Recipe Scaler nonlinear scaling rules

recipe-scaler-nonlinear-rules

Rule
salt
scales Linearly
No
title
Salt does not always scale 1:1
rule
For fermenting and brining, salt is a percentage of the total weight of the other ingredients - not a multiple of servings. Doubling a sauerkraut recipe and doubling the salt by volume can push the batch outside the safe 2% lacto-fermentation line. For table cooking, salt usually scales with servings, but volume measures vary wildly between brands (Morton vs Diamond Crystal kosher salt differ by ~40%).
failure
A doubled sauerkraut batch made with doubled table-salt spoons can climb past 3.5% salt, stalling fermentation or leaving the batch unsafe; a halved batch with the same 1 tsp can fall below 2% and let molds win.
source hint
USDA home-canning 2% brine fact
spice
scales Linearly
No
title
Spices and heat do not scale linearly
rule
Chili heat, clove, and cinnamon concentration follow their own curve. Doubling a recipe does not mean doubling cayenne or cloves - volatile oils and capsaicin compound faster than volume. Scale pungent spices by about 50% of the factor for large jumps, then taste.
failure
Doubling a chili recipe with 2x cayenne can turn a family dinner into an inedible fire-breather; doubling cloves can make a cake taste like perfume.
source hint
Common baking/spice reference (fom-tool-logic)
yeast
scales Linearly
No
title
Yeast should not be doubled with the batch
rule
When you double a yeasted dough, use about 1.5x the yeast, not 2x. Yeast growth is exponential, not linear - the same cells reproduce to fill the larger dough. Common baking rule of thumb: doubling the recipe means about 1.5x yeast; tripling means about 2x yeast.
failure
Doubling yeast with a doubled batch produces an over-proofed, yeasty, collapsing loaf - the dough over-ferments before shaping.
source hint
Red Star yeast conversion reference
fermentation time
scales Linearly
No
title
Fermentation time does not scale with batch size
rule
A bigger batch of dough, sauerkraut, or brine ferments at roughly the same rate as a small one - the microbes work per-cell, not per-volume. Temperature, not batch size, is the lever. Do not multiply fermentation or proofing time by the scaling factor.
failure
Doubling a sourdough recipe and doubling the proof time over-ferments the dough - flat, sour, collapsed bread.
source hint
Sourdough bulk fermentation guide + lacto-ferment temp range
oven time
scales Linearly
No
title
Oven time does not scale with servings
rule
Bake time tracks pan geometry and batter depth, not servings. Doubling a cake into two identical pans bakes in roughly the same time; doubling into one larger pan means deeper batter and a longer bake - but not double. Check doneness with a thermometer (cakes about 200-210F), not the clock.
failure
Scaling a 9x13 cake to 2x and keeping the same bake time under-bakes the center; adding 2x the time over-bakes the edges into a hockey puck.

Gas range energy transfer efficiency

cooking-method-efficiency-gas

Fact
32–40%
Applies to Gas ranges transfer only 32-40% of the gas energy to the food. Most energy is lost to ambient air heating, incomplete combustion, and heat traveling up the sides of the pan. This is the lowest efficiency of common cooking methods.

Cost Per Use / Total Cost of Ownership formula

cpu-tco-formula

Fact
formula
TCO over hold = sum of purchase cycles (price + maintenance + repair) - residual
cost per use
Cost per use = TCO over hold / (weekly uses x 52 x hold years)
note
Compare decisions, not products: cheap tier vs better tier on annualized cost, driven by real price/lifespan/repair data - not usage frequency.

Provenance rebuild 2026-09-11 (card t_407759be) per Ethan's report 2026-09-11-cpu-lifespan-threshold-authoritative-sources-Ethan.md. source_ids here is the UNION of each category's own source_ids (attribution is per category, not rule-wide): the ENERGY STAR programme was dropped because its product catalogue does not cover home blenders, rice cookers or coffee grinders, let alone cookware, food containers or garden tools (report section 5, C-1), and the internal derived-math source was dropped too because no value in this rule is mathematically derived (its only legitimate home is cpu-tco-formula). Per-tier evidence fields: lifespan_evidence is one of warranty-minimum | warranty-backed | manufacturer-published | manufacturer-survey | estimate | unsourced, always paired with lifespan_basis naming the source; maintenance_basis and repair_basis are mandatory and say 'unsourced' when no published price or interval exists, so a 0 can never masquerade as 'free' (M-3). maintenance_per_year is null wherever no sourced annual figure exists. repair_per_event is null where no public price exists - null means NOT IN TCO, never $0 (H-1). residual_pct is 0 on all 12 tiers: FOM does not assume resale value, and no tier has a sourced second-hand price (H-2 option a). Range handling across the whole table: when a source publishes only a range, the engine point value is the end that matches the tier (budget tier -> lower end, premium tier -> upper end); a midpoint is never used (rows 6/13/14).

buy cheap
The budget option's total lifetime cost is lower for what you need — spend less.
buy better
The premium's lower total cost of ownership pays for its higher price — durability, repairability, or running costs, not usage frequency.
buy once
Its useful life is long enough that repeated cheap replacements cost more — buy one good one and keep it.
don't buy
You won't use it enough to justify any ownership cost — borrow, repair, or skip.

These four thresholds (0.5 uses/week, 3 years, 8 years, +15% repairable surplus) are editorial stance, not facts - no external source exists for them and none can (report section 5, H-3). evidence_class rides inside value so downstream prose can say 'our threshold' instead of 'research shows'. The internal derived-math source id was dropped: it may only be cited where a value is genuinely derived by math (cpu-tco-formula), and these thresholds are not. fom-tool-logic is kept only to record where the numbers actually live - our own tool logic.

A source is listed against the records it actually supports. Where one source backs records across several topics, each record links back here separately — a source is never presented as the single origin of knowledge it does not cover.

Generated at build time from toolFacts.json, toolRules.json and toolSources.json. Article links are derived by scanning each guide for the data it actually references — they are not maintained by hand.
