Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

convert

convert_ingredient

Converts a kitchen amount between volume and weight for a specific ingredient, using measured grams-per-cup values (USDA FoodData Central portion weights with FDC ids, and the King Arthur Baking ingredient weight chart) instead of guessed densities. 271 ingredients. Units: US cup (236.5882365 mL), metric cup (250 mL), imperial cup, US legal cup (240 mL), Japanese cup, US/metric/Australian tablespoons, teaspoons, US and imperial fl oz, pints, quarts, gallons, mL, dL, L, g, mg, kg, oz, lb and sticks of butter. Volume to volume and weight to weight need no ingredient. States which cup definition it used and cites the density source.

convert_oven_temperature

Converts an oven setting between Fahrenheit, Celsius and UK gas mark (1/4 to 10, from the standard recipe table) and optionally adjusts for a fan (convection) oven by 20 C, the manufacturer guidance. Returns the nearest gas mark and whether it is an exact table value.

ingredients

search_ingredients

Fuzzy search over the ingredient table (flours, sugars, fats, dairy, liquids, nuts, grains, fruit, produce). Returns canonical names, grams per US cup and per tablespoon, and the source (USDA FDC id or King Arthur Baking chart). Use it to pick the exact ingredient before converting.

scale

scale_recipe

Scales a list of recipe ingredient lines ("1 1/2 cups all-purpose flour", "2 tbsp honey", "3 eggs") by a factor or from original to target servings. Parses mixed numbers and fraction characters. With to_metric_weights, converts cup and spoon amounts to grams with the measured density table and weights to grams, and reports lines it could not match.
