When the best swap works
- Olive oil chiffon cake or lemon olive oil cake — the 1:1 weight swap holds because both oils are 100% fat with near-identical density at 0.91 g/mL.
- Vinaigrettes and mayonnaise where you wanted neutrality — light olive oil reads as background, especially when balanced with a sharp acid like sherry vinegar at a 3:1 ratio.
- Quick breads like banana bread or zucchini bread where the oil's only job is moisture and tenderness, not high-heat searing or distinct flavour.
