🟢scale_recipe(ingredients, from_servings, to_servings)
Scale every ingredient in a recipe from one serving count to another (0.1x to 20x), with kitchen-friendly fraction hints; items without a quantity pass through unchanged. Use when cooking for more or fewer people. Do NOT use to change units (use convert_units) or to combine several recipes' ingredients (use merge_shopping_list).

}🟢convert_units(value, from, to, ingredient)
Convert one cooking amount between units: within volume or weight exactly, or between volume and weight using a built-in density for flour, sugar, brown sugar, butter, water, milk, rice, oats, cocoa or honey. Use for questions like 'how many grams is 2 cups of flour'. Do NOT use to change serving counts (use scale_recipe).

}🟢merge_shopping_list(lists)
Combine several shopping or ingredient lists into one, summing the same item across lists (volumes and weights converted to a friendly unit) and noting which list each came from. Use when shopping for several recipes or meals at once. Do NOT use to resize one recipe (use scale_recipe) or price it (use cost_per_serving).

}🟢cost_per_serving(ingredients, servings, currency)
Total the cost of a recipe's ingredients and work out the cost per serving and per 10 servings. Use when budgeting a dish, pricing meal prep or comparing recipes on cost. Do NOT use to resize the recipe (use scale_recipe first, then price the scaled amounts here).
