Sanctuary for Heirloom Biodiversity

Heirloom beans are living cultural artifacts. For thousands of years, indigenous farmers and heritage growers preserved landraces with astonishing colors, rich pot liquors, and distinct culinary personalities. Frijolio puts this botanical knowledge into your pocket with precision culinary timing and AI taxonomy.

The Five Pillars of Frijolio

🗺️

Frijolevision Atlas

Trace 50+ global landraces across 5 continents. Explore botanical morphology, origin maps, broth textures, and flavor radar profiles.

🔥

The Bean Sommelier

Dynamic cook-time calculator accounting for vessel type (Clay Pot, Dutch Oven, Instant Pot), soak method, and high-altitude atmospheric pressure.

📸

AI Botanical Scanner

Computer vision for bulk bins and seed jars. Identify dried bean varieties on-device with live iNaturalist botanical cross-referencing.

🏺

Pantry Vault

Track your personal pantry inventory with harvest years, purveyor sources, weights, and gentle reminders for aging vintage stock.

🌐

World Share & Passports

Export portable .json bean passports. Submit corrections and propose new heirloom varieties directly to the GitHub repository.

🌱

Heirloom Sourcing

Direct sourcing guides to ethical heirloom purveyors including Rancho Gordo, Zursun, Camellia, and independent seed keepers.

Developer Diary & Agronomy Notes

The journey of building a specialized culinary and botanical companion from scratch.

Phase 1: The Spark

The Lost Varieties of the Kitchen

Standard grocery aisles reduced thousands of bean varieties to three generic commodity bins: black, pinto, and navy. When we first cooked an artisanal batch of fresh heirloom Ayocote Morado in an unglazed earthenware pot, the difference in broth viscosity, creamy interior texture, and complex savory notes was an epiphany. We started cataloging every landrace we could find.

Phase 2: Culinary Physics

Altitude, Clay & Starch Gelatinization

Why do bean cooking times vary from 45 minutes to 3 hours? We mapped the food science variables: starch gelatinization rates, pectin cross-linking with calcium ions in hard water, acid inhibition, and water boiling point depression at altitude. The Bean Sommelier was born to calculate precision cooking windows so cooks never end up with cracked skins or chalky centers.

Phase 3: The Vision Matrix

On-Device Morphology & iNaturalist

Dried heirloom beans exhibit distinctive signatures: hilum eye shapes, speckled marbling, aspect ratios, and seed coat striations. Using on-device CoreML vision coupled with real-time open taxonomy from iNaturalist, Frijolio turns your iPhone into a field guide for farmers markets, seed swaps, and spice bazaars.

Phase 4: Open Community

Decentralized Passports & GitHub Sync

Preserving biodiversity requires open collaboration. Instead of locking your records inside a closed database, every bean in Frijolio can be exported as a flat .json passport. Users can propose corrections or submit regional landraces straight to our open-source GitHub repository.
