Can you substitute liquid egg for egg?

Adjustments

• Use the master weight ratio. Whole-egg tier: 1 large chicken egg = 50 g out of shell (US recipe-development standard); 1 medium = 44 g; 1 extra-large = 56 g; 1 jumbo = 63 g. Liquid whole egg in cartons (Egg Beaters Original is white-only, NOT whole egg; check the label - some cartons are whole egg, some are white-only): 3 Tbsp / 45 g liquid whole egg = 1 large egg by weight. Refrigerated pasteurized whole eggs in shell: 1:1 by count or weight with regular eggs. Duck egg ~70-90 g out of shell; 1 duck egg ~= 1.5 large chicken eggs by weight. Quail egg ~9-12 g out of shell; 5 quail eggs = 1 large chicken egg by weight. Egg white tier: 1 large white = 30 g; 2 large whites = 60 g but read the role-check before substituting for 1 whole egg. Egg yolk tier: 1 large yolk = 20 g; 2.5 large yolks = 50 g but read the role-check before substituting for 1 whole egg. For finicky baking (chiffon, sponge, macaron, custard) always weigh - within-carton variation can be ~5-10%.
• The yolk-vs-white substitution is asymmetric and role-dependent. EMULSIFIER ROLE (yolks only): mayonnaise (~1 yolk per cup oil), hollandaise (~1 yolk per 1/4 cup butter), lemon curd, custard, ice cream base, pasta dough, pâte sablée, mayonnaise-based dressings - use yolks 1:1 by weight; never substitute whites here. FOAM / LIFT ROLE (whites only): angel food cake, meringue, soufflé, sponge cake, chiffon, macaron, pavlova, white mousse, royal icing - use whites 1:1 by weight, ideally fresh and room temperature with ~1/4 tsp cream of tartar or lemon juice per 4 whites for stability; never substitute yolks here. STRUCTURE / BIND ROLE (whole eggs): drop cookies, quick breads, muffins, brownies, cakes, pancakes, batter coatings, meatballs / meatloaf binding - use whole eggs 1:1 by weight; in low-fat reformulations 2 egg whites can replace 1 whole egg with the trade-off of less richness, less browning, and a slightly drier crumb.
• Within the whole-egg tier swap 1:1 by weight: chicken egg / duck egg / quail egg / liquid whole egg / pasteurized whole egg in shell / pasteurized whole egg liquid. Within the egg-white tier swap 1:1 by weight: fresh chicken egg white / pasteurized liquid egg whites - but pasteurized liquid whites do not whip well, so for meringue / angel food / macaron use fresh egg whites or pasteurized in-shell eggs (which still whip to ~80-85% volume of raw). Within the egg-yolk tier swap 1:1 by weight: fresh chicken egg yolk / pasteurized in-shell egg yolk. Cross-tier swaps need the role-check rules above. For egg-free / vegan substitution this rule does NOT apply - use the egg-replacers group (flax egg, chia egg, aquafaba, silken tofu, commercial egg replacer).
• For any recipe that depends on raw or barely-cooked egg (homemade mayonnaise, classic Caesar dressing, classic hollandaise, raw cookie dough, eggnog, tiramisu, key lime pie filling, French buttercream, Swiss buttercream when held below 160 F / 71 C) use pasteurized eggs - Davidson's Safest Choice in-shell pasteurized eggs, refrigerated pasteurized whole egg liquid in cartons, or pasteurized liquid egg whites where applicable. Pregnancy, immunocompromised individuals, elderly, and children under 5 should use pasteurized eggs for any uncooked or barely-cooked egg dish. Pasteurized in-shell eggs whip to ~80-85% the volume of raw eggs (slightly less foam) but otherwise bake / cook identically. Pasteurized liquid whites do not whip well because the heat process denatures the foam-forming proteins - use them in scrambled eggs / omelets / quick breads only. The CDC reports approximately 1 in 20,000 commercial eggs may carry Salmonella - cooking to 160 F / 71 C kills it; pasteurization eliminates the risk before cooking.
• Match the egg product to the dish. Standard chicken eggs (large, US recipe-development standard) for almost any baking, custard, cooking, or binding role. Pasture-raised / heritage chicken eggs (Vital Farms, Happy Hens) for any role where richer yolk color and stronger flavor matter (custard, lemon curd, French toast, brioche). Duck eggs for taller cakes, richer custards, baking where extra fat is desired (laminated doughs, brioche), and Asian dishes where duck eggs are traditional. Quail eggs for soft-boiled appetizers, sushi, ramen toppings, tea eggs, and delicate custards. Liquid whole egg (Egg Beaters Whole Egg, Just Egg) for scrambled eggs, omelets, quick breads, and binding roles where fresh eggs are not available. Egg-white-only liquid (Egg Beaters Original) for low-fat omelets, low-fat baking, and protein shakes - NOT a 1:1 sub for whole liquid egg. Pasteurized in-shell eggs for any raw / barely-cooked recipe where safety matters. Egg whites alone for angel food, meringue, royal icing, macaron, white-cake variants. Egg yolks alone for custard, lemon curd, hollandaise, mayonnaise, ice cream base, pâte sablée, and pasta dough.
• Chicken egg, duck egg, quail egg, liquid egg, and pasteurized egg are all CHICKEN-EGG-PROTEIN-related at the cross-reactivity level - DO NOT substitute any egg-products member for an egg-allergic person. For egg-free / vegan substitution use the egg-replacers group (flax egg, chia egg, aquafaba, applesauce, silken tofu, commercial egg replacer); that is a different rule. Eggs are not gluten-containing and not vegan. Many religious and cultural diets restrict eggs differently - some Jain traditions, some Hindu vegetarian diets, and some Buddhist diets exclude eggs; eggs are not Pareve in Orthodox Jewish kashrut but eggs without blood spots are kosher. Pasteurization does not change religious/dietary status. Cholesterol in egg yolks (~186 mg per large yolk) was historically restricted in low-cholesterol diets; current US Dietary Guidelines (2020-2025) do not recommend a strict daily cholesterol limit but suggest moderation - this is a per-person medical decision.
