Just before half term, all students in KS3 were invited to take part in a maths competition with a difference. The challenge involved recreating Miss Calleja’s recipe for a Spanish sponge cake, Bizcocho 1, 2, 3 using volumetric ratio.

The recipe is easy: You need 125g of yoghurt, follow with oil, sugar and flour in the volumetric ratio 1:2:3. Add three eggs and a teaspoon of baking powder. The challenge was for students to make their recipe their own by adding their own ingredients or twist to this basic recipe. Additionally, students could look at changing the recipe for a different number of people and the ratio calculations for weight, instead of volume.

The winners were Francesca and Flora in year 7, Lucy in year 8 and Grace in year 9. Prizes were also awarded for best presentation and ‘most out there’ decoration.

Congratulations to the winners!
