Visual Guide to Types of Eggs: Comparing Yolks, Shells, and Cooking Performance
Different poultry species produce wildly divergent physical and chemical profiles. The following breakdown illustrates the physical metrics that determine how each egg behaves under heat.
| Egg Variety | Average Weight | Yolk-to-White Ratio | Shell Attributes | Optimal Culinary Use |
|---|---|---|---|---|
| Standard Chicken (Grade AA) | 50, 55g | 1:2 (33% yolk) | 0.35, 0.40 mm; smooth, porous | Everyday scrambling, classic soufflés, standard baking |
| Duck (Pasture-Raised) | 70, 85g | 1:1.3 (43% yolk) | 0.50, 0.58 mm; waxy cuticle, low porosity | Choux pastry, rich custards, gluten-free baking |
| Coturnix Quail | 9, 12g | 1:1.5 (40% yolk) | 0.20, 0.22 mm; thin, heavily pigmented | Canapés, steak tartare garnish, pickling |
| Domestic Goose | 140, 180g | 1:1.1 (48% yolk) | 0.60, 0.70 mm; extremely rigid, chalky | Fresh pasta dough, robust single-pan scrambles |
| Ostrich | 1,200, 1,500g | 1:1.8 (35% yolk) | 1.80, 2.10 mm; porcelain-like, dented pores | High-volume banquet frittatas, novelty baking |
