| Canola oil | 1 cupper 1 cup vegetable oilWorks | Any recipe at all, baking or frying, where you want no flavour of its own, when you want the swap nobody at the table will detect | This is the one genuinely invisible swap on the page. If you have canola oil, stop reading and use it. |
| Sunflower oil | 1 cupper 1 cup vegetable oilWorks | When canola is not in the cupboard but sunflower is | Cold-pressed sunflower oil is a different product with a definite seedy flavour and a lower smoke point. |
| Light (refined) olive oil | 1 cupper 1 cup vegetable oilTweak it | Baking, when the only oil in the house is olive oil, shallow and deep frying at high temperatures | Refined olive oil has the highest smoke point of the common household oils, which makes it a better frying oil than most people assume. |
| Avocado oil | 1 cup refined avocado oilper 1 cup vegetable oilWorks | Searing in a screaming hot pan, where anything else would smoke, when you want a neutral oil that will not break down over a long fry | Its selling point is heat, not flavour. If nothing in your recipe goes above 400F, canola does the same job for a fraction of the price. |
| Grapeseed oil | 1 cupper 1 cup vegetable oilWorks | Vinaigrettes and mayonnaise, where its thin body is an advantage, stir-frying and pan-searing up to about 400F | Its light body is the reason restaurant kitchens reach for it in dressings and homemade mayonnaise. |
| Peanut oil | 1 cup refined peanut oilper 1 cup vegetable oilTweak it | Deep frying, where its stability over a long fry is the point, wok cooking at high heat | The reason to choose it is that it holds up over repeated frying better than most seed oils do. |
| Melted butter | 1 ¼ cups, melted and cooled slightlyper 1 cup vegetable oilTweak it | Brownies, muffins and quick breads you want to taste richer | The one real trade-off is fridge texture. |
| Extra virgin olive oil | 1 cupper 1 cup vegetable oilYou'll taste it | Savoury cooking of any kind, where the olive flavour is welcome | The old claim that extra virgin olive oil cannot be cooked with is overstated. |
| Melted coconut oil | 1 cup, melted and measured liquidper 1 cup vegetable oilYou'll taste it | Vegan bakes where you want a firmer, crisper result | The 76F melting point is the catch that surprises people: the batter behaves like an oil batter and the finished cake behaves like a butter cake. |
| Unsweetened applesauce | ½ cup plus ½ cup oilper 1 cup vegetable oilYou'll taste it | Halving the fat in a muffin, spice cake or quick bread | The reason all-applesauce bakes disappoint is not moisture but tenderness: with no fat coating the flour, the gluten develops fully and the crumb goes tough. |
| Mashed ripe banana | ½ cup mashed very ripe banana plus ½ cup oilper 1 cup vegetable oilYou'll taste it | Banana bread, spice muffins and oat bakes where banana suits the flavour, using up overripe bananas while cutting some of the fat | Banana browns the crumb as well as flavouring it, so a pale vanilla cake made this way will not look like the picture in the recipe. |
| Water or broth | 2-3 tbsp water or broth, added a splash at a time as the pan driesper 1 tbsp vegetable oil for sauteingYou'll taste it | Softening onions, garlic or greens when there is no fat in the house | Listed here because people search for it. It is a real technique for softening vegetables and nothing more. |
