The median of all 261 recipes for each ingredient, scaled to 500 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.

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.

Focaccia is among the wettest doughs; high water gives the airy, bubbly crumb.

Oil in the dough, not counting the pan and the top: it makes the crumb tender and rich.

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 water and salt: water 63 to 81%, salt 1.6 to 2.3% for the middle half.
257 of the recipes come in 6 languages with enough of each to compare: English 113, Italian 46, French 37, German 32, Dutch 18, Portuguese 11.
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 “easy” (15) or “no-knead” (10) use about the same amounts as the rest on every ingredient measured here.

43 focaccia 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 218, medians per 100 g of flour, compared within each language:

226 of 261 recipes state an oven temperature, and 32% of those bake at 400°F (205°C). The middle half bake at 400 to 450°F. The other 35 do not say.
245 recipes state a bake time. Taking the middle of any stated range (“55 to 65 minutes” counts as 60), the median is 24 minutes and the middle half bake 20 to 30 minutes.
The single most common pairing is 400°F for 20 to 30 minutes, with 35 of the 220 recipes that state both.
Nearest the median on every ingredient at once.
In 7 languages: English 113, Italian 46, French 37, German 32, Dutch 18, Portuguese 11, Spanish 4. Lines in other languages are read in their own units and words, and each recipe page links to the original. 107 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.
84% of the 2,358 ingredient lines got a weight. 46% 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, 499 were left out: 339 outside the plausible range on some ingredient (water 127, olive oil 95, salt 72, yeast 27, sugar 18), 69 with no flour, or none that could be weighed, 63 too many lines without an amount, 19 with a title that names a different dish, 4 with an ingredient in amounts that could not be weighed, 4 duplicates of other pages, and 1 a listing page, not a recipe page.
Every recipe page links to the original, which is where the method is. Recipe Lab does not republish instructions or photos.
