for marinade.
Marinades use baking soda as a denaturant: at 1 tsp per pound of beef for 15-20 minutes, surface pH climbs above 8.5, myosin unwinds, and water is pulled inward so the steak sears juicier. Over 30 minutes the exterior turns mushy — time is the variable, not dose. Subs must match that pKa-driven penetration without adding sugar that burns at sear temps or salt that draws water the wrong direction.

adjustment for marinade
For a 20-minute beef velvet marinade, use 3 tsp baking powder per 1 tsp soda and skip any lemon or wine vinegar. Penetration depth reaches about 2mm in that window — shallower than pure soda's 3mm — because the built-in acid buffers pH at 6.8 and blunts myosin denaturation.

Egg
5.01 tsp : 1/4 tsp
Whipped egg whites add lift in cakes and souffles when baking soda is unavailable

adjustment for marinade
Whisk 1 whole egg per pound of beef for a velveting marinade — classic Cantonese technique. Protein coats surface, trapping moisture through a high-heat sear, but no pH shift means penetration stays at 1mm over 20 minutes. Rinse unnecessary; cornstarch slurry often pairs for full velvet.

Buttermilk
5.01/2 tsp : 1/2 tsp
Replace liquid with buttermilk and add baking powder; acid reactivates leavening

adjustment for marinade
Buttermilk brine at pH 4.6 tenderizes via lactic acid over 4-12 hours at 38F — opposite mechanism from soda's 20-minute alkaline shock. Penetration is slower (about 3mm in 6 hours) but gentler; surface won't mush even at 24 hours, making it the safer overnight hold.
