PantryMatch

PantryMatch answers one question fast: out of a fixed catalog of 50 recipes, which ones can you actually cook right now with what's already in your kitchen? Check off which of 80 common pantry ingredients you currently own, and PantryMatch instantly ranks every recipe from "Ready Now" down to "missing N ingredients" — no typing, no photos, just tapping a checklist. The matching is substitution-aware, not a naive checklist. Seven built-in substitution groups (like butter/olive oil/vegetable oil, or milk/cream/yogurt/sour cream) mean owning any one member of a group satisfies a recipe that calls for another — so you're never told a recipe is "missing butter" when you actually have olive oil that would do the job. Recipe Detail clearly separates owned, owned-via-substitute, and genuinely missing ingredients. The real centerpiece is the Smart Shopping List. Instead of just listing every missing ingredient across every recipe, it runs a greedy maximum-coverage optimization: given a budget of how many items you're willing to buy, it works out which specific ingredients to buy next to unlock the most additional ready-to-cook recipes — genuinely optimizing for recipes unlocked, not just picking whatever ingredient appears in the most recipes. A Stats screen tracks your pantry fill level and ready-recipe count over time, with a weekly trend chart, a category breakdown of what you own, and a "closest miss" callout for the recipe nearest to being ready. PantryMatch is a matching and optimization tool, not a cookbook: it does not include step-by-step cooking instructions for its recipes. It also has no barcode or receipt scanning and no connection to any external recipe database — the 80 ingredients and 50 recipes are a fixed, built-in catalog, and the entire app works fully offline with no account and no internet connection required. Key features: • 80-ingredient pantry checklist across 9 categories, organized with a category sidebar • 50 built-in recipes ranked by readiness — Ready Now first, then by how many ingredients are missing • Substitution-aware matching across 7 real kitchen substitution groups (fats, dairy, acids, cheeses, alliums, sweeteners, legumes) • Smart Shopping List — a greedy optimization that picks which few ingredients to buy next to unlock the most new ready-to-cook recipes • Stats screen: ready-recipe trend, pantry category breakdown, activity heatmap, and a "closest miss" callout • Fully offline, no account, no barcode/receipt scanning, no external recipe database
