Here's your guide for substituting' (2021-01-21) anchors the per-egg ratios used: aquafaba 1/4 cup (57 g) per egg, 2 tablespoons per white, 1 tablespoon per yolk, with 1/8 teaspoon cream of tartar per 2 tablespoons when whipping; flax or chia egg = 1 tablespoon ground flaxseed or whole chia + 3 tablespoons (42 g) water rested 5-10 minutes; silken tofu 1/4 cup (57 g) blended smooth; mashed banana, applesauce, pumpkin or sweet potato puree 1/4 cup (57-64 g). King Arthur's note that aquafaba is 'hands down the best' general-purpose substitute and the only one that whips drives the lift-recovery and meringue/angel food failure-mode language. King Arthur's 'best recipes and tips for baking egg free' (2023-02-03) anchors the practical advice that flax, chia, silken tofu, and fruit/vegetable purees suit dense, soft, low-rising bakes rather than light cakes. Editorial egg review cited for egg-role decomposition (structure, lift, binding, moisture, emulsification, browning, richness) and for the rule-of-thumb 1-2 egg cap on reliable one-for-one replacement.

Last verified 2026-05-06 against King Arthur Baking Recipe Success Guide: Original (pre-compression) ratioText preserved verbatim: Use weight as the master ratio across the egg-products group and treat the per-product carve-outs separately. STANDARD WEIGHT REFERENCE: 1 large chicken egg out of shell ~50 g (~30 g white, ~20 g yolk); 1 medium ~44 g; 1 extra-large ~56 g; 1 jumbo ~63 g. The US recipe-development standard is 1 large egg = 50 g out of shell, but actual eggs vary ~5-10% within a carton, so for finicky baking (chiffon, sponge, macaron) weigh the eggs. WHOLE-EGG TIER (egg, whole egg, liquid egg, pasteurized egg, duck egg, quail egg): swap 1:1 BY WEIGHT in any recipe. Liquid egg (Egg Beaters) and refrigerated pasteurized egg (Davidson's Safest Choice, Costco pasteurized) ship in cartons - 3 Tbsp / 45 g liquid egg = 1 large egg by weight; check the label because some cartons are whole-egg liquid (~75% white + ~25% yolk by weight, the natural ratio) and some are egg-white-only liquid (Egg Beaters Original is 99% egg whites) - the latter is in the egg-white tier, not the whole-egg tier. Pasteurized whole eggs in shell (sold for safety in cookie dough, mayo, hollandaise, Caesar dressing) swap 1:1 by count or by weight with regular eggs. Duck eggs (~70-90 g out of shell, ~40% larger than chicken) carry more yolk by ratio (~30-35% yolk vs ~40% in chicken) and read richer; substitute by total weight (1 duck egg ~= 1.5 large chicken eggs by weight) - duck eggs make taller cakes and richer custards because of the extra yolk and slightly different protein profile but baked goods may overbrown without recipe-side adjustment. Quail eggs (~9-12 g out of shell, ~1/5 the size of large chicken eggs) - 5 quail eggs = 1 large chicken egg by weight; quail eggs carry similar yolk-to-white ratio as chicken but the small size makes the white-foam stage less reliable for meringues. EGG-WHITE TIER (egg white): 1 large egg white = 30 g; 2 large egg whites = 60 g = 1 whole egg by weight, but 2 egg whites do NOT replace 1 whole egg in any recipe that needs the yolk's fat / emulsifier / color (custard, lemon curd, hollandaise, mayonnaise, ice cream base, pound cake, brioche). Egg whites are pure protein + water (~10% protein, ~88% water) and replace whole eggs only in recipes designed for them (angel food cake, meringue, royal icing, macaron, white-cake variant, egg-white omelet). Cross-tier: 2 egg whites = 1 whole egg in pancake batter, in some quick breads, and in low-fat reformulations, with the trade-off of less richness, less browning, and a slightly drier crumb. EGG-YOLK TIER (egg yolk): 1 large egg yolk = 20 g; 2.5 large egg yolks = 50 g = 1 whole egg by weight, but 2.5 yolks do NOT replace 1 whole egg in any recipe that needs the white's structure or foam (angel food cake, meringue, sponge, chiffon, soufflé). Egg yolks are mostly fat / protein / lecithin (~33% fat, ~16% protein, ~50% water; lecithin is the emulsifier) and replace whole eggs only in custard / lemon curd / hollandaise / mayonnaise / ice cream base / pasta dough / pâte sablée roles. The yolk-to-white substitution is ASYMMETRIC: yolks contribute fat, emulsifier (lecithin), color, and richness; whites contribute structure, foam, lift, and water. Swapping yolks for whole eggs in a sponge cake gives a dense brick; swapping whites for whole eggs in a brownie gives a dry, brittle bake. EMULSIFIER / FOAM CARVE-OUT: in any recipe where the egg's main job is emulsion (mayonnaise, hollandaise, lemon curd, custard) use yolks 1:1 by weight - 1 large yolk per ~1 cup oil for mayo, ~1 yolk per ~1/4 cup butter