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' for grams and millilitres, 'rounded' for countable things such as eggs or spoons, and 'unscaled' for lines with no quantity or with an approximate one such as a pinch of salt. 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; countable things such as eggs or spoons are rounded to whole or half units; lines with no quantity, or with an approximate one such as a pinch, are returned untouched and flagged. Prefer this over doing the arithmetic yourself.
