Crisp outside, soft inside: liquid, egg, fat and leavening per 100 g of flour.
455 recipes from 145 sites, each reduced to grams and written as baker's percentages: grams of each ingredient per 100 g of flour, so a small recipe and a double batch line up. Below: the typical batch, how far recipes stray from it, and a page for every recipe with a link to the original.

The median of all 455 recipes for each ingredient, scaled to 250 g of flour. No single recipe is exactly this: each line is the middle of its own distribution. “Most recipes” means the middle half, from the 25th to the 75th percentile.
| Ingredient | Grams |
|---|---|
| FlourThe scale for everything else | 250 gabout 2 cups |
| LiquidMost recipes use 270 to 450 g | 375 gabout 1 1/2 cups |

Volumes are approximate: flour at 125 g a cup, sugar 200 g, butter or oil 225 g, milk and other liquids 240 g, a large egg 50 g.
Each dot is a recipe, placed by grams of the ingredient per 100 g of flour (100% would be as much as the flour). The shaded band is the middle half of recipes and the line is the median.

Milk or buttermilk; a thinner batter spreads across the iron and crisps more.

Waffles carry more fat than pancakes; that is what fries the outside crisp in the iron.

A little sugar browns the grid; too much and it scorches before the inside sets.

Baking powder for quick waffles; yeasted overnight batters rise on yeast instead.

Measured by how far apart the 25th and 75th percentile recipes are. The widest gaps are where the choice of recipe matters most.
Recipes agree most on egg and liquid: egg 37 to 53%, liquid 107 to 181% for the middle half.
455 of the recipes come in 7 languages with enough of each to compare: English 238, French 67, German 60, Dutch 32, Portuguese 30, Spanish 18, Italian 10.
English recipes whose titles use a word, against the ones that do not. What recipe writers do when they pick the word, not proof that it makes the texture.
Recipes called “homemade” (16), “easy” (11) or “best” (10) use about the same amounts as the rest on every ingredient measured here.

77 waffle recipes have 50 or more reader ratings. A rating count says how many people rated a page, which follows its traffic more than its quality. Against the other 378, medians per 100 g of flour, compared within each language:
On no ingredient do the most-reviewed recipes differ from the rest by more than chance would explain.

In 7 languages: English 238, French 67, German 60, Dutch 32, Portuguese 30, Spanish 18, Italian 10. Lines in other languages are read in their own units and words, and each recipe page links to the original. 145 sites in all. No site contributes more than 12 recipes.
Every ingredient line is converted to grams and grouped (butter and oil count as fat; white, brown and liquid sweeteners as sugar), then divided by the flour weight. That baker's percentage is the only comparison that holds across recipes of different sizes.
94% of the 4,308 ingredient lines got a weight. 24% of those weights were printed by the source; the rest were converted from cups and spoons with standard densities, so treat single recipes as close, not exact. Frosting, glaze, streusel and other toppings are listed on each recipe page but left out of the percentages.
A recipe outside the plausible range for any ingredient is left out rather than allowed to stretch every chart; it is usually a different dish with the same name or a misread line. Of the pages fetched, 536 were left out: 275 outside the plausible range on some ingredient (liquid 141, fat 60, sugar 52, egg 11, salt 11), 129 with no flour, or none that could be weighed, 72 with a title that names a different dish, 22 too many lines without an amount, 17 made from a boxed mix, 14 duplicates of other pages, 4 with an ingredient in amounts that could not be weighed, 2 a listing page, not a recipe page, and 1 over the 12-per-site cap.
Every recipe page links to the original, which is where the method is. Recipe Lab does not republish instructions or photos.
