Handle Multi-Ingredient Products

As a Host, I want to map products that contain multiple ingredients (like pre-made sour mix), So that the system accurately tracks what’s in my inventory.

Acceptance Criteria

• Given I have a product like “Margarita Mix” that contains lime juice and simple syrup
• When I map this product to ingredients
• Then I can associate it with multiple generic ingredients:
  • Lime Juice (primary)
  • Simple Syrup (secondary)
• And I can specify the ratio or percentage of each ingredient
• And when calculating shopping lists, the system accounts for multi-ingredient products
• And I can mark certain products as “preferred” or “avoid” for specific ingredients

Implementation Status

✅ PARTIALLY IMPLEMENTED (December 2025)

Implementation Details

Current Implementation:

• Products can be mapped to multiple ingredients via ingredientIds array
• Multiple ingredients per product is supported

Missing Features:

• Ratio/percentage specification for each ingredient
• Primary/secondary ingredient designation
• Shopping list calculation for multi-ingredient products
• Preferred/avoid preferences for ingredients

Files:

• shaker/types/product.ts - Product type with ingredientIds: string[]
• shaker/app/(tabs)/inventory/products/edit-product.tsx - Multi-ingredient selection

Note: Basic multi-ingredient mapping exists, but advanced features (ratios, preferences) are not yet implemented.
