Unsweetened Cocoa Powder (Best Option)
1 tablespoon per 1 ounce of dark chocolateUnsweetened cocoa powder contains the concentrated chocolate solids that provide the bitterness and roasted flavor notes found in dark chocolate. Since Pad Thai uses dark chocolate sparingly for depth, cocoa powder delivers these characteristics without adding sweetness or dairy.
To replicate the fat content, add about 1 teaspoon of neutral oil (like vegetable or peanut oil) per tablespoon of cocoa powder. Stir well to avoid clumping and ensure even distribution in the sauce.
The final dish will have a slightly sharper chocolate note compared to melted dark chocolate but will maintain the intended savory complexity and balance.
