Identify the role of Pinot Grigio in your recipe: acidity, complexity, or liquid volume.
For acidity and complexity, choose dry vermouth or chardonnay; for sharp acidity without alcohol, use white wine vinegar mix; for no alcohol option, select broth with lemon.
Prepare substitutes accordingly: dilute white wine vinegar with water (1 tablespoon vinegar to 3 tablespoon water) or mix apple juice and lemon juice in a 3:1 ratio.
Use equal parts substitute to replace Pinot Grigio where ratios are 1:1; adjust based on recipe needs and taste as you cook.
When cooking, allow liquid to reduce if using substitutes with complexity, like dry vermouth, to enhance flavors and avoid overwhelming delicate dishes.
Taste your dish as you cook and adjust acidity or liquid gradually to maintain balance without overpowering the recipe.
