Frequently asked questions
Which ingredients does the guide cover?
Ten: butter, eggs, all-purpose flour, sugar, milk, buttermilk, baking powder, sour cream, vegetable oil and honey. Each has one primary swap, one secondary swap and a note, all typed into the code. There is no search and no entry for anything outside this list, such as cream, yeast, cornstarch or chocolate.
Does the amount I enter change the swap?
No. The amount and unit are only repeated back as "Amount in Your Recipe". The ratios stay as written, for example "1/4 cup unsweetened applesauce per egg", so you multiply them yourself. For 3 eggs that means 3 times the per-egg figure, and for 2 tsp of baking powder it means double each part of the mixture.
Why does the flour entry only list gluten-free options?
The all-purpose flour entry offers a 1:1 gluten-free blend, a rice flour and potato starch mix, and almond flour in the notes. It does not offer whole wheat, bread flour or cake flour swaps, so use it only when the goal is to avoid wheat flour.
Are cups, tablespoons and grams converted?
No. The swaps are given in cups, tablespoons and teaspoons, and there is no ingredient density table. If your recipe uses 200 g of sugar, the tool cannot tell you how many cups of honey that is. Weigh or convert the original to a volume first and apply the printed ratio to it.
How do the buttermilk and baking powder swaps work?
For buttermilk the primary swap is 1 cup of milk with 1 tbsp of lemon juice or white vinegar, left for 5 minutes, and the secondary is plain yogurt thinned with a little milk. For baking powder the primary is ¼ tsp baking soda with ½ tsp cream of tartar per 1 tsp of baking powder, and the secondary replaces the cream of tartar with ½ tsp white vinegar.
What does the guide say about egg replacements?
It lists ¼ cup unsweetened applesauce per egg first and 3 tbsp aquafaba per egg second, and mentions a flax egg of 1 tbsp ground flax with 3 tbsp water. The note says these suit muffins, cakes and quick breads and are not ideal where eggs provide structure, such as soufflés and meringues.
Will the substitute behave exactly like the original?
Not necessarily. The notes mention changes in moisture, density, browning and flavour, and the guide has no testing data behind the ratios. Treat them as commonly used starting points, try small batches before an important bake, and check labels if you are swapping for an allergy or medical reason.
Ten common baking and cooking swaps, as the guide lists them
What the guide contains
Pick one of ten ingredients and the tool returns a primary swap, a secondary swap and a note about how it behaves. All of it is fixed text stored in the code rather than calculated, so nothing changes with the amount and unit you enter. Those two fields only echo your quantity back as a reminder, and the ratio you read must be scaled to your recipe by hand. Everything else about the output is the same whatever number you type.
Primary swap for each ingredient
Here is the first-choice replacement the guide gives for every entry. Where the guide says "per", the ratio is per unit of the original ingredient.
| Ingredient | Primary substitute |
|---|---|
| Butter | Equal amount of margarine (1:1) |
| Eggs | ¼ cup unsweetened applesauce per egg |
| All-purpose flour | Equal amount of 1:1 gluten-free flour blend |
| Sugar | ¾ cup honey per 1 cup sugar, with ¼ cup less other liquid |
| Milk | Equal amount of oat, almond or soy milk |
| Buttermilk | 1 cup milk + 1 tbsp lemon juice or white vinegar, rested 5 minutes |
| Baking powder | ¼ tsp baking soda + ½ tsp cream of tartar per 1 tsp |
| Sour cream | Equal amount of full-fat plain Greek yogurt |
| Vegetable oil | Equal amount of melted coconut oil |
| Honey | 1 cup maple syrup per 1 cup honey |
Worked example: 1.5 cups of buttermilk
Selecting Buttermilk and entering 1.5 cups returns "1 cup milk + 1 tbsp lemon juice or white vinegar (let sit 5 minutes)" as the primary swap and plain yogurt thinned with a little milk as the secondary. The echo line reads "1.5 cup of buttermilk". The ratio is written for one cup, so for 1.5 cups you would use 1.5 cups of milk with 1.5 tbsp of lemon juice or vinegar. The note adds that the acid is what activates baking soda, so the note says to always use an acidic substitute.
Worked example: 2 tsp of baking powder
Choosing Baking Powder with 2 tsp returns ¼ tsp baking soda with ½ tsp cream of tartar per 1 tsp of baking powder, and a vinegar variant in second place. The tool repeats "2 tsp of baking powder", but it does not double the mixture. Doubling gives ½ tsp baking soda plus 1 tsp cream of tartar. The note says to add vinegar to the wet ingredients rather than the dry ones, and that self-rising flour already contains baking powder.
Limits to keep in mind
Ten ingredients, two swaps each, and no knowledge of your specific recipe is the whole scope. The guide cannot convert weights to cups, cannot say whether a given recipe will tolerate the change, and cannot cover allergies or medical needs. Delicate bakes such as meringues, soufflés and macarons are the least forgiving, whereas muffins, quick breads and stews usually tolerate more adjustment.
