# Recipe Ingredient Scaler

Rescale any recipe's ingredient list to a new serving count, converting cups/tbsp/tsp ⇄ grams/ml with per-ingredient densities and kitchen-friendly fraction output.

## Overview

Paste ingredient lines in any common format — “2 1/4 cups all-purpose flour”, “1½ tsp salt”, “3 large eggs”, “200g/7oz chocolate”, ranges like “1-2 cups spinach” — the parser handles mixed numbers, unicode fractions (½ ⅓ ⅔ ¼ ¾ ⅛), unit synonyms (T/t/tbsp/c/fl oz/#/gr), container words (clove/can/slice), parenthetical notes and “to taste” markers. Scaling is exact internally; rendering snaps to kitchen grids (tsp to ⅛, tbsp to ½, cups to ¼/⅓) and demotes awkward fractions to smaller units (0.375 cup → 6 tbsp, 7½ tsp → 2 tbsp 1½ tsp), prefixing “~” when rounding drifts past 5%. Unit conversion uses exact US customary factors (cup = 236.6 ml) plus a 70-entry density table (flour 120 g/cup, packed brown sugar 220 g, butter 227 g = 2 sticks, honey 340 g…) cross-verified between King Arthur Baking and USDA; unknown ingredients keep their volume unit and still scale. Smart seasoning mode scales salt/spices/extracts by factor^0.85 beyond 2× (the professional consensus that you “season 1.5× when doubling”) while showing the linear value. Counts scale with fractions (1½ eggs ≈ 75 g). Cooking times and temperatures never scale.

## Inputs

- **Recipe ingredients (one per line)** (textarea): 2 1/4 cups all-purpose flour 1 tsp baking soda 1 cup butter, softened 2 large eggs
- **Original servings** (number)
- **Target servings** (number)
- **Output units** (select)
- **Smart seasoning scaling** (checkbox)

## When to use

- Doubling, tripling, or halving a recipe to fit specific pan sizes or guest counts.
- Converting US volume recipe measurements like cups and tablespoons into grams and milliliters for baking.
- Adjusting large-batch recipes without over-salting or over-spicing through smart seasoning scaling.

## How it works

- Paste your raw ingredient list including quantities, fractions, unit names, and item notes.
- Set the original serving count, target serving count, and desired output units (Keep original, Metric, or US volume).
- The tool parses mixed numbers and ranges, queries a verified 70-entry ingredient density table for mass conversions, and calculates scaled quantities.
- View clean, kitchen-friendly outputs formatted with standard fractional grids and sub-linear seasoning recommendations.

## Use cases

- Bakers converting cup-based American pastry recipes into precise gram measurements for kitchen scales.
- Home cooks halving family-sized stew and soup recipes down to 1 or 2 individual portions.
- Caterers and meal preppers scaling up standard 4-serving dinner recipes to 24 or 48 servings.

## Frequently asked questions

### How does the tool convert volume (cups) into weight (grams)?

It matches ingredients against a verified 70-entry density database cross-referenced with USDA and King Arthur Baking standards, applying specific gram weights per cup for items like flour, sugar, and butter.

### What is smart seasoning scaling?

When scaling up by 2× or more, smart seasoning applies a sub-linear curve (factor^0.85) to salt, spices, and extracts to prevent over-seasoning, while still displaying the direct mathematical value.

### How are awkward decimal values displayed?

Values snap to standard kitchen fractions (such as ⅛ tsp, ½ tbsp, ¼ cup) or demote into easier units, such as turning 0.375 cups into 6 tablespoons.

### Does this tool scale cooking times or temperatures?

No. Cooking durations, oven temperatures, and non-quantitative instructions are never scaled, as thermal physics and pan dynamics do not scale linearly with batch size.

### Can it process ingredient lines with notes and 'to taste' items?

Yes. The parser recognizes parenthetical prep notes, container descriptors (cloves, cans, slices), and preserves 'to taste' labels without breaking calculations.
