellular protection.
Method
- 01
Preheat and Prep
Preheat your oven to 200°C (400°F). Line a large baking sheet with a silicone mat or a light coating of avocado oil spray. Place the diced potatoes in a pot of cold, salted water, bring to a boil, and par-cook for 5 minutes until just tender but not falling apart. Drain thoroughly and let steam dry for 5 minutes.
- 02
Process the Base
In a food processor, pulse the par-cooked potatoes and fresh corn kernels until they form a coarse, sticky mixture. Do not over-process into a puree; you want visible texture. Transfer the mixture to a large bowl.
- 03
Combine and Bind
Add the almond flour, beaten eggs, chopped huacatay (or cilantro), toasted cumin, and sea salt to the vegetable mixture. Mix vigorously with a sturdy spoon or your hands until the mixture holds together when pinched. If it feels too wet, add 1 tablespoon more almond flour.
- 04
Form the Fritters
Wet your hands slightly to prevent sticking. Scoop about 2 tablespoons of the mixture and roll into a ball, then gently flatten into a 1.5 cm (1/2 inch) thick patty. Arrange them on the prepared baking sheet, leaving 2 cm (3/4 inch) between each.
- 05
Oil and Season
Brush the tops of the fritters generously with the extra-virgin olive oil and sprinkle a tiny pinch of flaky sea salt on top. This ensures a golden, polyphenol-rich crust.
- 06
Roast to Crisp
Bake for 20 minutes, then carefully flip each fritter. Brush the second side lightly with a little more olive oil if the pan looks dry. Return to the oven for another 15–20 minutes until the edges are deep golden brown and crisp.
- 07
Finish and Serve
Remove from the oven and let rest for 5 minutes to set. Dust with an additional light sprinkle of cumin and serve immediately while hot and crisp.
Pro tips
- ✦Source 'choclo' (giant Andean corn) at Latin American markets; its large, starchy kernels provide the authentic texture and sweetness that standard sweet corn lacks.
- ✦Do not skip the par-boiling of the potatoes; raw potatoes will not bind correctly and will remain gritty in the center.
- ✦Toast your cumin seeds in a dry pan until fragrant before grinding; this releases volatile oils that are lost in pre-ground spices.
- ✦If the mixture is too sticky to handle, chill it in the fridge for 15 minutes before forming patties.
- ✦Look for huacatay (black mint) in specialty stores; its unique anise-citrus flavor is the soul of the dish, but fresh cilantro is a valid, accessible substitute.

Substitutions
- almond flour → coconut flour (use 1/3 the amount) (coconut flour is highly absorbent; add 1 extra egg if using this swap to maintain moisture.)
- huacatay (black mint) → fresh cilantro + a drop of lime zest (mimics the citrusy, herbal notes of the traditional herb.)
- Yukon Gold potatoes → organic fingerling potatoes (use a mix of yellow and purple fingerlings for extra anthocyanin polyphenols.)
Storage
Cool completely and store in an airtight glass container in the fridge for up to 4 days. Reheat in a toaster oven or air fryer to restore crispness; do not microwave. Freezes well for up to 3 months; bake from frozen at 190°C (375°F) for 15 minutes.
What to serve with it
- Serve with a side of fermented red cabbage slaw for a gut-health boost.
- Pair with a glass of unsweetened hibiscus tea or sparkling water with fresh lime.
- Complement with grilled wild-caught trout or pasture-raised chicken breast.
- A small glass of dry Pinot Noir fits the polyphenol profile if alcohol is desired.
FAQ
Can I use canned corn?+
Canned corn often contains added sodium and preservatives. Fresh or frozen organic corn is preferred to maintain the low-sodium, whole-food integrity of the recipe. If you must use canned, rinse it thoroughly under cold water.
Why not deep fry these?+
Traditional Cau Cau is deep-fried, which can degrade healthy fats and create oxidation products. Roasting in high-quality EVOO or avocado oil achieves a similar crisp texture while preserving the anti-inflammatory properties of the fat.
Are these gluten-free?+
Yes, provided you use certified gluten-free almond flour and ensure your baking powder (if added later) is gluten-free. The recipe naturally avoids wheat, barley, and rye.
