Today, we’ll use his famous **Yorkshire Pudding** recipe as our base for a math lesson.
Recipe Breakdown: Jamie’s Yorkshire Pudding calls for: - 3 large eggs - 100g plain flour - 100ml milk
Math Lesson
Ratios and Proportions
1. Understanding Ratios
The recipe uses a ratio of 3:100:100 (eggs:flour: milk).
If you wanted to double the recipe, how many eggs, grams of flour, and milliliters of milk would you need?
2. Scaling Down:
What if you only have 2 eggs? How much flour and milk would you use to maintain the same ratio?
3. Fractions in Action
If you make 12 puddings from this recipe, what fraction of the total ingredients is in each pudding?
4. Conversions
Jamie’s recipes often use grams and milliliters. Can you convert the flour and milk measurements into ounces and cups for someone using the imperial system?
Bonus Challenge:
Jamie’s recipe mentions that the oil must be very hot before adding the batter. If it takes 10 minutes to preheat the oven to 220°C, and you start mixing the batter 5 minutes after turning on the oven, how much time do you have left to finish mixing before the oven is ready?
What do you think? Shall we whisk up some answers together?



Alright, let’s dig into the math behind Jamie Oliver’s Yorkshire Puddings!
—
1. **Doubling the Recipe - Eggs: \(3 \times 2 = 6\) eggs - Flour: \(100g \times 2 = 200g\) - Milk: \(100ml \times 2 = 200ml\)
So, for a double batch, you’d need
6 eggs, 200g of flour, and 200ml of milk.
2. Scaling Down (using 2 eggs):
– Ratio of eggs:flour:milk is 3:100:100.
To scale down, divide each quantity by 3, then multiply by 2 (for 2 eggs):
- Flour: \(\frac{100}{3} \times 2 = 66.67g\)
- Milk: \(\frac{100}{3} \times 2 = 66.67ml\)
For 2 eggs, you’d need approximately 66.67g of flour and 66.67ml of milk
3. Fractions in Action
If the recipe makes 12 puddings, each pudding uses:
- Eggs: \(\frac{3}{12} = \frac{1}{4}\) egg per pudding
- Flour: \(\frac{100}{12} = 8.33g\) per pudding
- Milk: \(\frac{100}{12} = 8.33ml\) per pudding
So, each pudding contains ¼ egg, 8.33g of flour, and 8.33ml of milk.
4. Conversions
- Flour: 100g ≈ 0.42 cups (using the conversion \(1 cup = 240g\) for flour) - Milk: 100ml ≈ 0.42 cups (as \(1 cup = 240ml\))
So, you’d use about **0.42 cups of flour and milk
5. Bonus Challenge
- Preheat time: 10 minutes - Mixing started 5 minutes after oven was turned on. You’d have **5 minutes left** to finish mixing before the oven is ready.
How’s that for some math magic in the kitchen? Are your imaginary puddings rising yet? 🍮
