NAME

foodratio - calculate ingredient ratios

SYNOPSIS

$ cat recipe
1 egg   wet
2 water wet
4 flour dry
$ foodratio recipe
$ foodratio --ratio id:flour recipe
$ foodratio --mass 55 --weigh group:wet recipe

DESCRIPTION

Given a list of measurements of ingredients, foodratio will calculate the ratio between those various inputs, optionally using some ingredient (or group of ingredients) as the ratio key. The weights can be recalculated based on the measurement of a particular ingredient.

The input should be in columns, with the mass (or whatever measurement) as the first column. This must be a strictly positive number. If the second column contains % it will be ignored, on the presumption that that is a ratio. Thus the name (id) of the ingredient will come from either the second or third column. The remainder of the columns, if any, will be treated as group names that collect ingredients into groups, e.g. a custom flour group for recipes with different types of flour, or so forth.

Options

mass positive-number

Sets the mass for the weigh method; ingredient measurements will be recalculated based on this amount.

ratio key:value

Sets the ingredient or ingredient group to use as the key value for the ratio calculation, e.g. flour in a bread recipe and not the default total mass. key must be id or group.

weigh key:value

Sets the ingredient or ingredient group to use as the basis for the mass argument, which by default is otherwise the total mass.

EXAMPLE

Given a file containing

160 cornmeal flour dry
150 flour flour dry
11 bpowder dry
3.5 salt dry
30 sugar dry
250 milk wet
70 oil fat wet
58 egg wet

one may weigh an egg and discover that it is 55 grams, and rescale the recipe based on that

$ foodratio cornbread    | grep cornmeal
160     21.84%  cornmeal        flour   dry
$ foodratio --mass 55 --weigh id:egg cornbread  | grep cornmeal
151.7   21.84%  cornmeal        flour   dry

and know to use 152 grams of cornmeal instead of 160.
