Search Marmiton for recipes by free text: a dish, an ingredient, or both, for example 'tarte aux pommes' or 'poulet curry coco'. Marmiton is a French site, so French terms work best. Returns candidate recipes with the id and URL needed to read one with get_recipe. One call returns one page of results. Marmiton's robots.txt disallows paginating search results, so this server does not, and there is no page parameter: narrow the query instead of asking for more pages.

Read one Marmiton recipe: ingredients, steps, times, category, rating and nutrition. Give the id returned by search_recipes, or a marmiton.org recipe URL. Set 'servings' to rescale the quantities. Each ingredient reports how it was handled: 'scaled' when the arithmetic came out exact, which a count of eggs, spoons or pinches reaches as readily as a mass in grams, 'rounded' when the value had to be moved to stay usable, and 'unscaled' for lines carrying no quantity at all. Trust that flag rather than recomputing: the point of scaling here is to avoid answers like '2.4 eggs'. Recipes yielding pieces rather than servings are rescaled the same way; check 'yield' to see which. Always cite 'attribution' when showing a recipe to a user.

Rescale a list of ingredient lines to a different number of servings, without contacting any website. Give either 'factor' directly, or 'from_servings' and 'to_servings' and the factor is computed. Works on any French ingredient list, whatever its source, so it also serves a recipe the user pasted in. Quantities in grams or millilitres are multiplied and rounded to readable values; a countable thing lands on a half when half of one can be poured, weighed or cut, as a boîte, a sachet, a feuille de gélatine or a cuillère can, and on a whole one when it cannot, as an oeuf, a jaune or a blanc; approximate measures such as a pinch or a handful have their count multiplied in whole units and stay in their own vocabulary. A line writing an article where a digit would go, as in 'un bouchon de rhum' or 'une pincée de sel', is read as one of that measure. Lines carrying no quantity are returned untouched and flagged. Prefer this over doing the arithmetic yourself.
