Mary's Viennese Whirls

On The Great British Bake Off on Wednesday evening the bakers had to make 12 Viennese Whirls.

The full recipe can be found here but we're just going to focus on the first part of the recipe which is making the jam.

For the jam, put the raspberries in a small, deep-sided saucepan and crush them using a potato masher. Add the sugar and bring to the boil over a low heat. When the sugar is melted, increase the heat and boil for a further 4 minutes. Remove from the heat and carefully pour into a shallow container (pass it through a sieve if you'd rather not have seeds in your jam). Leave to cool and set.

1. Create an algorithm that will solve the problem of making the jam.

2. Label each section as either Sequence, Iteration or Selection.

3. Read through your algorithm:
(i) Does it always make jam? (Is it correct?)
(ii) Is it as quick as it could possibly be? (Is it efficient?)

Extension:
4. Create a flow chart of your algorithm.