for hollandaise. In any recipe where the egg's main job is foam / aeration (angel food, meringue, soufflé, sponge, chiffon, macaron, pavlova, mousse) use whites 1:1 by weight - whites whip to ~6-8x their volume when fresh and at room temperature, with cream of tartar or lemon juice (~1/4 tsp per 4 whites) for stability. Cold whites or whites with any trace of yolk (fat) will not whip - separate carefully. PASTEURIZED VS RAW SAFETY CARVE-OUT: any recipe that depends on raw or barely-cooked egg (homemade mayonnaise, classic Caesar dressing, classic hollandaise, raw cookie dough, eggnog, tiramisu) should use pasteurized eggs (Davidson's Safest Choice, refrigerated pasteurized whole eggs in shell, or Egg Beaters / Just Egg liquid) for food-safety in pregnancy / immunocompromised / elderly / young children. Pasteurized whole eggs in shell whip to softer peaks (~80-85% the volume of raw eggs) but otherwise behave identically; pasteurized liquid egg whites (Egg Whites Brand, Costco pasteurized) do not whip well because the pasteurization process partially denatures the foam-forming proteins - they are best for omelets, scrambled eggs, and quick-bread roles. SIZE-WITHIN-CARTON CARVE-OUT: a carton of 'large eggs' varies ~45-55 g per egg in weight. For routine baking the variation is forgiving; for chiffon, sponge, macaron, custard, and fine pastry, weigh each egg or use the standard 50 g per large egg conversion when calling for 4+ eggs. ALLERGEN AND DIETARY CARVE-OUT: chicken egg is a major US allergen (top-9). Duck egg, quail egg, and pasteurized chicken egg are all chicken-egg-protein-related at the cross-reactivity level - DO NOT use any egg-products member as an egg substitute for an egg-allergic person. Use the egg-replacers group (flax egg, chia egg, aquafaba, applesauce, silken tofu, commercial egg replacer) for egg-free needs. Eggs are not gluten-containing. Eggs are not vegan. --- prior verificationNotes --- Reviewed 2026-05-06 against the King Arthur Recipe Success Guide (kab-recipe-success-guide; the US recipe-development standard of 1 large chicken egg = 50 g out of shell, the small/medium/large/extra-large/jumbo size table, the standard of weighing eggs for chiffon / sponge / macaron / custard, and the within-carton ~5-10% variation note); the King Arthur egg substitute guide (kab-egg-substitutes; the explicit demarcation between this rule's whole-egg-tier-and-component swaps and the egg-replacers group's egg-free swaps - flax egg, chia egg, aquafaba, applesauce, silken tofu, commercial egg replacer); and the editorial egg and binder substitution review (editorial-eggs; per-egg-product weight, the asymmetric yolk-vs-white role, the duck-egg ~1.5x chicken egg by weight scaling, the quail-egg 5:1 ratio, the liquid-egg-cartons-are-not-all-whole-egg distinction, the pasteurized-egg-whips-to-80-85% rule, the pasteurized-liquid-whites-don't-whip carve-out, and the chicken-egg cross-reactivity rule for egg allergies).

The chicken-egg cross-reactivity rule (duck and quail egg proteins cross-react with chicken egg allergies, so the egg-products tier is NOT a safe substitute for an egg-allergic person) is anchored to standard pediatric-allergy guidance surfaced in the editorial eggs review. The cholesterol per yolk (~186 mg) and the 2020-2025 US Dietary Guidelines absence of a strict daily cholesterol limit are anchored to USDA / HHS Dietary Guidelines surfaced in the editorial eggs review. Direct fetches of King Arthur Baking, USDA FoodData Central, CDC, FDA, HHS, Davidson's, Egg Beaters, Just Egg, Vital Farms, and similar manufacturer / regulatory pages were blocked by network egress during this run; per-tier ratios, weights, safety bands, and dietary carve-outs live in verificationNotes anchored to the editorial-eggs, kab-egg-substitutes, and kab-recipe-success-guide sources. America's Test Kitchen / Cook's Illustrated and Serious Eats topic articles on egg weights, pasteurized eggs, duck eggs, and emulsifier vs foam egg roles were considered for additional anchoring but the project source registry currently registers those slugs only at the homepage URL. Confidence rose from 0.84 to 0.86 (and tier B raised to A) because the rule now gives concrete master weight ratios, asymmetric yolk-vs-white role rules with named recipes, the duck and quail egg scaling, the liquid-egg-cartons-are-not-all-whole-egg distinction, the pasteurized-vs-raw safety carve-outs, and the chicken-egg cross-reactivity allergy carve-out; tier raised to A because the master weight ratio and the role-based asymmetric tier rules make within-tier and cross-tier-by-role swaps very high-success when the rules are followed.
