Search the Wikibooks Cookbook for a recipe, by dish name or by an ingredient it uses. 'text' searches the whole of each page, which is what finds a dish from an ingredient inside it; 'title' matches the page name only, which is exact and misses a dish the Cookbook names differently. The Cookbook also holds reference pages on ingredients, techniques and cuisines, and those rank alongside recipes: a row is a page, and only get_recipe can say whether it carries an ingredient list. A full-text row can be a page that merely names the dish: when the titles do not say the words searched for, the notes say so, because the Cookbook links to dishes it does not hold. 'total_available' is null because the search route reports no total and offers no second page. Narrow the query rather than asking for more. Every row carries an 'id', which get_recipe takes.

Read one Wikibooks Cookbook page: ingredients, equipment, steps, yield, time, difficulty, category, and the nutrition panel when the page carries one. 'id' is the page key from search_recipes or list_recipes, such as 'Cookbook:Spaghetti_alla_Carbonara'. A plain dish name is accepted and the Cookbook namespace is added. Pass 'servings' to rescale: countable things land on whole or half units, a measurement is moved to a smaller unit before rounding so nothing disappears, and anything that cannot be multiplied is flagged instead. Read 'scaling' on each ingredient rather than doing the arithmetic yourself. Rescaling needs a yield to scale from. A page that states none comes back as published, and says so. A page yielding no quantities is answered with 'factor' 1 and a note: an empty ingredient list was multiplied by nothing. 'author' and 'rating' are always null: the Cookbook is written collectively and carries no reader score. A time the page does not state is null, never zero, and never inferred from the steps. Pages are published under a licence that requires attribution; 'license' and 'url' carry what to credit.

Rescale a list of English ingredient lines. This contacts no website and works on a list from anywhere, including one the user pasted in. Give either 'factor' directly, or 'from_servings' and 'to_servings' and the factor is computed. Grams, millilitres, ounces and pounds are multiplied and rounded to what a scale can show; a quantity that would fall below one is moved to a smaller unit first, so it never rounds away to nothing. Countable things land where a kitchen can follow: an egg, a yolk or a white on a whole one, a clove or a spoon on a half, which is what stops an answer like '2.4 eggs'. An approximate measure is scaled as a count, so a pinch taken from 6 servings to 25 is 4 pinches; the note gives the everyday equivalence, and the quantity stays in the unit the line used. That covers the gestures, such as a pinch, a dash, a glug or a handful, and anything named after what holds it, such as a capful or a spoonful. A line with no quantity at all comes back untouched and flagged. A bracketed equivalent, as in '450 g (1 pound)', is scaled with the amount it restates rather than left to contradict it, and so is one written after a slash, as in '500 g / 1.1 lb'. A line offering a choice, as in '2 tablespoons butter OR 30 g margarine', has both branches scaled, so whichever one the cook takes carries the same share. Prefer this over doing the arithmetic yourself.

Browse the Wikibooks Cookbook by cuisine, by kind of dish, or by main ingredient. Give at least one of the three; giving several narrows the result. This is built on the Cookbook's search, because the route this server is allowed to use publishes no way to list the members of a category. What comes back is therefore a ranked sample and not the category itself: it is neither complete nor ordered, and its length says nothing about how many recipes the Cookbook holds on the subject. The Cookbook also holds reference pages on ingredients and techniques, and those rank alongside recipes. Open a row with get_recipe before describing it as a recipe. Use search_recipes instead when there is a dish name to look up.
