Choose your use-case: spreading (sandwich/wrap), dressing (salad), or saucing (hot or mixed sauces).
Use the listed ratio for your starting amount of mayonnaise, then check thickness against your goal.
Adjust flavor with a small acid boost: lemon juice or vinegar (start with 1-2 teaspoon per ½ cup) and a pinch of salt if needed.
For any option that’s thinner or looser, let it rest 5 minutes so it thickens; for overly thick swaps, whisk in 1 teaspoon water at a time.
If using for warm dishes, avoid high-heat cooking with yogurt/tofu unless you reduce heat and stir gently to prevent separation.
