QUICK ANSWER
The swaps people need most: buttermilk = milk + 1 tbsp lemon juice per cup; baking powder = ¼ tsp baking soda + ½ tsp cream of tartar per teaspoon; heavy cream (for cooking) = ¾ cup milk + ¼ cup melted butter; 1 tbsp fresh herbs = 1 tsp dried.
Baking.
| Instead of | Use | What changes |
|---|---|---|
| Buttermilk (1 cup) | 1 cup milk + 1 tablespoon lemon juice or white vinegar | Stir and let it stand 5–10 minutes until slightly thickened. |
| Baking powder (1 teaspoon) | ¼ teaspoon baking soda + ½ teaspoon cream of tartar | Mix just before using; it reacts as soon as it gets wet. |
| Self-rising flour (1 cup) | 1 cup all-purpose flour + 1½ teaspoons baking powder + ¼ teaspoon salt | Whisk well so the leavening is evenly spread. |
| Brown sugar (1 cup) | 1 cup granulated sugar + 1 tablespoon molasses | Use 2 tablespoons of molasses for dark brown sugar. |
| Powdered sugar (1 cup) | 1 cup granulated sugar + 1 tablespoon cornstarch, blended until fine | A blender or spice grinder works; a food processor gives a coarser result. |
| Egg (1, as a binder) | 1 tablespoon ground flaxseed + 3 tablespoons water | Rest 5 minutes. Works for binding in muffins and pancakes, not for whipped or egg-led recipes. |
Dairy.
| Instead of | Use | What changes |
|---|---|---|
| Heavy cream (1 cup, for cooking) | ¾ cup milk + ¼ cup melted butter | Good in sauces and soups. It will not whip. |
| Sour cream | Plain Greek yogurt, same amount | Tangier and leaner; stir in off the heat so it does not split. |
| Mayonnaise (in dips and dressings) | Plain Greek yogurt, same amount | Season a little more; yogurt is less rich. |
Pantry.
| Instead of | Use | What changes |
|---|---|---|
| Cornstarch (1 tablespoon, for thickening) | 2 tablespoons all-purpose flour | Cook a couple of minutes longer to lose the raw-flour taste. |
| Beef bouillon cube (1 cube + 1 cup water) | 1 cup beef broth or stock | Taste before salting: cubes are saltier than most broths. |
| Soy sauce | Tamari (same amount) or coconut aminos | Tamari is usually gluten-free; coconut aminos are sweeter and less salty. |
| Honey | Maple syrup, same amount | Slightly thinner, with its own flavour. |
| Panko, crushed crackers or quick oats | Use about the same volume. |
Acids and vinegars.
| Instead of | Use | What changes |
|---|---|---|
| Lemon juice | Lime juice, same amount; or white wine vinegar, half the amount | Vinegar is sharper, so start with less. |
| Rice vinegar | Apple cider vinegar or white wine vinegar | Add a pinch of sugar; rice vinegar is milder and slightly sweet. |
| Tarragon vinegar | White wine vinegar + a pinch of dried tarragon | Champagne vinegar also works without the herb note. |
| Wine (in a sauce or braise) | Broth or stock + a splash of vinegar | Chicken or vegetable broth for white wine; beef broth for red. |
Herbs and aromatics.
| Instead of | Use | What changes |
|---|---|---|
| Fresh herbs (1 tablespoon) | 1 teaspoon dried herbs | Dried herbs are stronger; add them earlier in cooking. |
| Garlic (1 clove) | ⅛ teaspoon garlic powder | Add with the liquid so it does not scorch. |
Substitutes behave best in forgiving dishes: soups, sauces, stir-fries and quick breads. In precise baking such as cakes, meringues and laminated doughs, a swap can change rise and texture, so buy the real ingredient when the result matters.
Common questions.
What can I use instead of buttermilk?
1 cup of milk with 1 tablespoon of lemon juice or white vinegar, left to stand 5–10 minutes. Plain yogurt thinned with a little milk also works.
What is a substitute for beef bouillon cubes?
Use 1 cup of beef broth or stock in place of each cube plus its cup of water. Bouillon is saltier, so taste before adding salt.
What can I substitute for tarragon vinegar?
White wine vinegar with a pinch of dried tarragon. Champagne vinegar is a milder option without the herb.
Can I use flour instead of cornstarch?
Yes, for thickening: 2 tablespoons of flour for every tablespoon of cornstarch, and simmer a little longer.
How much dried herb replaces fresh?
About one third: 1 teaspoon of dried for 1 tablespoon of fresh.
What can I use instead of an egg?
For binding, 1 tablespoon of ground flaxseed mixed with 3 tablespoons of water per egg. It will not replace eggs in recipes built on them, like omelettes or meringues.
