# The Pantry Tetris Algorithm
**Subject Line:** The algorithm that stops you throwing food away

## Hook
You buy a bag of celery for Tuesday's stir-fry. By Friday, it's brown and slimy. Sound familiar?
What if your meal planner was smart enough to automatically suggest Thursday's soup — specifically because it uses the other half of that celery?
## The Insight
I've been building a "Zero-Waste Logistics Engine" for home cooking.
Here's how it works:
1. **Scrape the data** — We intercept product APIs from Lidl and Aldi (no OCR needed — they have hidden JSON endpoints)
2. **Track the pantry** — AI remembers what you bought and when
3. **Connect the recipes** — If this week's recipe uses half an ingredient, next week's automatically uses the rest
The result? Fewer brown bags of shame in your fridge.
## Why It Matters
- **For SaaS Founders:** This is churn prevention for groceries. The "stickiness" comes from accumulated pantry data.
- **For DTC Brands:** Subscription boxes could use this logic — ship what completes existing inventory, not random products.
- **For Content Creators:** Recipe content that adapts to what viewers actually have.
## The Deeper Model
This isn't just about cooking. It's about **interface discovery** — finding the hidden APIs behind any retail site. "Talk to the kitchen, not read the menu."
