Identify your dish: marinade/sauce, glaze, sandwich/cheese board, or baking (cakes/biscuits/loaves).
Pick the substitute that matches the role: jam-preserve for baking texture, chutney for flavor, salsa/chili sauce for quick savory tang.
Use the listed ratio; for jams/preserves, stir in lime/lemon or vinegar to recreate chutney’s tang.
Adjust spice last: add grated ginger, a pinch of chili, or a small amount of curry powder if your original chutney was strongly spiced.
Taste-test before committing: it should read sweet + tangy + warm; if flat, add acid (citrus/vinegar) by small increments.
