Tier 7 Implementation - Ingredient & Product Mapping

Tier 7: Ingredient Abstraction & Product Mapping

Status: ✅ COMPLETE Completion Date: January 2026 Related Story: Ingredient and Product Management

Overview

This implementation provides a complete ingredient abstraction and product mapping system that enables:

Generic ingredient definitions with flavor profiles
Smart product-to-ingredient mapping with auto-suggestions
Intelligent substitution recommendations
Flavor profile editing and comparison

Implementation Summary

Phase 1: Ingredient CRUD Screens ✅

1.1 FlavorProfileEditor Component

File: shaker/components/FlavorProfileEditor.tsx

A reusable component for editing 8-characteristic flavor profiles:

Sweet, Sour, Bitter, Salty, Umami, Spicy, Herbal, Fruity
Two variants: full (detailed) and compact (2-column layout)
Slider-based editing with real-time updates
Visual feedback with color-coded values

Usage:

<FlavorProfileEditor
  profile={ingredient.flavorProfile}
  onChange={(newProfile) => setIngredient({ ...ingredient, flavorProfile: newProfile })}
  variant="full"
/>

1.2 Add Ingredient Screen

File: shaker/app/(tabs)/inventory/ingredients/add-ingredient.tsx

Complete form for creating new ingredients:

Name, type, category, description
Flavor profile editor integration
Image URL input
Substitute ingredient selection
Form validation and error handling
GraphQL mutation preparation

Form Library: shaker/lib/ingredients/add-ingredient/

formTypes.ts - TypeScript type definitions
formFields.ts - Field configurations and options
formValidation.ts - Validation logic
index.ts - Module exports

1.3 Edit Ingredient Screen

File: shaker/app/(tabs)/inventory/ingredients/edit-ingredient.tsx

Loads existing ingredient data and allows editing:

Reuses add-ingredient form logic
Pre-populates form with existing data
Update mutation instead of create

1.4 Ingredient Detail Screen (Enhanced)

File: shaker/app/(tabs)/inventory/ingredients/[id].tsx

Enhancements:

Added “Edit” button to navigate to edit screen
Integrated IngredientSubstitutionSuggestions component
Shows intelligent substitution suggestions based on flavor profiles

1.5 Ingredients List Screen (Enhanced)

File: shaker/app/(tabs)/inventory/ingredients/index.tsx

Enhancements:

Added “Add New Ingredient” button in header
Navigation to add-ingredient screen

Phase 2: Product-Ingredient Mapping UI ✅

2.1 Products by Ingredient View

Implementation: Already exists in ingredient detail screen

Shows all products mapped to an ingredient
Displays product cards with navigation
Empty state when no products mapped

2.2 Product Detail Enhancement

File: shaker/app/(tabs)/inventory/products/[id].tsx

New Feature: Ingredient Mapping Card

Shows which ingredient(s) a product maps to
Displays ingredient name, type, category
Shows flavor profile chart
Clickable to navigate to ingredient detail
Only visible when product has ingredient mapping

2.3 Auto-Suggest Ingredient Mapping

Files:

shaker/utils/ingredientMapping.ts - Suggestion algorithm
shaker/components/IngredientMappingSuggestions.tsx - UI component

Algorithm Features:

Product type to ingredient type mapping
Name pattern matching (vodka, gin, rum, etc.)
Brand recognition
Category similarity
Confidence scoring (0-100%)
Reason explanations

Matching Criteria:

Product type matches ingredient type (+30 points)
Exact name match (+40 points)
Pattern matches (+30 points)
Category match (+20 points)
Similar category (+10 points)

Integration: Added to shaker/app/(tabs)/inventory/add-product.tsx

Auto-suggests when product name and type are entered
Displays top 3 suggestions with confidence scores
One-click selection to map product to ingredient
Hides when ingredient already selected

Phase 3: Smart Substitution System ✅

3.1 Ingredient Substitution Algorithm

File: shaker/utils/ingredientSubstitutions.ts

Function: findIngredientSubstitutes()

Matching Logic:

Explicit Substitutes (100 points) - Defined in ingredient data
Same Type & Category (80 points) - Exact match
Same Type (60 points) - Type match only
Flavor Profile Similarity (up to 40 points) - Cosine similarity
Product Availability (bonus 10 points) - Has mapped products

Flavor Similarity Calculation:

// Cosine similarity between two 8-dimensional flavor vectors
similarity = dotProduct / (magnitude1 * magnitude2)
score = similarity * 40  // Scale to 0-40 points

3.2 IngredientSubstitutionSuggestions Component

File: shaker/components/IngredientSubstitutionSuggestions.tsx

Features:

Match score badges (color-coded: green >= 80%, yellow >= 60%, gray < 60%)
Match reason explanations
Available products count
Clickable navigation to substitute ingredient
Optional flavor comparison charts
Responsive card layout

Next Steps

Immediate (High Priority)

Write Tests - Unit, component, and E2E tests for new features
GraphQL Integration - Connect mutations to backend when ready
Default Flavor Profiles - Create database of common ingredient flavor profiles

Short-term (Medium Priority)

Recipe Integration - Use ingredient mappings in recipe screens
Recipe Flavor Calculation - Aggregate ingredient flavors to show recipe flavor profile
Batch Ingredient Import - CSV import for bulk ingredient creation

Long-term (Low Priority)

Machine Learning - Improve auto-suggest with ML-based pattern recognition
Flavor Profile Templates - Pre-defined flavor profiles for common ingredient types
Community Flavor Profiles - Share and import flavor profiles from other users

Known Limitations

Mock Data Only - Currently using local mock data, not persisted to backend
No Flavor Profile Database - Default flavor profiles need to be manually created
Limited Pattern Matching - Auto-suggest patterns are hardcoded, could be more comprehensive
No Multi-Ingredient Products - Products can only map to one ingredient (future enhancement)

Performance Considerations

Auto-suggest Calculation - Runs on every form field change, memoized with useMemo
Substitution Algorithm - O(n) complexity where n = number of ingredients
Flavor Similarity - Cosine similarity is computationally efficient
Component Rendering - All components use React best practices (memoization, key props)

Accessibility

✅ All interactive elements are keyboard accessible
✅ Proper ARIA labels on form inputs
✅ Color-coded badges have text labels
✅ Touch targets meet minimum size requirements
✅ Error messages are clearly visible

Documentation

✅ Inline code comments for complex logic
✅ JSDoc comments on utility functions
✅ Component prop documentation
✅ Usage examples in component files
✅ This implementation summary

Conclusion

Tier 7 implementation is complete and ready for testing. The system provides a solid foundation for:

Recipe flexibility through ingredient abstraction
Smart product management with auto-suggestions
Intelligent substitutions based on flavor profiles
Future enhancements like recipe flavor analysis and menu balancing
