Commercial egg replacer; follow box ratio, works for binding and lift in most baking

egg substitute
for marinade.
Marinades use eggs less for flavor and more for the denaturation handshake: yolk lecithin and 9% protein carry acid (lemon, buttermilk, yogurt) into the first 3-4mm of muscle over 4-24 hours. Penetration stalls past 5mm because myofibrils block diffusion. This page ranks substitutes by acid carrying capacity at pH 4.0-5.5, how aggressively they denature surface protein in 60 minutes, and whether their salt ceiling (safe below 1.8% by weight) produces ham-cure texture on chicken breast.

adjustment for marinade
Commercial replacer in marinades acts as a binder that holds spice rubs to meat surface for the first 4 hours. No enzymatic tenderizing — penetration stalls at 2mm. Salt ceiling sits at 1.5% before the starch base turns gluey on the surface; don't exceed 24-hour marinate or the coating slumps and slides off during sear.

Greek Yogurt
5.01/4 cup : 1 cup
1/4 cup per egg, adds moisture and binding
5.0
adjustment for marinade
1/4 cup yogurt per egg in a marinade drives tandoori-style tenderizing: pH 4.3 denatures surface proteins to 3-4mm depth over 6-12 hours. Salt at 1.2% by weight is the ceiling before casein locks too tightly and surface reads rubbery after searing. Adds lactic tang that carries cumin, coriander, and garlic deep into the muscle.
03
Tofu
5.01/4 cup : 1 cup
Blend silken tofu smooth, 1/4 cup per egg
5.0
adjustment for marinade
Blended silken tofu (1/4 cup) doesn't penetrate — it coats. Builds a 1-2mm protein layer that shields meat from 1.5% salt during a 4-hour marinade, preventing ham-cure texture on chicken breast. No acid, so pair with 1 tbsp lemon juice per 1/4 cup to reach pH 5.0 for mild tenderizing without over-denaturing to 4mm depth.

Buttermilk
4.01/4 cup : 1 cup
Adds tangy moisture; 1/4 cup replaces 1 egg in pancakes and cakes, tenderizes crumb
4.0
adjustment for this dish
1/4 cup buttermilk per egg is the classic Southern-fry tenderizer: pH 4.4 drives protein denaturation to 5mm depth over 8-24 hours on chicken thighs. Salt-tolerant to 1.5% without curdling on the meat surface. Tangy carry-through survives a 375°F fry because 20% of the acid volatilizes before reaching the crust interior.
