Cooking for a crowd: planning and scaling recipes

In simple words

Making soup for four is like filling a cup. Making soup for forty is like filling a bathtub: you need a bigger pot, more time to heat it, and a plan so it doesn't overflow or go cold before everyone eats.

Before this course: Advanced Cooking: menus, plating and timing (course 12.1.3). You should already be able to plan a three-course menu, run a prep list and a backward timeline, cook proteins to your country's safe numbers, balance a dish and run a dinner service. This course takes those skills to bigger groups, to money, and to teaching other people.

Key facts

Choose crowd-friendly dishes: stews, curries, rice dishes, roasted trays and salads that hold well. Avoid dishes that must be cooked one plate at a time.
The conversion factor scales a recipe: new number of portions ÷ old number of portions. Multiply every ingredient by it.
Example: a recipe for 4, cooked for 30: 30 ÷ 4 = 7.5.
Weigh, don't scoop: at large amounts, weights (grams) are more accurate than cups and spoons.
Not everything scales in a straight line:
Salt, spice and chilli: start with less than the full scaled amount (for example three-quarters), then taste and add.
Liquid: a wide pot loses more liquid to steam. Add liquid as needed instead of all at once.
Cooking time: a full pot takes much longer to heat through. Two medium pots are often easier and safer than one huge pot.
Baking: leaveners and baking times do not scale simply. Make several batches of the tested recipe instead of one giant batch.
Check your equipment: pot sizes, oven space, fridge space and serving dishes. If it doesn't fit in your fridge, you can't make it ahead.
Portion planning: decide a portion size per person for each dish, multiply by the number of guests and add a small buffer for second helpings or a dropped tray.
Write it in your own words: use trusted recipes as a guide, test them, then write your own version. Never copy a published recipe and present it as yours.

Example (a group recipe written for this course)

Chickpea, tomato and spinach stew. Serves 4, scaled to 30 (factor 7.5).

Ingredient	For 4	For 30
Oil	30 mL	225 mL
Onion, chopped	150 g	1,125 g
Garlic	2 cloves	15 cloves
Ground spice blend (read the label)	6 g	45 g (start with about 34 g)
Cooked chickpeas, drained	500 g	3,750 g
Chopped tomatoes	400 g	3,000 g
Vegetable stock (read the label)	300 mL	2,250 mL (add as needed)
Spinach	100 g	750 g
Salt	5 g	37.5 g (start with about 28 g)

Method, in short: soften the onion in the oil over medium heat. Add the garlic and spices and stir for a minute until they smell toasty. Add the tomatoes, chickpeas and some of the stock, and simmer, stirring from the bottom so nothing sticks. Add more stock if it gets too thick. Stir in the spinach at the end until it wilts. Taste, then adjust the salt and spice. For 30, split the batch across two pots.

Step by step

Write the number of guests and choose dishes that hold well.
Pick a recipe you have already cooked and tested for a small group.
Work out the conversion factor: new portions ÷ old portions.
Multiply every ingredient by the factor and write the new weights in a table.
Mark salt, spice and liquid as "start with less, then taste".
Check your pots, oven and fridge space. Split the batch if it doesn't fit.
Cook a half-size test batch if you have never made the dish at this scale.
Check: your scaled recipe has weights for every ingredient, notes for salt, spice and liquid, and a plan that fits your equipment.

I'm learning "Culinary Mentor: cook for groups and teach" on The Future Market. Lesson 1: "Cooking for a crowd: planning and scaling recipes".

What the lesson teaches:
- Choose crowd-friendly dishes: stews, curries, rice dishes, roasted trays and salads that hold well. Avoid dishes that must be cooked one plate at a time.
- The conversion factor scales a recipe: new number of portions ÷ old number of portions. Multiply every ingredient by it.
- Example: a recipe for 4, cooked for 30: 30 ÷ 4 = 7.5.
- Weigh, don't scoop: at large amounts, weights (grams) are more accurate than cups and spoons.
- Not everything scales in a straight line:
- Salt, spice and chilli: start with less than the full scaled amount (for example three-quarters), then taste and add.
- Liquid: a wide pot loses more liquid to steam. Add liquid as needed instead of all at once.

The exercise I'm working on:
Take one recipe you have cooked for 4 and scale it for 30. Write the full table with weights, mark the "start with less" ingredients, and list the pots and fridge space you will need. ---

I'm stuck. Please:
1. Explain the main idea in plain, simple words with one everyday example.
2. Walk me through the exercise one small step at a time. Ask me what I've done so far before giving the next step.
3. Don't just give me the final answer. Help me do it myself, and check my work when I share it.

I'm a parent helping my child (about 8 years old) with a lesson called "Cooking for a crowd: planning and scaling recipes" from the course "Culinary Mentor: cook for groups and teach".

Here's what the lesson says:
Making soup for four is like filling a cup. Making soup for forty is like filling a bathtub: you need a bigger pot, more time to heat it, and a plan so it doesn't overflow or go cold before everyone eats.

The activity:
Take one recipe you have cooked for 4 and scale it for 30. Write the full table with weights, mark the "start with less" ingredients, and list the pots and fridge space you will need. ---

Please explain this so an 8-year-old understands: short sentences, a fun everyday example, and no hard words.
Then give me 3 simple questions I can ask my child to check they understood, and a way to do the activity together, one tiny step at a time.
