Identify what you need hot sauce to do in your recipe: tang-forward heat, smoky depth, or chili-garlic punch.
Choose the closest option from the list and match the ratio: start at ¾:1 for paste-based swaps and 1:1 for pourable sauces.
Thin paste/condiment swaps with warm water 1 teaspoon at a time until the mixture pours and coats a spoon like your original hot sauce.
Add most of it first, then adjust heat at the end so you don’t overshoot the spice level.
Taste for balance: if it’s missing tang, add a few drops of vinegar or lemon; if it’s too sweet, add salt.
