NAME

Convert::CookingTimes - work out cooking times adjusted for temperature

SYNOPSIS

Given a set of item names, temperatures and durations, works out the average temperature and adjusts the times to suit that temperature, then returns a list of suggested timings.

my ($temperature, @steps) = @steps = Convert::CookingTimes->adjust_times(
    { name => 'Chicken breasts', temp => 200, time => 20 },
    { name => 'Chips', temp => 220, time = 25 },
);
say "Warm oven up to $temperature degrees first.";
for my $step (@steps) {
    say "Put $step->{name} in the oven, and wait for $step->{time_until_next}";
}

# You can also feed the result of adjust_times to summarise_instructions to
# provide a simple set of instructions, e.g.:
say Convert::CookingTimes->summarise_instructions(
    Convert::CookingTimes->adjust_times(\@items)
);

DESCRIPTION

Often find yourself cooking a variety of things, the cooking instructions for each requiring a different temperature and time?

This module attempts to work out the appropriate oven temperature as an average of all the items, and adjusts their cooking times based on that temperature - so if they're going to be at a higher temperature the time is reduced and vice versa.

Results may vary - providing items with a wide variation of temperatures could result in some foods being cooked at sub-optimal temperatures, and obviously you need to sanity-check the results, and be particularly careful to check that meat and poultry has reached a safe internal temperature etc. This is an algorhythm, not a cook!

SUBROUTINES/METHODS

adjust_times

Takes a list or arrayref of hashrefs, each of which contains details of an item being cooked, with the keys:

name

The name of the item

temp

The temperature the item's cooking instructions call for, in degrees Celcius

time

The cooking time the item's cooking instructions call for, in minutes

Returns a suggested oven temperature, and an arrayref of cooking times adjusted to suit that temperature.

summarise_instructions

Given the results of adjust_times, produce a list of instructions.

For instance:

- Warm oven up to 200 degrees
- Add Chicken Breasts, cook for 5 minutes
- Add Oven Chips, cook for 20 minutes

Returns a list of instruction steps if called in list context, or that list joined with newlines if called in scalar context.
